Hi Mike,
Found
your website from the link on MB21……What a
tremendous
selection of stuff you have on your site…..very, very
interesting.
I,
like you am a cat lover, radio lover and transmitter anorak. Although I
now live in Tayside, I’m originally from Edinburgh and I can
still remember the excitement I felt (as a 12 year old) when Radio
Forth 194 took to the air in 1975. Me and
my pals
were hooked, and my interest in all things radio took off from
there. I was never off the ‘phone when they had
competitions, and I delivered the Sunday paper of Steve Hamilton, the
Breakfast Show DJ who lived round the corner from my parents
house. His wife was my English teacher so it was never a
problem
getting a birthday request played !
Re your page
on the Radio Forth AM tx at Colinswell and the reason for relocation
from Barns Farm.
In
the early 1980’s a petrochemical development at Mossmorran
near
Cowdenbeath was under construction (I was an apprentice electrician at
the time and worked on the 11Kv mains power installation) and there was
a pipeline laid the coast where a tanker terminal was being built at
Braefoot Bay. The Barns Farm site was just up from
the
shoreline at Braefoot Bay so I’m guessing that it was decided
that to minimise risk it would be a sensible idea not to have a 2.2Kw
so close to a petrochemical terminal.
I’ve
attached a couple of pickys – One of our sadly missed ginger
puss
who we lost last August – he was responsible for the
amplifier
overheating…….and another of the view from my
kitchen
window of the mighty Angus mast at sunset.
Best
wishes….

Thanks Chris for your kind comments. I will certainly put the
photograph of your beautiful ginger pussycat on our cats page.

Dear Mike, I was just about to give up , then I found your website.
In
the middle of doing too many things at once I picked up a copy of the
ladybird Making a Transistor Radio, last week. I decided I
had to try
making one, thinking , what could be easier.
Well
I've festooned my garden with aerials and earth leads and via a safety
pin and a piece of pyrite I,ve managed to hear some crackles and even a
muffled voice and some music. So, I,m encouraged.
However,
I know nothing about electronics (but am learning) and a major problem
is that none of Mr Dobbs's components appear to exist anymore, and I
dont know enough to know what can be used instead. Maplins seemed at
first a good idea but they appear to stock nothing for these sort of
projects.
I would be very grateful if you
could suggest where people in the know get their components from,
without having to buy things in industrial quantities. I would have
rung Maplins but I noticed just in time that I would have had to take
out a mortgage to pay the premium rate call.
Anyway many thanks in anticipation
Yours sincerely, Dave Schofield.

Hi Dave. As you have found, the components used in some older designs
are quite difficult to obtain, but you should still be able to get hem
from some suppliers. The
tuning capacitor can be of any type or style as long as it is 500pF or
thereabouts. A 300pF one will work, but the tuning range may
be
very slightly limited. I
would search E-Bay first of all and then look out for 'vintage'
component suppliers in Electronics and Radio hobby magazines that you
will find in W H Smith's. A
couple that come to mind are Chevet Supplies and J Birkett of The
Straight, Lincoln. Birkett's often have rare and so called
'surplus' components in stock, particularly tuning capacitors. A
seach of Yahoo and Google for "surplus component suppliers" or "vintage
component suppliers" may yield some results, as may a search for the
Mullard OC71 and OC45 transistors. The OA81 diodes should still be
readily available. Any
modern capacitors and resistors, as long as they are of the correct
value, will work in these circuits. The LT700 transformer should
also be readily available from a variety of sources.
A
good source of components is BOWOOD ELECTRONICS, but maybe not the
vintage ones, though may well be worth asking - the proprietor is very
helpful. See my components
page HERE for some more ideas.
Hope that
helps, Mike.

glanced
across the photo’s from Toronto and the animals and, of
course,
all the Radio memorabilia stuff, better than watching telly and after a

Dear and Julie,
Love
your site and must have another look when time permits! Here on the
Isle of Wight, our local incremental station Isle of Wight Radio has
long been on FM but they started on medium wave in 1990 on 242meters.
Once I was looking for someone and saw the transmitter site, just a few
weeks before they opened, in a farmers field. The aerial had just been
errected, judging by the many deep wheel marks and sign of heavy
activity in the field. Took some pictures. Unfortunately the processor
lost my film!! The mast seemedt o have a twin reflector wire on one
side, perhaps to keep the signal down in the direction of Kent, which
was on the same frequency. Although of low power, if I remember
correctly, their first transmittions brought a reception report from
Poland I believe. [The mast] was quickly dismantled on the move to FM.
Thought you might be interested.
Regards

I
came across your site looking for a radio for my 12 year old to
make. Wow did this take me back my grandpa and I use to make
crystal and other sets the ladybird was the first set I made
by
myself with no help. I am now searching my mom's garage and
attic
for the set and the book. I may have a few old ZN414 or 415s
around at mom's and hope my son can have as much fun as I did
making my radio; Wonderful site!

Hello
Mike and Jules, I came across your "crystal set Website
yesterday---I am retired these days and one of my hobbies is
building fairly "simple" Radios,(Mind you theyr'e not so
simple
to me,as I'm just a beginner at these things.) I
just
wanted to tell you that I find your Website fascinating.---the
Information is explained so well (Even I can understand
it.). The history of Radio has always interested
me,and I
always think--that it was a "Big chance of
Fate" that Marconi, and his contemporaries, discovered that Electric
signals could be sent through the air and "Picked up " by a "Receiver"
some
distance away. Your Website is quite Big,and it will take me
some
time to follow the links,and take it all in---however Ive started---so
I aim to go into "All Areas"
Thanks
,and Best Wishes to both of you. IAN
(March 2006)
Thanks Ian, Glad
you are enjoying the website and the crystal set hobby! These
simple radios are absolutely fascinating aren't they! Good
luck
with your projects, and we hope that you continue to enjoy
the site.

Your web site is very
interesting but I notice that a lot of the audio
clips that you had a few months ago are now not available. Will they be
returning ? Also, in the future, do you plan anything more on
Wiltshire Radio (before the Radio West merger)? WR was one of
the
stations that I grew up with, and I loved hearing, once
again, the Dave Barrett sign-off clip from 1985 that you had
on
your audio section.
Regards H. Ellis
(Jan 2006)
Hi, Thanks
very much for your e-mail. You are quite correct, we did have
a
page of audio clips a few months
ago on our "Experimental Audio" page. Unfortunately it was
just
that -
an 'experimental' section to assess the possibility of adding audio to
this site by using different forms of audio coding and file
sizes. Having run our experiments (a 'test transmission' if
you
will), we then settled on the limited number
of files that we were then able offer via the website, which is what
you will find available now.
Our lack of
available web-space means that we can only offer these
select few files on our site at the moment. This is because audio files
need vast amounts of space compared
to ordinary web-pages and images. We may re-visit
this
web-space problem in the future.
We don't
have
a great deal of other WR information, but if you have
some material, history, information and photographs etc. we would be
only to willing to include them as a WR 'mini-site'. In the mean
time may we thank you very much again for you interest and please don't
hesitate to contact us again if we can be of further help.

Hi
Mike and Julie, What a fantastic website! I love it, I am what would
call a Radio annorak well I collect air checks from on air recordings,
Jingle Packages from various stations including, Key 103, BRMB,
Hereward Radio, Radio 1. I think it's such a great way of remembering
how great Local Radio was and still ys! The Tribute to the
late
Tushar from 100.7 Heart FM is very touching his was a great joch I used
to listen to his shows on Heart the overnight show and Sunday Breakfast
show. We lost a great broadcaster.

Hello,
I have just come across your site and it is wonderful. I was very
interested in radio as a teenager and I still have an original HAC one
valve receiver which my Father helped me build when I was 12. I went to
university and unfortunately the radio hobby got left ,but the good
news was that I managed to keep all my radio components and half built
projects in my parents attic and have been re united with them
recently, including such items as about 40 brand new and unused Denco
Coils in their original tins. I also have many transistors
from
the 70's and also a virtually mint condition edition of the Rev Dobbs
Ladybird book, which I picked up a few years ago for the princely sum
of £1-00 from 'Barter Books' in Alnwick (North East of
England)
whilst on holiday. I have decided to build the radio as a winter
project as per the book. Just wanted to say again what a
wonderful website, I am sure I will come back to it again

G'day
Mike and Jules, I stumbled across your website today whilst googling
around for some info on MK484 radio circuits. From what I've seen of
your site, it's fantastic. There is a lot of rubbish on the web but
occasionally one finds a fabulous site like yours. Congratulations!
I
share a lot of interest with the stuff on your site like crystal sets,
cats etc etc. Why cats.........well my name is Felix! I guess it would
be unnatural if I didn't like cats! My interest in crystal sets goes
back a long way and I'm particularly interested in using them as high
quality AM program sources.
In
Australia I have a bit of a reputation as an "expert" (I hate that
word!), in crystal set design and I've written quite a few articles for
a couple of Australian Amateur Radio magazines and radio club
newsletters and one or two websites. Interesting too, on the Masts in
Malta.
My
family comes from Malta and I last visited Malta back in 1976 (yes, a
long time ago, I was twelve). Anyway, a really beaut website. I will
visit often. By the way the MK484 radio I built today works fine. That
makes two now.

you so much for your kind words, Felix, we're glad you engoyed our

Hi
Mike and Julie,
It
is amazing how one finds a rare gem accidentally and MDS975 is a
wonderful example. Further to buying new HiFi equipment I was looking
at the possibility of boosting the FM reception and I came across a DIY
article in a magazine "Build your own FM Dipole". The example was very
simple and the author explained that he had searched the web for info
with little success so most of his calcs etc. were from text books. I
decided to have ago at building one to his design and out of interest I
checked the web for info. Bingo, my search found 'Make an FM
Aerial' the BBC Way, courtesy of MDS975. What was
going to be a simple Dipole is now a major project High Spec VHF/FM
antenna and it is quite large.
Thanks
for a wonderful site, a feast and a 'site' for sore eyes.

Hello
Mike & Julie,
I
was just surfing the internet for the pin out of a DL96 valve when I
came across your excellent site. I thought being persuaded to
repair a 1953 Bush radio was nostalgic but boy does your site take me
back. Good to see George Dobbs is still doing the QRP bit - I
remember George well from the Lincoln Short wave Club days & of
course those meetings in Johnny Birketts radio emporium on Steep hill
in Lincoln. I was a lecturer in Radio & TV servicing
at the
Lincoln College of Technology and ran the RAE courses.
Haven't
done much in the radio area for many years but your site has re-kindled
a spark I must say. I still keep my G4CLL call current but
have
not been on the air for about 15 years.
Anyway,
many thanks to you both for all the work you have obviously put into
the site and good luck for the future.
Kind
regards &73's

Thank you for
your
web site.
My dad was a radio
ham, (G3EQK), and when I was a child, showed me how to build a crystal
set..which worked great. He was awful in telling me how these
new
fangled things called 'trannies' worked, as he was steeped in valve
technology!!
In 1967, my mam and
dad bought me a 'magnatricity set' which included coils, batteries,
bulbs and compasses etc. I wished they had bought me an 'how to be an
advertising executive set', as unfortunatley I loved the damn thing,
and although a last minute xmas present, all the other toys I just
discarded!!!
Thanks for the walk
down memory lane. I wish you well, Nigel.

looking
at the masts which while I knew existed, dont believe had ever been

David
Rhodes writes about the Ladybird book "MAKING A
TRANSISTOR
RADIO"
Dear Mike and Jules,
I've enjoyed looking at your web site,
and
will come back for a more in-depth look at a later date. I was directed
to it from a search for the Ladybird book on how to build a
transistor radio, and so was pleased to see some photos and schematics
from that - it took me back to the mid 70s when I also built the radio.
I am trying to get hold of a copy of that ladybird book again, as I
have
long since lost mine, and was hoping that you might be able to
point me in a helpful direction (I've already tried ebay and the
Ladybird website).
You may be interested to hear that I
knew
the author Reverend G. Dobbs, as he used to teach me RE in the 1970s.
He
ran an electronics club during school lunch break one day
each week, and so I built the radio under his supervision. I
remember that he had another Ladybird book published on how to build an
intercom - very similar in style to the radio book - which I
also
made in his club. I would also like to get hold of that book too, but
remember it being fairly rare even then, so I don't hold out much hope
now.
With thanks for any help you can give.
David Rhodes
(December 2004)
Unfortunately we
cannot think of any further help with locating this out of print
book. Our own copy is very battered indeed, but maybe someone
reading this can offer some assistance please?

David
Smith kindly writes to MDS975:
What a superb site, which I stumbled on quite by chance, after looking
at an e-bay item for sale, which made a reference to you. I have a
particular interest in both the BBC, and its original transmitter
properties, together with the Marconi equipped sites.
There
are sadly too many sites that were linked to Marconi (eg Bodmin
Radio) that are no more. That one adjacent to the A30 on the end of the
Bodmin bypass disappeared over the summer months last year.
I
am recently retired, and at an earlier time in my working life, was
fortunate to work...with communications, where I spent a number of
years
working on equipment of the valve era, and which brought me
into contact with Marconi test equipment. The company product at that
time was synonymous with quality.
Radio reception
is, and has been a hobby of mine for many years, and consequently I
have
a collection of some of the above companies items. The
trigger
point for my interest was the building of several crystal sets, which were
published in a book by Bernards, given to me by my father. It's good
to see this aspect of basic set building on your web site, it is almost
certain that such beginnings, inspire a further interest in a great
hobby.

John Davis writes
about LADYBIRD BOOK "MAKING A
TRANSISTOR
RADIO"
project:
Hi!
What memories flooded back
when I
found your webpage! I built many ZN414 radios when at school
(1974
- 78) for various people (including teachers!). I built one for a tech.
drawing teacher while at college (1978 - 82) and got 100% in the test
that followed a couple of weeks later, a feat which I never repeated.
I'm not saying that the radio had anything to do with it,
though!!!
I also bought the Ladybird book "Making a Transistor Radio"
back
in 1972 (and remember going into WH Smith and buying it!), which I
still
have somewhere. I find it from time to time, then lose it again. I
never
managed to get it fully working though. It worked upto adding
the
2nd transistor, but adding the speaker and regeneration section seemed
to kill it. I
had (and still have
somewhere)
most
of the parts, so I may have another bash at it. I think I may have had
the wrong value of choke - I assumed it was 1 or 10mH. What was the
value? Can you let me know please? (It is 4.7 mH - Mike)
The
whole reinterest was spawned
this
morning by my daughter who has asked me to
build a matchbox radio, so we visited my local Maplin shop to see what
components I could get. The ferrite rod & 32 SWG wire was out
of
stock (nothing new for them, then....), but got a tuning cap &
MK484
chip. I
routed through the
loft & gleaned
a ferrite
rod & wire from an abandoned MSF receiver project, so I'm up
for a
bit of construction!
I was browsing the net for circuits and
landed on your
page.
Brilliant!
Kind regards, John
Davies.
(November 2004)
John also adds in
a subsequent e-mail: I
dug a bit deeper in the loft and found the Ladybird book. A bit
battered, but found it. Brilliant!! I did a search on the net
for
this and found it for sale at £38. The price on the back is
15p.
15p!!!!!!! I love the drawings
in
there. Beautifully done and very detailled.
Unfortunately
my copy will probably still be worth 15p as I drew in it and put a map
of where I lived at the time, just in case it went walkies. Well, it's
the sort of thing you do when your 10 years old. I
found an OC45 [transistor used in the Ladybird Radio circuit], still
complete with paint. I'll use this in the first stage and the BC212
transistors as the amps. I also found the OC71's, but remember scraping
the paint off to make phototransistors at some stage (Bum!). They were
encapsulated in clear gel. I found another OC45 partially scraped, but
this had light blue gel.
Talking of small radios, I used
to have a
commercial AM only superhet, which measured around 3" square
and
about 3/4" deep and ran from a single AA cell. It was quite loud for
it's size and the battery used to last forever. A mate borrowed it and
it ended up in a bucket of water. I never forgave him for that.

Andy Warner also writes
about the LADYBIRD
RADIO
project:
I just stumbled
across your ladybird AM radio page (while tracking down MK484/ZN414
info.) I remember building that. I also remember a design in
another book that was based around 'chocolate block' connectors. It was
also OC71/OA81-based, but was a 2 transistor design with
headphone output. Anyway, I wanted to say thanks for putting the page
up, I'm thinking of adding the ladybird radio to the long list of
projects that may get done someday. Andy Warner. (Sept 2004)

Hi Mike, Just a short mail
to say thanks for the recipe I found on your site (via Google) for
making a long wave antenna. Living in Denmark but being

to Radio 4 can be an awkward combination. I have also bought
a
Sony 7600GR, so I can listen to World Service, on the occasions I tire

One
of these days I will get my act together and build a rig that allows me
to listen to radio over the broadband, anywhere in the house.

David Taylor has written
in asking
for some more information about crystal sets:
I've just a very
enjoyable hour reading the pages of your website. I had been
wondering what had happened to Lowe (I have a HF-150) as they seemed to
have disappeared from the shelves . . .now I know!!
One of my all time favourite childhood projects was a crystal set
published in Everyday Electronics magazine in what was probably the
early 80s. It was a very simple device built on terminal
blocks
and provided me with my first insight into the world of SWL.
[I
would like] to be able to build [the set] again. I lost the
original magazine article and have been looking ever since.
I would be eternally grateful if [you could
reproduce
the article] on your site.
Many thanks, David. (July 2004)
You can now see my
revised version of the Experimental Crystal Set project HERE!

Jim Simmons dropped
MDS975 a note
regarding the
resistor and capacitor colour code
page:
Great page, good explanations, and very
good photo's. Good for the beginner as well as those that
have
been around for a while (me).
Thanks for the great work.

R. Natarajan also
commented on the resistor and capacitor
colour code
page:
Hi ! Thanks a lot
for providing
such a useful information which I was looking for.

Thanks
to Jim and Natraj for writing in!

Martyn Elmy
writes on the subject
of radio coverage in Suffolk:
Hi,
very interseting site! Do you have coverage maps for BBC
Radio
Suffolk and The Beach?
[Also] do
you have any information on the AM Stereo tests made by the IBA at
radio
Orwell's Foxhall Heath transmitters in the late 70's?
Well
Martin,
the answers can now be
found HERE!

Here is a
message from Mike
Thompson, who is a radio enthusiast and found our radio pages quite
helpful:
Hello,
Stopped to see your site today and found it extremely helpful. My poor
brain has never quite been good enough to grasp all that much theory
about aerials...etc....but I'm about to sling a long wire to a mast in
my garden..and it reminds me when I was about 10 years old..(am now
67)..when I tied a rock to a wire and hurled it high up into an old
garden oak tree and then fed the other end into my bedroom
window...(end
of world war 2 period i suppose).
I
have had an Eddystone short wave valve set over the years...which has
served me very well up to now with just a shortish wire (aerial) in the
attic!!! However with my now advancing years I have decided to grasp
the
nettle...and do a proper job...(smiles). Thanks so much for a
very
good web site.
My
best wishes..(73s).. to you both.
Mike
Thompson.

Well Hi,
I
visited your page while searching for some information about aerials
for
my 'new' (26 year old) radio. I got it for a six-pack of
Aussie
VB
beer. I think I found what I need as a beginner.
I
want to thank you for your page, with special thanks for the things you
like. Spike Milligan is my greatest idol, I have almost all
of
his
books, and the GOONS are and will be breaking my heart
forever.
Fawlty Towers is another show that I prize greatly. I am in
my
early fifties with wife and two daughters...and retired - so I am
trying
to do the things of my dreams now.
Best
wishes and thanks, Andrew
Well good luck with all your dreams
- I'll drink to that!

Great personal
web site, well set
out, links good, pics great, articles brill! May your site
ever
increase!!

Fletcher
Thanks
John,
I'll do my best, but I am rapidly eating through my free web space!!

Just a brief email to say
how much I enjoyed
looking at your website and the diversity of topics it covers. I
stumbled across it while doing a search for articles about short wave
radio. I also have a Lowe HF-225 receiver which is still going strong
after 12-13 years and I can't imagine parting with it. I
notice
they still fetch about half of their original price on the
second-hand market even now, brilliant piece of kit.
I also have taken to DAB digital
radio. I concur
with your comments about sound quality, generally good, but it's
unfortunate that in order to increase station choice, the bit rate has
been reduced in some instances and that has affected the quality of the
sound available, particularly noticeable through a revealing
Hi-Fi
system. It's a trade-off like so many things I guess. Let's hope the
broadcasters avoid the temptation to use compression as they
do on
FM.
I work in the I.T industry... I know a
couple of people
who have embraced Linux in a big way - I can understand why as I also
maintain a Unix system at work and I haven't rebooted it in months -
it's that stable I haven't needed to. You can't say that about many
Microsoft [Windows)] based platforms can you?
I have grown up with both cats and dogs
and like them
both. We've had moggies, Siamese, Burmese etc, the oriental breeds are
particularly characterful, very vocal and usually full of finely judged
mischief! I now have a mog called Cassie who is a white
female
bruiser of a cat with ears like old bus tickets; she is quite
aggressive
towards other cats but very affectionate and very much a lap cat when
indoors.
Anyway,
keep up the good work and all the best. Jon Bignall
Thank you
Jon,
very kind. I love your comment about your cat Cassie having
"ears
like old bus tickets" brilliant!

Thanks for a most interesting
site and
allowing me some moments of nostalgia. [Regarding the Oxford
mast]
I served at Beckley [Oxford] from at its opening 1962/63 but on Friday
16th have the priviledge of attending, in Shetland, the fortieth
anniversary of the opening of BBC TV & VHF from Bressay which
opened
on Wednesday 15th April 1964. Hopefully I might manage some
photographs of Bressay which might be of interest for your site and
will
send these on later.
Best regards
and keep up
the good work, Dave
Stephen
Dave, Thanks for
taking the trouble to write and for the excellent photographs of
Bressay
which are now displayed in the Masts And Towers section.

I've
just been
goggling for some
information on the Le Cars antenna which I live near here in
France. My wife thinks I'm slightly mad to go around taking
pictures of antennae on top of high hills but it's all part of being a
radio amateur! (G6ZKC/F).
Thanks again, Dave Usher
Thank you
very much Dave. Glad you
enjoy the hobby too - so I'm not the only mad one!

I
was just looking for a ZN416 circuit to see whether I could make the
chip work
on 60 KHz for
MSF, and I came across your TRF page. It's very charming, cogent and
well-done. It gave me pleasure. Thank you. Nigel
Good
luck with your project Nigel.

I'm so glad
your site
has a section defending the BBC. It is of course a shadow of
its
former self in terms of programmes, but we have so many friends who
really resent paying the licence fee, and to whom it cannot be
explained
that radio and TV are difficult to fund in any other way without the
price rising to Sky levels. Most of them buy the Telegraph
and
Mail (on continuous order) but their gripe seems to be that they can't
choose on a particular day whether to "buy" the BBC or not.
If it
cost the same as a quality paper I'd have a little sympathy, but it is
FAR cheaper, does not carry advertising to supplement its income, and
has no political axe to grind.

could not agree more, Martin. Mike)

Neil also wrote
on the subject of the BBC:
I'm as worried as
you about the threat to the BBC. My TV will be going through a window
somewhere if the BBC is dismantled. The Americanisation of the UK will
be complete. God help us all! I am wondering if you know of any
established group anywhere who may be coordinating a campaign to fight
for the Beeb before it is too late.
That
is a good question, Neil. I wonder if anyone can inform us of
such a group or organisation.

John writes on
the subject of Lowe radios:
Mike,
I just found your excellent web site after I did a search for the Lowe
HF 225. I own several Lowe receivers including the
HF 225
& HF 150 Europas and regular HF 225's & HF 150's plus
the
complete three piece 150 rack set up (PR 150 & SP 150 mounted
in
the
special Lowe rack). These Lowe's are fun to use.
You
have one of
the finest Lowe sites I've ever seen, good work! I very much enjoyed
viewing your site.
John
T. Wagner, USA
Thank
you John, you are most kind. I found very little on the www
about
these fine receivers, so I felt duty bound to add a few pages with what
material I had. Glad you liked it.

Hi, I'm Pete from
Coventry, great web site, really interesting &
amusing. I'm
glad I found it by accident while surfing. I also
really
enjoy Mike Dickin, which causes me serious mental turmoil as it clashes
with Ed [Doolan], I won't say who wins ;-)
Best
regards, Pete
(I
am glad you found my little offering by accident too Pete!)

Steve e-mailed from
Southend on Sea
and
kindly writes:
Just looked at your website. I
love radio, and
have been involved in it, one way or another, for many years.
I
like the idea of the animals on the site. I have two retired
greyhounds (pictures at http://www.eastbeach.co.uk).
Fully agree with your campaign to save
the BBC. I
generally listen to them on Digital Radio now, and listen more and more
to BBC7. A lot of effort has clearly gone into your site.
Best wishes, Steve Roberston

Just a line to say
that I like your website. I have written about it in the March edition
of Radio Active [magazine]....[here] is what I wrote in Radio
Active:
"
Mike Smith has a marathon website....combining his dual interests of
broadcasting and photography, Mike has produced a work of art, packed
to the gunnels with fascinating facts and figures. The early history of
radio is well covered, and brought up to date with plenty of
information about DAB radio (with links to websites selling them and
transmitter coverage maps etc).
There
are photos and ideas on various aerials to use, including a large
medium wave loop. There is also a BBC Engineering fact sheet scanned in
for you to construct an FM aerial. Get started now and you should be
ready for the spring tropospherics and summer sporadic E conditions"
Best
wishes, Chris Brand.

Just had a look at the
interesting contructional circuits you have on your site.
Well
done in what you have got up and running, I was in the same position in
March of these year and it is time consumming but addictive.
Will
link to you from www.vintageradio.me.uk within a few
days. Keep up the good work. Its never complete!

I found your site
on the net using a
search engine and yours was one of several that came up. I
have
passed your site on to others...all the best and well done.

Brian e-mailed
from Australia about the pirate stations:
I remember pirate
radio and it's birth, probably the happiest days of my life, but still
a pirate radio fanatic living in Australia. I remember when
Radio
Caroline was advertising for dj's and I sent an audition tape! I just
love music and wanted to work on Caroline, but my submission was not
successful! it didn't worry me, I still had the pleasure of the pirate
stations, I even joined the Caroline club!
I still have very
many happy memories of pirate radio and my late teens in London...I am
always wishing if only the years could be turned back, I would happily
return to London in a flash....Australia is so slow and behind music
wise....but my dreams of happiness always will be with pirate radio and
the happy times I had and what pirate radio gave me...
So many thanks have
to be sent to the people who worked on the ships and the forts in such
bad weather to bring us so much good music, they were really were the
unseen heroes of pirate radio. I may be 63 but the happiness
you
gave me (has) kept me young (and) I miss you all.
Brian.
