Hi
Ron
?
I like
30m too. One of my other projects is a miniature CW transceiver for 30m. Nice
job on the 30m rig, I hadn't seen that on your site before, I think it is newer
than when?I previously visited. I have a 30m direct conversion receiver see
?but
it suffers from plenty of broadcast breakthrough. Nevertheless I had some nice
QSO's on it including my first Italian station. Perhaps when I am next able to
get my station QRV again on 30m we can try a QSO! PA might be a little too close
for 30m though, except under unusual band condx.
?
Hmm so
you have teletubbies too. My daughter loves them. She's 2 on 1st April. Only
problem is, she gets very angry when the programme finishes and blames it on me.
What does she want me to do? Telephone the BBC and ask them to play it again? Ah
well, guess I shouldn't have dismantled the video recorder? ;-)

Hello Hans,
?
Tnx very much for your message with all the good information. I enjoyed
your dedicated ECL82 experiments. 30 m is a special band. I made this 30m-CW
rig working on 10.106 and 10.116 MHz Xtals and irf510 in the PA. I like the
clicking of the tx relay when the thing is transmitting. And yes I can give cq
cq while soldering :-)) Made about 50 qso's with it now (SP, D, I, OM, OK).
Since i do not speak morse, i use cwget and cwtype on my 266 MHz celeron, and
it works great. I am surprised the dc receiver with so41p works great with my
14m attic antenna.
AM broadcast break-through is minimal.
Have a look at ?.
Only Dutch i am afraid. Translation to follow.
The 30m beacon results on the hidden page are very original. Nice
graphics and diagrams. This really starts to look like science. Must have
taken you a couple of days to collect all data.
Sure I know Tinky-winky, Dipsy and LaLa !! Tweenies are new for me. I'll
ask my son, he is 9 and probably knows...

Hello Ron om
?
My
2-year old daughter isn't ready for Squarepants yet. She still likes "The
Tweenies" and "Teletubbies". These are probably very UK specific and you
don't know what they are... please don't ask! Sometimes I make her watch Tom
& Jerry instead, so that I can enjoy it too ;-)

Someday I would like to make an entire transmitter (and maybe
receiver) using homemade components, including homemade valves. More dreams
for the future.

You asked about my beacon - there is another "hidden" page
?which
contains more recent experiments and results. Recently I built a DDS
generator to obtain a rock solid, predictable frequency source for the QRSS
beacon. See ?.
Again, no microcontroller. My 30m QRSS beacon is currently QRV to an attic
dipole, on frequency 10,140,050 +/- 2Hz. The message is my callsign in
QRSS3, followed by slow-Hellschreiber (14Hz "height", 1 second half-pixels,
i.e. 98 seconds per character), followed by my "crown" signature trademark
repeated 6 times and of course a quick 12wpm CW ident. Power is 250mW
estimated. You need spectrum ! software running on a computer to be able to
decode this weak signal. But it's there 24 x 7, European listeners should
have no trouble finding it.
?
There are other non-linked up pages on my website too. The
place needs some work. One of these, is the page about my modifications to
my 1-valve ECL82 80/40m CW transmitter which is still the ONLY transmitter I
have ever made QSO's with (550 in total, now). The BITX20 awaits debugging
of the PA. I converted the TX to operate also on 30 and 20m. I added coil
taps and crystals, so now have 8 installed: 3.558, 3.560, 7.010, 7.030,
10.106, 10.125, 14.060, 14.060. See ?.
The reason I mention this, is that you will notice if you scroll down, that
I modified the TX also adding a keying relay, then connecting everything up
to my QRSS beacon controller... then I programmed (by hand, with the toggle
switches) one of the 8 EEPROM channels of the beacon, to contain: "CQ CQ CQ
DE G0U! PL G0UPL G0UPL CQ CQ CQ DE G0UPL G0UPL G0UPL K" wait a bit, then
call again. This is hilarious! Lots of relay clicking. So I can call CQ
without touching the key. Great so I can continue soldering the projects
while I call CQ. I am now at the stage where my CW is good enough that if
condx are good and the other op sends reasonable CW, I can just about copy
him in my head without writing everything down. Which again, means I can
continue my soldering even during a QSO!
