Just curious..., what is "the radio group"?
I have two old radios and an old TV. I would have to go back home and check
to see what models the radios are. The TV was built in 1948 at RCA in
Camden, NJ. I bought it at a yard sale near there from a guy who used to
work at RCA in 1948 on the TV assembly line and this TV was one that he
helped build on his line.
I also have a hardware store near me that did an interesting thing with an
old stand-up small screen TV. They used just the TV box, and inside the box
they hid an old portable black and white TV, and they plugged a VCR into the
hidden portable TV. They play old black and white Honeymooners TV shows on
the VCR through the portable black and white TV that is hidden inside the
old TV box. So, when you walk into the hardware store, the old black and
white TV looks like it works and it looks like the Honeymooners is on TV.
My first reaction was that they had an old small screen upright black and
white TV that actually worked, and that the Honeymooers just happened to be
on TV at the time. Then, of course, duh, I figured it out -- but it is a

I've been fooling with vacuum tube radios for 50 years now.
It's a nice break from computer repair.
When I was still repairing radios in the late 40's. I was working in a
retail appliance ? radios store that also did repairs on these things. I
always welcomed the tough ones to repair. A console came in dead. One bad
and one weak tube. Easy repair. BUT.. when I fired it up it had a "chirp"
about every 20 or 30 seconds. Did a major inspection and testing of all
parts including opening up the IF's and checking any resistors or capacitors
in side them. Still chirped. The boss came into the repair area and said
He had been hearing the chirp over a long period of time. Noticed a flashing
sign in the store window flashed every time it chirped. There was a small
disc that was under the light bulb base that would cause the light to
flash. Shut it off , problem solved. WW
years ago, the company I worked for manufactured control circuits and
we'd retrofit a lot of industrial equipment.
After we tested it out, we'd slap our company's sticker on it and
jokingly quote Zenith:
The quality goes in before the name goes one.
As a matter of fact, Zenith in Chicago was one of our customers.
The speaker works, the receiver used to work, but not very well. My dad
then took the tubes out to test them on his tube tester and get
replacements for bad ones - and misplaced them all. It wouldn't have
worked anyway as the other components, especially the caps, were too
old and dry.
I vaguely recall those.
My first s/w rcvr was a Knight Kit "Ocean Hopper"
Plug in coils and regenerative. It was nothing to brag about. I later
got an HQ-110-C and later a Drake 2A
Until I got that R-100 all I had left was my HQ-140-X
For a transmitter all I have is an old CB set I converted to ten meter CW
You all telling us how old you are..... Ever built a real thing like KW
xmtr with AM modulator? I used lot of military surplus. best I liked was
BC-610 TX, R390, R392 RXs Also BC779 Super Pro. Up until recently I had
HQ170, HQ180 RXs collector quality with matching speaker cab. I sold
them to a collector. I still have complete set of Collins S-line meat
ball emblem series C model. That is only tube gear radio. All other tube
gear is guitar amps full of basement. Fender, Marshall, Guytron,
Mesa Boogie, etc. plus couple home brew Marshall, Fender clones. One
converted mono block audio amp(2x6CA7 P-P output) cloning Marshall JMP
fooled every one on blind test. They couldn't tell the difference
between original and clone. I still have Heathkit GDO, a tube tester,
hombrew noise bridge I use frequently. I am still active on the air with
all mode QRP plus my favorite 5W rig(this is all digital with DSP and
brick filters w/built-in iambic keyer. My call is VE6CGX. I seldom use
ICOM IC-765 heavily mod'd TRCVR, Yaesu FT-736R fully loaded all band all
mode TRCVR. it can even do 1GHz microwave QSO. SWL rig is JRC NRD-535D,
also I use mod'd CB radio for 10M FM repeater work on DX. This unit is
good to check on 10M band condx.
I lent out my GDM to someone years ago and doubt I will see that again.
All the Ham Gear I had back in the old days is gone. I never did get any
of those military surplus radios and I wish I had.
One of my friends picked up a couple a radar units and converted them to
1296 mhz ...that was in 1965 or so and that was considered quite
advanced in those days
I did homebrew a few things...such as a six meter transmitter plus I
built a modulator for my transmitter. It was an odd setup...being a
/cathode/ rather than a plate modulator. Since it went between cathode
and ground it reduced the transmitters power, but it worked well.
Even though I got rid of several truck loads of ancient test equipment I
still have some smaller items left...such as a six amp rectifier tube
(next to an 85 amp silicon diode)
