GM Ed,
EV> I built my DX-40 kit over 50 years ago.
HG> My first build however was a 6F6+807 xtal controlled
HG> transmitter
That was in 1951.
After having been released from the obligatory military duty 1952 I
bought a homebuilt transmitter rack containing an 807 PA & AM modulator.
Since the amplitude modulated transmissions caused BCI I built a NBFM
modulator.
The next project was the 14-tube double conversion superhet based on a
danish (Torotor) coil set in 1953. Except the coil set it was built from
scratch.
Next was a transmitter with a Geloso (it.) VFO and a 2E26 PA in 1954.
1955 was the big year when I built a SSB exciter, a chinese copy of the
Central Electronics 20A. I was helped by CE in that I was allowed to buy
the Phase shift network and the PA switched coil assembly. I did also
receive a complete manual and chassis drawing for the 20A. I came on the
air with it in nov. 1955 as the first ham in Finland on SSB.
In 1956 I had a 4 ft. rack fabricated to house a 4-65A PA and tuner on
top, an AM modulator below it and on the bottom shelf a PS for both.
The choice of PA tube was due to the 150W PEP and CW limit. AM was
limited to 50W.
In 1957 the entire family moved to Mariehamn on the Aland Islands after
my XYL (OH2QJ) and I (OH2OJ) had first made a SSB DXpedition to the
islands to put that country on the SSB map.
EV> I put together a Heathkit FM Tuner to use with the Heath AA-32
EV> Stereo Amplifier for my Hi-Fi setup.
EV> That's as close as I've gotten in receiver building.
I have built a lot of Heathkits both for myself and for customers that
didn't they were capable to do it themselves. A National and a couple of
Eico transceiver kits were also built.
I still have a Heathkit Monitor Scope and d:o Panadapter on my ham desk.
Some Heathkit and Eico Kit units for my radio/TV service are now stored
in the apartment.
EV> But I have tinkered with the insides of my Hallicrafters SX-42 a
EV> little bit by looking at the schematic and reading about how to
EV> service it.
Well, the first thing I do if I have bought a new apparatus is to open
it up to see what it has eaten.
