Hi Guys, here are some shack photos.


Here are the photos of my HT-30 / SX100.

From Roger, WQ9E: In brief the HT-30, 32, and 37 all use very different methods to generate SSB. The HT-30 uses a low frequency L/C filter (50 Khz.) similar to what is used in the SX-96 family of receivers. The HT-32 is also a filter type unit but it uses a more conventional approach with a 5.0 Mhz. crystal filter. The HT-37 uses the phasing method and at the time this was a little lower cost to produce in keeping with the lower price point for the HT-37, it also uses a simpler VFO mechanism compared to the HT-30 and HT-32. The HT-31 was the original matching amplifier for the HT-30 but the original HT-33 (dual 4CX300 tubes) was also advertised to work with it and it matched well with both the HT-30 and HT-32. Later versions of the HT-33 (A) and (B) changed to a single high power final (Penta PL-172) and was cosmetically changed to match the later HT-32A and HT-32B transmitters respectively. The SX-96 and SX-100 were both considered matching receivers for the HT-30, the SX-100 added a notch filter lacking in the SX-96. The SX-101 family was matched to the HT-32 line until the HT-32B version came out along with the high end SX-115. The HT-37 was generally paired with the SX-111 receiver and the HT-41 amplifier which used a pair of 7094 high perveance (fairly low voltage high current tubes, basically behaved like the mother of all sweep tubes).

Here is the Hallicrafters SR-500 console that I had on the Vintage SSB net last Saturday.
It features the SX-100, HT-30 and HT-31
