Thanks. I got a chuckle out of that RME comment.

Hopefully someone will appreciate the HQ150 I've got on the auction right
now...

My favorite 'sleeper' radio with tubes is the Hallicrafters SX-117. Great
audio, good filters, strong front end, and can be modified to a form that
is superior to a 75A-4 with all the mods. 80kc to 30Mc coverage with the
LF adapter and a handful of xtals or a synth for the first conversion
oscillator. Tracking filter after first mixer, like the 75A4. Can put in a
sheet beam or Pullen first mixer, like the 75A4 mod, Can put in a sheet
beam product detector, and the audio through that 50kc IF sounds so much
better than the collins mechanical filters. 50kc Q mult is easy to add.
The only thing it doesn't have is the passband tuning, but for a 99% CW
op, the BFO, notch, and tunign knob do the trick. Can use a 2BQ or a 2CQ,
or build the Q mult.

I do like the 51S1 but will never spend the $ to own one.
