Carl:
I've got a NC-183D that I'm already pretty well pleased with. Right now
it's used a a band cruiser for AM broadcast, some shortwave and ham AM
up to maybe 15 mHz or so. For SSB I'd just choose a more appropriate
radio although it should be fine for CW.
I've got enough gain to bring the local noise level up to S7 or more
below 15 MHz but I can't say the upper bands are too sensitive. What
sort of improvement did you see with the 6GM6 and 6BY6? Looks like they
have the same base as the originals.
Also, would you guess that this sub would be appropriate for the HQ-145
or 170?
