[Heathkit] DX-60 Repair Adventure, Which Sideband?

[Robert & Linda McGraw (K4TAX)]

Although DSB suppressed carrier is possible, it will take extensive 
modification of the DX-60.  And those on the receiving end will need to 
receive the signal via a SSB detection system.  I view little to be gained 
from the experiment.

Better to  make some "no holes required" changes in the audio circuit of the 
DX-60, converting it to classic screen modulation which produces great 
sounding audio.  Then drive a linear amp to about 250 watts output.  That 
makes for an outstanding signal.  If you are interested in the changes 
required, I have written info that I'll be glad to supply.  It has also been 
published on some of the AM sites.
