Since I trade radios a lot and since the Belton Hamfest is coming soon I
am
looking at several transceivers to trade for. I am also keeping my
TS-B2000
that I use now for everything.
The current choices are;
A Drake TR-7 This says it simulates AM with a carrier and only the
upper
side band. That might not sound good
A Kenwood Ts-940SAT
A Kenwood TS-930S.
I would not consider transmitting with any radio that "simulates AM with a
carrier and only one side band". That is not AM. It's just SSB with poor
carrier suppression, or you might say, transmits a pilot carrier for a PLL
BFO to lock onto. It doesn't sound good because of fundamental principles
of the modulation and demodulation process.
The TR-7 does a fair job on receive if equipped with an AM filter. The AM
transmit function, with the audio section turned to zero or disabled
entirely, would make a good stable vfo/exciter unit to drive a
plate-modulated or grid-modulated AM transmitter or final.
