Hello,
I need to replace one of the red USB/LSB indicator lenses on a TR-4C
faceplate. Does anyone know of a source for these?
Thanks,

Power up, good receive on short 20' wire, s-3 steady, couple of jumps to s-5 on
strong 20 meter signal. S-meter drops to zero, and no movement on w-7 meter on
transmit test, two differet 7077, A-104 mics.(300 watt drake dummy attached to
W7) mid 3k range, all late boards, including aux7, NB,
Ken,
Have you tried CW mode to see if it is related to the audio chain vs more or
less just the RF chain?

Is there any difference between a PTO and a VFO? The R-4 has a PTO and the R-4A
a VFO per the specs.

Is stability the only advantage to the R-4A's semiconductor VFO? Is there any
hum, like that from a freq. synthesizer, from solid state VFO?

Are you guys tired of my MN2700 saga yet? I certainly am!
Anyway...
One of the little cylindrical push-on knobs on the two horizontal
reactive range switches broke apart when I grasped it and I think the
other one is cracked and not far from breaking. Does anybody have
any spares or know
