Hi,
I searched through the archives and found mention of a mod (from Ten
Tec) for QRPp levels. It involves putting a 3V zener diode in parallel
with the zener diode D3 on the low level driver board. One end is at
ground
so the diode can be switched in and out with a rear panel-mounted
switch.
Has anyone made this mod? What is it's effect on SSB (I assume that's
what
it achieves as very low levels are possible on CW without any
modification)?

I'm using the Receive Antenna socket with the switch in the TRX position
to
connect to the independent Rx connector on my transverter.
