For and clean and correct PSK signal the transmitter output should be about
45 to 55 watts max. SP should not be used. What you are seeing is likely
the result of the ALC action, controlling the power output as it should.
Running 100 watts out on PSK will make lots of unhappy folks on the
frequencies adjacent to yours as a result of excessive data sidebands.

Subject: [TenTec] O2 output level with PSK aux in
Using HRD sound card into rear panel auxiliary input. With speech proc
off I get only about 50 watts out with max audio drive measured on rf
wattmeter. The O2 meter shows 100 watts, not 50. If I turn SP on, I can
get closer to 100 watts out. The O2 power meter appears to be reading 2x
what is actually being transmitted? And or the drive level without the SP
is cut 50 percent? What's going on in the DSP? Any suggestions on how to
get an honest 100 watts on Psk? Jim N4BE
