[Icom] IC765 on 60 meters

[George, W5YR]

Pete, I just ran the PSK31 IDLE two-tone test on the 765 and set things up
the same way I do for the PRO2: 40 watts PEP output and 20 watts average.

The 765 produced  the identically clean - perfectly clean - two-tone r-f
envelope signal and the wattmeter showed 40 watts PEP and 20 watts average.

All this at 5346.5 kHz. As I stated before, max RTTY carrier signal out is
105 watts at that frequency.

I didn't check for spurs but I would be hard put to expect any from the 765
with that caliber of on-frequency performance.

The big problem with the 765 is limiting the transmit bandwidth. My next
step is to measure the occupied bandwidth of the 765 at 50 watts output in
the USB mode. Then we will know where we stand.

More later . . .
