constant power SSB
Posted: 01 Feb 2023, 12:21
Hi,
Long ago I used PLL-SSB, with constant power output.
This worked well with DX, but also prevented LFD a lot.
(the drawback was a wider tx spectrum)
I would like to find out if I can use the uSDX for this purpose.
No unit has been bought yet.
With the "old" system a carrier (at zero beat for the rx side) was transmitted in case there was no audio input. So the RF output was always without any amplitude component
At PA setting 8 the uSDX does transmit only phase information (according to a video).
In case of no audio input, is there a carrier transmitted?
I do hope someone can put some info on-line.
