Dear WSJT-X development team:
Feature request:
Could we eliminate the Tx Power slider (lower right of main screen)
and replace it with an Rx input level slider (far lower left of screen
immediately adjacent to the Rx dB level) to allow attenuation of input
Rx signal please?
More detail/context:
Elecraft K3S radio with WSJT-X users who use the USB-to-K3S radio
interface can only reduce the input volume so far (typically maintains
60dB WSJT-X level on the Rx dB level indicator). Further reducing
the audio output of the K3S drops the Signal to the point we see ‘jail
bars’ (internal noise).
To enable setting K3S output to WSJT-X recommended 30dB, the above Rx
level slider would help.
Tx slider seems unnecessary because every radio (correct me if wrong)
allows a Tx or drive level reduction on the radio itself).
Very 73,

Hi Dave,
the only input level WSJT-X has access to is in the digital domain, i.e.
after the soundcard ADC, that means it cannot make any useful adjustment
if the level is too high. The level adjustment must be made in the
analog domain before the ADC, in your case within the rig. If the level
from your K3S is too high then something is wrong with the settings in
the rig.
