[BUG] RXatt value is offsetting transmit DUP display, pan and waterfall. #482

Closed RdWing closed 2 months ago

RdWing commented 2 months ago

In dev8, it appears that the current RX S-ATT value is positively offsetting the dup display by however many dB of attenuation is currently set.

This is causing the DUP display to appear at a much higher level than reality. I only tested on RX1 but it might be present on MultiRX and RX2 also.

To Reproduce Go rx somewhere you can tx. Set S-ATT RX to 0 dB. Set Drive and Tune power to 5w. TX TUNE and measure peak level of carrier on DUP display. (-16 dBm) Adjust S-ATT RX to 31 dB. TX TUNE and measure peak level of carrier on DUP display. (+15 dBm)

Expected behaviour The value of S-ATT RX should not be used to adjust the amplitude of the DUP display.

I believe this is related to Pull #435.

@RdWing thanks for spotting this, it has been there since dev4. I will probably release a patched dev8, dev8b

With 8B, the autoagc no longer works correctly and settles way above the noise floor. I expect this may be tied to the above attenuator issue Ed W2PH

I have updated your bug report #483 , with a video explaining how you can change settings if required.
