Re: FDM DUO INCREDIBLY NOISY!!! #fdm-duo
Okay, so I'm home and have tried the suggestions. Here's the answer to your comprehensive help Neil...
What level in dBm does the display show with no antenna connected and with it connected?
Any sign of the PK indicator showing? If so, does enabling the RX ATT menu 1 make any difference?
Does the noise level change if you connect the antenna, or is it bad even with nothing connected?
Does it change level if you select antenna 1 or two on menu 31?
Is anything else connected at all? (keyer, PTT out, ref in, USB etc?)
What settings do you see on the E1 control? Mine has SQL OFF, AGC ON, AGC FAST, AGC TH 3, NR OFF, NB OFF, AN OFF
How about E2? I have RIT OFF, FIL 2700, PITCH 600
I am in USB mode.
