I finally decided to try 3.033XA as it advertised a fix for the rx audio
in 3.029. Successfully updated the radio and completed the S-meter
calibration.
Master reset/memory clear - enabled RX-366.
Noticed that without the antenna connected the S-meter was at S3 in USB
mode. Further investigation determined it was not mode specific but
bandwidth specific.
Above 2.4khz = S3 resting level, 2.4 to 1khz = S2, Below 1khz to 100hz
S1 to S0.
No difference between the main or sub (rx-366) receiver.
Observed the noise floor with SpectrumLab so its not just the S-meter.
Went back to 3.029 and all is well.
No noise or S-meter reading at any bandwidth. Am I missing something
with 3.033XA?
