I just received a new-to-me IC-703+. I notice that when using the shift control that I have to move the received passband above the center frequency to get normal sounding audio. This is particularly noticeable in the CW mode. If I center the passband on the center frequency marker using the graph on the display, the audio is significantly attenuated, both signals and band background noise. The manual suggests centering the passband when no interference is present, but this isn't possible.
The radio has an Inrad SSB filter with a passband of 2.1 kHz. The effect is noticeable with the filter switched in or out.
The radio has the DSP option, UT-106.
RIT is off.
The operation of shift function should be identical to the IC-706, if there's any 706 users out there that can offer suggestions.
I've tried a factory reset. (Lock + On)
I'm betting this is a setting that I'm missing somewhere. Hoping it's not an alignment problem.
TIA for suggestions.
