[Orion] Another Orion AM subreceiver bug

Hi Gang,
In addition to the step-size bug  reported previously (the subreceiver 
tunes only in 2.5 kHz steps in AM, no matter what the step size is set to), 
the Bandwidth control for the subreceiver doesn't work properly in AM 
either.  One can adjust the BW down to about 2000Hz in AM, but no narrower 
than that. The bandwidth readout on the LCD reads as if the BW is being 
normally adjusted, but it isn't.  I discovered this when I tried to narrow 
the BW to listen to WWV time signal and filter out everything else but the 
beeps.

There obviously is a significant problem with the subreceiver firmware in 
the AM mode, which TT hasn't been able to fix. Too bad for me, because I'd 
like to use the subreceiver for SWL listening to international broadcast 
stations.

73,
