[amsat-bb] Re: Yaesu FT-897 and HRD satellite tracking problem

Dave,

I had forgotten about this, but there was a satellite rig years ago which in fact had a "feature" which blanked the RX whenever the frequency changed. The fix was to clip the transistor used to short the output. Perhaps you can determine which is which by using another RX to probe for RF pulses around the CAT and other lines?
