There is NO controller in the DeskTrac repeater. There is a interface between
the receiver audio and the transmitter audio input, and a simple dropout timer
in the RUS to RPPTT. None of these are in the programming/RSS.
Look for the RPTR DISABLE led on the front panel, this breaks the PTT line
As long as the Spectra is displaying the OUT RNGE message, it is trying to get
a control channel and is locking the BUSY or DATA lines, the RSS can not read
it.
Try changing MODEs until the radio is not displaying errors, ect. Then READ.

Yes there have been many 900 Spectras over the years that exhibit poor receive
