All I can figure is - is that you were hearing
the fundamental (or subharmonic) of a UHF
transmission as shown below:
Received Mult. Round
Signal x 3 up/dn
----------- --------- ---------
144.200 432.600 432.600
144.217 432.651 432.650
144.232 432.696 432.700
Looks like 50 KHz steps, but your initial report
stated that these things were 'drifting', not stepping.
