"...there are specific frequencies where when you are tuning one hears a
slight "thump" (as best I can explain it). On 20 meters it occurs at
14172, 14254 and 14335. Other bands have the same "thump" at specific 
frequencies. Do any of you have the same "thump" on your M5's?? It's very
subtle but there. Can anyone expalin why this condition occurs?"
==========
All MPs and Mark Vs have the "thump" you mention.  It occurs every 81.92
kHz on the dial, apparently a harmonic of a digital counter in the radio.

The first one you will hear is at 163.84 kHz (2nd harmonic) and the last
one is at 29982.72 kHz (366th harmonic).
