Sub-audible tones (pl) start off at 67Hz, all the way to 250.3Hz (I think 
that's the top end - can't find my HT right off, to verify.)

Wouldn't take much, Mark, to move the injection point of the pl tone from the 
mic input circuitry, to a more suitable place - you could probably reduce the 
deviation of the tone at that point.
