Yes, I do understand.  All is well, and functional, no doubt.  (I am 
still considering the CONVENIENCE of holding the hand mic, and having to 
tap (or HOLD) the XMIT switch.  To me, this is a small inconvenience, as 
compared to simply holding the hand mic and pressing the PTT on the mic .)

I really do appreciate your willingness to consider new developments or 
modification!  (Again, to ME, the connector's up-down feature is really 
nifty, but it has an obviously LOWER need, therefore PRIORITY, when one 
considers the PTT function. -Too late for a board mod, at this point, I 
am sure...)

73!
