If I increase KENWOOD RESPONSE TIME, things seem to get
better, but there is still variability in the amount of time that the
program recovers from a period of tuning the rig, with that amount
of time being some numbers of multiples of KENWOOD RESPONSE

Without watching the data going back & forth between the two to
be sure, it seems almost like sometimes the radio might be better
off if it hadn't have been polled or polled as many times during tuning.
Maybe determining tuning is taking place when so much change in
frequency is seen since the last poll & implementing something like
this is not so simple as it seems to this layman.  I could even be
wrong about what I think I'm seeing going on... ;^)
