Hi all,
good point Guy, CPU time shouldnt be a problem anymore
(for those with older or slow cpu the option can stay false)
The practical limit could be the radio response time:
radio cpu speed and line speed.

I deleted a message from Tree talking about
the delay from a radio and about the 2400 bps speed.
in any case we are talking of milliseconds or tenth
of milliseconds.
Do we want to say 100 ms? 200 ms?
Yes 200 could be good, and your eyes shouldn't
recognise the delay of the freq reading versus knob turning.
Whatever the solution Tree will find (and will be a good one)
I think this poll delay should be programmable as an option, 
and CW will not be disrupted (no need to poll during PTT!!!!)
so if PC in sending CW you have no need to tune the band!!
so no need to readout the freq., even on the 2nd radio
if you use it.

The CPU box that is in the station slot is a PIII running at 825. It could
poll anything that moves in that computer and read another chapter in the
novel in 10 microseconds. If we could set shorter intervals, the frequency
updates would move in tune with the knob. Is there a practical limit in the
polling interval to an MP, for instance?
