[Elecraft] K3/0-MINI and N1MM/Remote Rig Polling Problems

[John K3TN]

At the W4AAW remote operation, several K3/0 or Mini users are constantly
getting "Radio Reset" messages from their local N1MM+ instance, which
indicates that the N1MM polling of the K3/Mini (to obtain freq/mode data)
has not received a response for 15 seconds or more.

I noticed in the K3 firmware release notes (below) that a "noise fix" for
the Mini suspends RemoteRig polling during PTT.

Any details on that? If VOX is in use for CW, is the PTT condition mean key
down or during the entire time VOX is active? Ie, would QSK mode result in
less polling disruption than VOX on CW?

What I'm looking for is some way to reduce any disruption across the RRC
link that would impact N1MM polling.

*MCU 4.93 / DSP 2.83, 10-16-2014*

* PSK63 MODE ADDED:  To select PSK31 or PSK63, first tap either end of the
MODE switch to select DATA, then hold the DATA MD switch and use VFO A to
select the PSK data rate.

* KAT500 POWER-ON REMINDER ON K3 DISPLAY: If a powered-off KAT500 is pulling
the auxBus signal low when the K3 is first turned on, "TURN ON KAT500" is
displayed. Previously this condition would lock up the K3 without
explanation.

** K3/0-MINI TX NOISE REDUCTION:  Polling by Remote-Rig units is suspended
during PTT use to reduce a "ticking" noise heard in some cases.*

* Changes to synthesizer, KXV3, and KPA3 device drivers (no effect on normal
operation).
