[Elecraft] How reliable an internet connection is needed for A K3 remote to work well?

[Gerry Hull]

Barry,

Do a long series of pings (ping address -n 500 will let it run 500 times)

Jitter is the difference between ping times  (100ms ping and 120ms ping is
20mS jitter)

"My remaining question is - in the presence of a somewhat flaky Internet
connection, for whatever reason - latency, jitter, etc. - is there any
problem with the K30 control of the K3?  For example, when turning the AF
gain or tuning knob, will they follow well, or will there be dropouts of
radio commands, hinder reliable operation?
​"

Yes, everything will go to hell if internet connection is bad... knobs
don't react fast, display does not update fast, etc.
However, don't panic.  Unless the problem persists, it will go away quickly.

Hint: Don't turn knobs like audio or power fast.  Each pulse from the knob
is sent as a UDP packet... If you turn too fast based on the connection
speed, the vlue won't change much.  Turn slowly and it will update
regularly.

I found that with our PR1T connection, screen updates and knob turning
would recover, unless the connection went down for a long time, and I get
that DANG LOUD
SIT tone in the remote.   If I get that, I just cycle the power on the
front panel of the K3/0 mini, and it ususally comes right back.

-Gerry
