[Elecraft] K4 missing features, was OT: The 4-track mind

[Dave]

Wayne, if you can return to a single track mind for a moment, any update on
when the K4 missing features will be finished?

In no particular order:
1. General coverage, the button still does nothing.
2. Pre-distortion
3. Remote operation via Ethernet

In addition, with the K3 there was an update to the firmware which allowed
VOX to be turned off when the radio was turned off/on. I keep forgetting
and accidentally catching my paddles on my K4...

Now that higher data rates have been approved for the USA, any chance of
fixing the issue where the K4 struggles with Pactor (dropping PTT results
in truncated data transmissions due to TX to RX timing issue), The fix is
to add a 20 mS PTT hold on delay and consider speeding up the throughput to
reduce latency too. The same issue with the K3 was fixed in a week of being
reported.
