[Elecraft] K4 Panadaptor Display

[Richard Ferch]

This thread seems to be trying to re-invent the wheel. There are solutions
already available.

According to the K4 Programmer's manual (available from the elecraft web
site), "The K4 provides three kinds of streaming data: ..., dB/bin (for
reproducing panadapter data), ..."

This kind of dB/bin data can be used by a logging program to create a
spectrum/waterfall display integrated with the rest of the program,
supporting features such as display of call signs with multiplier.worked
before status, and jump-to-signal capabilities using keyboard hotkeys or
mouse clicks, all without looking at or touching the radio. N1MM Logger+
has had this kind of capability for nearly four years, taking advantage of
dB/bin data supplied in the radio control stream by some radios (e.g. Icom
IC-7300 and newer) or in a UDP stream from a radio or from other software
(the UDP protocol used by N1MM+ is documented at <
https://n1mmwp.hamdocs.com/appendices/external-udp-broadcasts/#sending-spectrum-data-to-n1mm>).
There are other logging programs with some of the same capabilities, with
no need for VNCs, HDMI capture, fancy picture-in-picture monitors, etc.
