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. 73, Rich VE3KI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
