[Elecraft] Storing into K3 General Memory

[David Fleming via Elecraft]

Hi Mel,
The Elecraft Frequency Memory Editor reads/writes directly from/to the EEPROM locations where the memories are stored. The MC; command is used only to QSY to a memory. Programming the memories using MC; and emulating button taps will be tricky. Especially if you want to deal with things like split, repeater offsets, and PL tones. It gets complicated. As Wayne suggested, you could possibly save the contents of everything (VFO A, VFO B, mode, datamode, offset, pl tone, etc) and restore them after sending the MC; command. But it won't be easy.
