The IC-M710 is a marine HF radio - SSB/CW/FSK - up to 150W. It's tuned by selecting pre-programmed channels, with separate RX & TX frequencies. There is no VFO tuning as we'd use it on the amateur bands - and this makes it awkward to use.

(There's a MIC plugged in mainly because the RX audio loops via 2 pins in the mic, so unless it's plugged in, or the link is made in another way, there's no RX audio!)

I wrote a few different control programs in Python to make things a bit easier. This one seems to work ok. There's also a user-programmable bank of presets - presets can be added from the main control panel by pressing the Store button.
