Until the various JT-65 software out there gets an update for the new Icom 7300, we have to cheat to get it to work. Here I show you how I got my system working easily, using only one USB cable to the radio.
Here`s a quick and basic "how to" use the 7300's built in SWR graphing meter.
I think it was an oversight in the manual? Anyway a picture is worth 900 words [-GST] Pretty cool feature. I can imagine all around the world there's going to be 13 short carriers across the spectrum.
Just make sure you turn your power right down to say 5watts for starters. [FYI you dont have to put the radio in AM or FM to get a carrier]
