Program Kenwood HT via USB

[BeeRich]

I'm a developer. Got the USB cable to my Kenwood TH-K20A. Outside of programs that are ancient, I'd like to send signals to the unit, but I have no clue about the comm requirements or any protocols that might be standard. I'm guessing there's a way to roll my own.

Any insight appreciated as to how I can achieve this, and any control I can have using my computer.

Cheers

You might talk to RT Systems. Or, buy a copy of their software and reverse engineer it.

Looks like the unit model is not compatible.

Ya that is basically what I want to tap into, but Kenwood hasn't released any protocol information, libraries, that I can see.

They have released info on newer handheld protocols. Most likely, they have not changed much, for the same/similar functions.

Ya it's not about any change of functions. I contacted them and they said "we don't publish anything about protocols over USB." Can you provide a link?

Got an oscillosope? I'll bet it's likely some sort of serial protocol for programming...give it a look-see and find out. If the device presents a USB interface to the computer, it might be a little harder. If the cable has a converter in it to provide serial to the radio, you might be in luck. If you're a dev, this is a piece of cake.

Nope. I'm not sure why they just don't publish any of this. It would make everything better to control it with protocols.

The commands for some Kenwood mobiles has been reverse engineered. Maybe Kenwood uses basically the same protocol for their handhelds.
