Thanks for the suggestion. The Jabra module might be a workable solution for me, although 30 feet range will barely reach the end of even our small garden. I could use remote desktop to access the rig control application, so I wouldn't need Bluetooth serial, though I do have a couple of Bluetooth serial devices that I bought on eBay on the off-chance they would come in handy for something like this. Is there a Bluetooth headset that has headphones and a boom mic, or must you use one of those small mobile phone headsets? > I do have access to a embedded system that comes with a ARM7 µController. > It should be possible to run an embedded Linux at that device.

If I did, I'd go for an external box that plugs in to the RS-232 port and line in and out jacks on the radio side, and ethernet on the other. You'd need an on-board sound card, of course, to digitise the audio. Using Hamlib for rig control, the device could work with any radio, so the market for it would be much bigger than just the K3. I'd have thought such a product would be commercially viable, wouldn't you? ----- Julian, G4ILO.
