Update on the driver for the Jetstream JT2705M . It looks like Jim's observation is correct - the JT2705 looks like a variant of the 8900.

I successfully did an image download from the radio by adding a class to the existing Btech file and updating the magic and fileid. I was able to get an image, and also it displayed the channels correctly (need to do more testing to make sure this assertion is correct.).

I posted the image on the ticket: http://chirp.danplanet.com/issues/3481

I'll do some more work to test this out, and I'll post a patch for the btech.py file when I'm ready (most likely later this week). Since this model is under active development, let me know if there are any issues or updates that I should be aware of.

thanks

Dave
