My name is David and I use Chirp for my newer radios.  I have some TK-280's and thought it would be a good exercise to work up the interface and code to program these.  I know, I have no idea.  I will try and keep my questions to a minimum.

Any suggestions to tips or techniques to look into these rigs?

I made the assumption that the existing TK G series in Chirp would be close to what was needed.  Following that idea I tried some of the existing models but the program failed due to a model mismatch, or that is how I read it.  So I copied one model and reworked the entry, put that into the  .py.  Running the program I was able to choose the TK-280 from the list but got this error ...

'Serial' object has no attribute 'setTimeout'

Which is in the program code some where.  Was it reading the usb chip or the radio?
