[chirp_devel] [PATCH] This is the latest experimential version for the TYT-TH9000D radio driver

[David Fannin]

One other question before I send the next revision for the TH9000D radio.

There are three versions of the same base radio (2 m , 220 and 440 Mhz
versions)  - They all share the same image file format and functions,
except that they operate over different frequency ranges.

I created a base class - Th9000Radio(), and then extend that class for each
of the three models (e.g. Th9000144Radio(), etc) .

The issue with this is that the base class shows up in menu selections as a
valid radio, along with the other three versions.
Is there any way to hide the base class?   Yes, I could make the base class
as one of the three versions, and only extend it twice for the other
models, but that seemed a little klugy.   Any recommendations?

thanks

Dave KK6DF
