[chirp_devel] Getting started with the Alinco DR-635

[Nathan Crapo]

Nate,

I recently went through a similar experience with the TH-7800 driver.  I
used Serial Port Monitor 6 to "sniff" the serial traffic while uploading
and downloading the radio via the OEM software.  The TYT software is really
limited, but it does that part well.  Once I figured out the protocol, it
was easy to modify the a very similar driver to work.  I'm betting Alinco
has their own software you can do this with.  Good luck!  :)

Regards,
Nathan
