Thank you for making an effort to provide a detailed description. Part of
my annoyance is bugs are often closed with terse reasoning or just flat out
being ignored. I maintain Chirp on Fedora because I run linux at home so
it's really my only option but I haven't found a very welcoming upstream in
years past. I've volunteered to loan radios (my Alinco DR-635 which I WISH
I could program in chirp... No response.) I've asked for tips on how to
update the Alinco driver. I have some experience with serial communications
so I'm not starting from zero... no response.

Hence my frustrations...

Thanks,
Richard
