[chirp_users] "Most unusual" "Radio did not ack programming mode"

Tue Jun 10 18:43:45 PDT 2014

Hi Jim,

Thanks for your comments.  I'll plan to review them soon.  But please also
note my recent comment regarding my most recent success in using OEM
software to upload/download the channel programming to my computer.

As for upload/download terminology, I think typical usage varies by
context.  I think it's a lot like the Big-Endian/Little-Endian issues of
Gulliver's Travels.  It's my impression that the only reason that the north
pole is generally regarded as the "top" of the world is that Europeans live
in the northern hemisphere and have had the most influence regarding
orientated views of the earth.  Otherwise maps might commonly have the
south pole near the top of every map.
