ps: Now if someone can give me some hints as to how to add support
for banks "B" thru "E" on the IC-7000, I will be really happy (# 551)

The CIV drivers are a bit messy, but it shouldn't be that hard. I'd
guess one of the zero bytes is the bank number, so I'd just start
incrementing them one at a time until you get back a B-bank memory :)

1. Yes, that's what I thought I'd try as well.  Does Chirp include a tool to send random CI-V commands to the IC-7000, and display the results?  I thought I remembered seeing such a tool somewhere ...
2. On the Icom D-Star radios, you treat the successive 100-entry memory banks as one large contiguous bank;  a good idea for those radios.  However, the IC-7000 has five 99-entry banks, so I think making them contiguous might make for confusing numbering of the memory.  The alternative of creating a bogus entry to make the numbers "match" (which is what I would do if it was just me using the software), would work but could introduce confusion as well.  Creating a separate memory tab for each bank would be best, but I don't know how to do that, and that involves an architectural design issue that should be consistent across radios, I'd think.
3. I haven't done anything to my Chirp repository since I submitted id51.py.  While I can blow away the repository and get a new copy, my guess is that's not the best way.  What method do you recommend?  HG "revert" or "update"?
4. [change of subject]  Yes, the D-Star callsign "tag" field is missing from id31.py.  I'll create a bug, fix it, and submit it.
