Hi Marc.

Welcome to Hamlib.  I've been hoping someone familiar with the IC-9100
and its backend would reply.  Hopefully they will.

I don't think it matters, so probably it is better to not pass the
option.

I think this harkens back to the earlier days when there may have been a
plan to include region specific frequency ranges for backends to check
that an out of band TX frequency is detected, for example.  Personally,
my thought is that such decisions may be better left to applications or
operator knowledge.

I'm not certain that no_xchg is required or not.  Here is what I glean
from the source:

$ git grep no_xchg
icom/icom.c:268:        { TOK_NOXCHG, "no_xchg", "No VFO XCHG", "Don't
Use VFO XCHG to set other VFO mode and Frequency",
.
.
.
icom/icom.h:101:        int no_xchg; /* Off: use VFO XCHG to set other
VFO, On: use set VFO to set other VFO */
icom/icom.h:120:        int no_xchg; /* Off: use VFO XCHG to set other
VFO, On: use set VFO to set other VFO */

If I am guessing correctly, with no_xchg=1 it is up to Gpredict to set
the sub vfo directly.  I hope someone more familiar with both the
IC-9100 backend and Gpredict with chime in.
