[wsjt-devel] Hamlib new version fails on YAESU FT-100 VFO handling

[Marco C. <PY...@ou...>]

Hello,

Hope someone of the Hamlib group being sneaking here.

So far my rigctld command to drive my YAESU FT-100 CAT port has worked 
flawlessly:

/usr/local/bin/rigctld -m 1021 -r /dev/FT-100_USB1 -t 4532 -s 4800 *--vfo* &

This by using older Hamlib version:
rigctld --version: rigctld Hamlib 4.6~git 2023-07-20T21:59:57Z 
SHA=aacf06 64-bit

Now, using the new Hamlib version:

rigctld --version: rigctld Hamlib 4.7~git 2025-09-27T16:16:32Z 
SHA=0d122f6b1 64-bit

One of the VFO stays on previous frequency when I switch band.

For example: I start working on 10 meters band then VFOA tunes on 28.074 
and VFOB tunes on the same frequency minus or plus the audio shift.

When I switch band, for example to 17 meters, VFOA sets on 18.100, 
whereas VFOB stays on 28.074!

This is a really annoying behavior!

I tried also without adding the *--vfo* parameter at rigctld without 
success and obtaining a worst and slower switching from TX to RX.

Thanks for any inputs you could provide.
