sorry Bob, that didn't go very well.
I was about 8 mins late after frantically trying to re-program the MD-380 settings.
There seems to be a bug in the programming software whereby if you delete a contact it renumbers the contacts but doesn't update the links between the channels and the contacts, so they go out of step and you end up using the wrong Talkgroup.
(Stu, you'll need yet another version of the file to fix the Talkgroup on Simplex)
Called a few times but nothing seemed to be happening,
I'll keep working on the programming with Stu and see if we can get simplex working next club night.
