Exactly it is in another directory, seems that there is not continuity
with some of this stuff.

Well I know why mine is not working when I updated the ax25-apps
it appears the latest update now puts the mheard.dat file in the
following location
/var/lib/ax25/mheard/mheard.dat
So I went in and created a symlink in the /var/ax25/mheard directory
pointing at the /var/lib/ax25/mheard/mheard.dat
NOW I have mheard working. I thought I looked at that the other day
but looks like I did not, that was another one of those late night/early
morning things... You know about that...

The first thing I do after the ax25  stuff is up and running and I can see
what is going on the listen screen is do a mheard. That will tell me right
then and there if it is writing to somewhere the client can see.

I agree, indeed I would also like to see fpac complain more loudly if it
does not find things where they should be, but one step at a time.

This is very good, because I know that FPAC is looking for the mheard
data in the /var/ax25/mheard/mheard.dat so worse case can create a
symlink and get it on line correctly.

Again very good, because what happened this last time around was that
it moved the target location.

Yes, I will try to apply it if possible tonight, if not I wil do so during the
week.
