Thanks for the very interesting comments. I have been thinking it was
probably just me who was experiencing the phenomenon of hearing stations
work others that I never hear again. It is very enlightening to hear
that you, a much bigger station further south, experience the same
thing. One factor for me may be reduced activity up this way compared to
the past, making it less appealing for people to spend much time looking
this way. We have lost a lot of VHFers up in my neck of the woods and
further north/east for various reasons. I'm doing my best to see that
FN55 doesn't go quiet as some other grids have!
I had similar results listening to you running meteors with W0VTT. We
seemed to hear him at different times. I think that is pretty common
with meteors and is one reason so many stations can effectively share a
frequency without many collisions.
That phenomenon you have with MSK144 transmissions starting late is very
curious. When I first noticed it, I suspected my clock but I checked and
it was exactly correct. Then I noticed your transmissions were ending
exactly on time. Hopefully you will be able to figure out what's causing it!
