Hi,
I have heard ON4UN on a number of occations fairly recently and found that
his audio *is* relatively bad. I suspect that he has an RF feedback problem.
Can anybody else confirm this? I have been very surprised that nobody has
mentioned this to him on the air, so I have held my tongue on the issue so
far.
Anyway, in my opinion it's not fair to play back recordings of people's
audio over the air. It's much better to record his audio with something that
can be captured to a file and send that file to him. Audio deterioriates
very rapidly from multiple passes through SSB receivers/transmitters. I have
heard many times people proudly playing back recordings and they sound
nothing like the original.
