[Lowfer] PSK31 success last night.

[Neil Klagge]

Hi John. I would be glad to send you some PSK when you think conditions are
right for your reception of it. I have to admit, however, that I have not
had a very strong signal in your direction in the past, and it is late in
the season now. But, nothing ventured – nothing gained. Let's find out
what's possible.

My comment about GMSK is from the experience of others that believe it is
better than PSK on this band. I tried that mode a month or more back and
was copied well in British Columbia.

I want to continue experimenting with various modes. I welcome all requests
to experiment in that regard.

Thanks for your email, John.
73, Neil XSV
