[RTTY] Signals that don't decode

[Tim Shoppa]

This may have been the first big RTTY contest that I didn't have anyone
call me inverted.

I had a couple callers I could not decode. They sounded inverted but
setting my decoder to inverted did not help. Maybe they were inverted and
ASCII or something.

But there were a couple other funny signals. One, the guy only had a single
tone. It's possible his second tone was at 850Hz or wider shift but I
usually have my audio passband pretty wide and probably would've heard a
850Hz shift. MMTTY and 2Tone did not decode this signal, but Gritty did.
Wow!

I had a couple callers with some sort of very intermittent signal like
their transmitter was cutting out. With enough repeats we got through.

G3YYD - were these problem stations on 40M maybe? There is a time of
evening around sunset where 40M "changes" and local easy to hear (sounds
fine) stations are completely uncopyable due to some sort of multipath
effect.

David G3YYD and Alex VE3NEA - than you SO MUCH for 2Tone and GRITTY!!!
