[RTTY] BARTG 75 Sprint calls

[Gary AL9A]

Ok Ray, thanks for "fessing up" about your problem.  That confirms my 
suspicion that it is possible to receive 75 baud and transmit at 45 baud 
unless you have all the check boxes correctly set.  And sometimes even that 
doesn't work.  I had a couple of times last weekend where I would set MMTTY 
at 75 baud and then after a couple of QSOs I could only get garbage.  When I 
went back to the MMTTY setup screens I found that somehow the 75 speed 
setting had reverted back to 45!  This happened a couple of time to me. 
Stray RF?  Dunno, but it finally settled down.

Gary,



I plead guilty to calling *W0 - - * a couple of times and slowing him down
as he politely did exactly as you did, in sending me a "75 not 45" message.
After my double-checking that "75 baud" was defined in setup and it didn't
work twice, I decided to give up, not bother anyone any more, and await a
time to get it explained.



Your #1 comment fits me. I changed the WL MMTTY options to 75 baud, but
didn't read the post that explained unchecking the box "Fixes 45.45 Baud"
until (of course) 20 mins after it ended. Frankly, there are a LOT of
WL-MMTTY setup choices I don't get - at all. But I bumble along.



So yes, I decoded 75 and apparently sent 45. Ptui!



Your #2 possibility didn't happen with me, but might have with others. Is it
possible someone (especially a RTTY guy) would try to work a spot without
decoding anything looking like a call? If so, I suppose it takes all
kinds..don't guess he gets many QSL's..



So I hope the mystery has properly been explained. Next year 75/45 karma
will surely haunt me - and yes, I WILL have a macro for it - har!

For some reason in this one I noticed a significant increase in the number
of stations that called and tried to work me at 45 baud instead of 75.  I
got so tired of manually typing "SEND 75 BAUD NOT 45" or something close to
that I wished I had made a macro someplace to save my finger tips.  I
couldn't figure out how someone who was setup for 45 baud could call me at
that speed when all they could receive was gibberish.  Now I suspect two
possible scenarios could factor into this, but I'm not sure of #1.



1. Someone has setup MMTTY on the Decode tab to receive 75 baud, but missed
clearing the little check box on the Demodulator tab that "Fixes 45.45
baud".  So my question is if someone did this would he be able to decode my
transmissions at 75 baud, but then when he sent his macros they came out at

45 baud?



2. A much more likely scenario is that a few saw my call spotted on the DX
cluster and ran there to pick up a AK RTTY contact despite the fact that
they couldn't decode what I was sending!



Do either of these assumptions seem likely?  Not sure what to do about it in
the future.  One thing I will not do is shift my speed back down to 45 to
tell the uninformed at the other end to increase his speed to 75.  That is
sure to result in my pile up disappearing when the other guy needs
instructions on how to change his baud rate!
