Now I'm in the deep end of the swamp! I just reviewed Don's notes on
setting up for running 75 baud on www.rttycontesting.com and have apparently
stumbled into a conundrum that has no obvious solution. As previously noted
and discussed, using the XMMT.ocx interface with RttyRite set to Hardware
FSK causes severe timing problems and jerky sending of macro messages. The
solution is to go forego Hardware FSK and use Software FSK and let MMTTY
take care of the keying and timing problems. However, in Don's notes,
dating back to June of 2011, it is stated that use of Software generated FSK
will limit the transmit speed to ONLY 45 baud. With Software generated FSK
it isn't possible to achieve 75 baud speed!
So unless I am missing something here, when using the XMMT.ocx interface it
will not be possible to achieve 75 baud unless you use Hardware generated
FSK. But Hardware generated FSK with XMMT.ocx will produce the buffer
timing speed issue that is unacceptable. So now my thinking is that in
order to run 75 baud for the BARTG 75 I must go back and reinstall the MMTTY
plug-in and use that for the RttyRite transmit window at 75 baud instead of
XMMT.ocx? As I am typing this my mind is now asking should I delete all my
RttyRite sections in the ini file an let WL rebuild those too? Life ain't
simple out here on the bleeding edge!

Think I just figured it out. Upon closer listening I don't think my main
RttyRite window is sending at 75 baud! It sounds like it is still sending
at 45 baud, despite the Mode being set to 75 and the MMTTY Decode tab
being set to 75 baud. What the heck else needs to be set?

Subject: [WriteLog] BARTG 75 setup
Ok, I'm puzzled. I'm setting up WL for the BARTG 75 this next Sunday.
I'm using V11.11C with the TU type in RttyRite set to XMMT.ocx as my main
send and receive window. I have a clone RttyRite setup with XMMT.ocx for
2Tone and another clone RttyRite setup with XMMT.ocx using the AA6YQ
FIR512 profile. All windows perform decode normally at 45 baud.
In all three RttyRite windows I changed the Mode to 75 baud. However, in
the clone 2Tone Setup if the speed is changed to 75 Baud it prints my
send macros as gibberish. If I leave it set at 45.45 Baud (with the
RttyRite Mode speed set to either 45 baud or 75 baud) it prints my macros
normally.
In the RttyRite clone window the the AA6YQ profile, if I set the Mode to
75 baud and set that instance of MMTTY to 75 baud, it also prints my
macros as gibberish. Change the Mode back to 45 baud and RttyRite will
now print my 75 baud sending correctly. The MMTTY instance is still set
to 75 baud, but since this is a clone receive window apparently the speed
in that MMTTY instance doesn't matter.
So the questions are, why do both 2Tone and RttyRite clone windows
correctly decode what is being sent at 75 baud when they are set to 45
baud? Also, since 2Tone running in the clone window is not the transmit
window, why does it print gibberish when its Setup speed is changed to 75
Baud? Something seems goofy, but I'm darned if I can come up with a
plausible answer.
