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!
Gary,
Go to the MK II area at www.microHAM-USA.com/Support.html, download the
updated configuration for Writelog and MK II *and follow it* for the
SM6SRW MMTTY Plug-in for Writelog or the XMMT.ocx interface using FSK.
I have just checked and *both* work perfectly at 75 baud. I was able
to transmit at 75 baud and receive on a different system at 75 baud in
either 2Tone or MMTTY (using WinWarbler) as well as the decoder built
into the K3.
You *must* use MMTTY to generate the FSK - *DO NOT* attempt to use the
WriteLog software (or hardware) generated FSK. It appears that one can
not select 75 baud with *hardware* generated FSK and the SM6SRW MMTTY
Plug-in for WriteLog (although it is possible to use Hardware generated
FSK at 75 baud with XMMT.ocx).
It will be necessary to set the baud rate in MMTTY (Options | Setup
MMTTY | Decode tab) ... I recommend defining a "Profile" for 75 baud
so you can return to it quickly. Also make sure "Fixes 45.45" is *NOT*
checked in HAM Default or every time you chick "HAM" the data rate will
be reset to 45.45 baud.
Software Generated FSK is 45.45 baud only and can not be used for this
contest.
73,
