Don and the group:

 

Holy cow! Don, that (changing (from within WL) the MMTTY's MISC TAB's
sampling rate to 12000 hz from 11025 hz) fixed it! Man, I would have NO WAY
figured that out on my own! But then again there's a lot of settings I don't
know anything/much about in MMTTY and WL... but I now know how to set the
laptop up in portable operation and have it work. I'm happy!

 

I know I'm a bit early, but Happy Mardi Gras!

I don't think I follow this whole thing but I will give it a shot. It sounds
like a receive problem and not a transmit problem. I'm not sure if you are
saying that the problem does NOT occur when using MMTTY standalone on the
laptop? There is no difference in receive whether using MMTTY standalone or
the MMTTY plug-in for WriteLog. It is the MMTTY engine that is doing the
decoding, not WriteLog. So I would venture to say that the problem happens
with both MMTTY standalone and when using the MMTTY plug-in for WriteLog.

 

Try this on your laptop. Go to the MISC tab screen in MMTTY setup. In the
lower left hand side of the screen, you'll see "Clock". Just below "Clock",
you may see it set to 11025 in the pull-down menu. Change it to 12000 and
see if it helps. It sounds like the clocking on your laptop soundcard is
12000 and the desktop is 11025, but it's just a guess. I have the same issue
here. My laptop requires 12000 hz setting and my desktop requires 11025 hz
setting.?

 

Set your Mark to 2125 hz and your shift to 170 Hz.

 

In reference to your laptop only, the reason you probably are able to
transmit FSK with the TX port set to Sound on the Misc tab screen of MMTTY
Setup is because you are using "Software-generated FSK". This means that
WriteLog is producing the FSK and not MMTTY. This has nothing to do with
your other issue though which is receive-related.
