Author Topic: Sound Card or MMTTY ?  (Read 1188 times)

I changed out my old Dell for a newer and faster dell OPtiplex GX620.

Now I can not get MMTTY to run.  I first started with the newer 1.68 version but then went back to 1.65 which was running fine on the old machine. Still not go! The Sound card in the GX620 is Analog Devices Sound Max.

I am getting audio into the soundcard because I can hear it on headphones on the Line Out port.  My K3 is set up OK because it will decode RTTY and display it.  Instead of two-ring figure the MMTTY XY plot, I only get a blob and jibberish printing out.  When running WriteLog, the sound card is able to take WAV files and input them to my K3 transceiver.  So the sound card is not totally dead.

I have been over and over the MTTY setup and am confident that the setup is OK.  Of course I could be missing something.  I am beginning to suspect the motherboard mounted sound card is messed up.

Any tips/tests will be greatly appreciated.  My next step is desperation and to try an outbouard USB sound card.  I read some reports that this might be better anyway.

I was able to solve the problem thanks to some help from the Elecraft reflector.  I had a mismatch between the Mark pitch in the K3 and the Mark setting in MMTTY.  Changing MMTTY to match the K3 fixed the problem.   In several years using MMTTY I  had never run into this before - blind luck I guess !
