[WT-support] RTTY/MMTTY problem

[Kenth Johansson]

Andy,
Which type of radio do you use? With Yaesu  FT1000mkV, as I have, you must change to reverse tone pair in the radio RTTY menu. I don´t know why but it works for me.

  Hi,

  I have asked about this on the MMTTY reflector and had one response "sounds familiar". I have been having difficulty with using Win-Test in the HFCC RTTY contests using AFSK. Operating on Thursday I was receiving well with good copy but when I called a local station he did not copy me. It seems that there is a difference between the tone frequencies on TX and RX so I am off frequency enough for at least one tone to be outside the other stations filter. On Thursday I reverted to using MixW and that worked FB during the contest. Yesterday I did some tests by using the MMTTY engine in DX4Win and that seemed to be OK and also using MMTTY as a full install and that also worked FB. Testing with a different local stn yesterday we measured the difference to be up to 130Hz. In the MMTTY control panel there is a TX offset control which is set to zero. Also I had set up for the standard "HAM" frequencies and neither the AFC nor NET buttons were on. I was wondering if any OTHER USERS have experienced this little difficulty? Having paid for Win-Test I would like to use it for all contest logging. I will still use MixW as my datamodes prog for normal operation.
