WE2XGR/2 will be testing in GMSK (Gaussian Minimum Shift Keying) speed 31.25 on 478.000 kHz (dial) 
+800
 for the next several hours. Current transmitter power level is noted in the message. Suitable
 software for decoding (MMVari) can be found at  http://hamsoft.ca/pages/mmvari.php . Sound card
 setup, etc is similar to most other digital communication programs. Select GMSK mode and 31.25
 speed from the pull down boxes. Set RX to 800 and receiver dial to 478.000 USB (unless you prefer
 other settings). If you're unsure of your sound card sampling rate it's probably best to run with
 AFC on.

While not a 'weak signal' mode at these speeds, reports from near and far are appreciated. Always
 especially interested in observations of 'static resistance' and 'fade recovery' ... the two main
 issues with digital modes.
