[Lowfer] WD2XNS WE2XGR/2 in GMSK mode

[JJ]

Jay,
Always fun to try a new mode.
Not as robust as the other weak signal modes.  going to knock the signal 
down a bit and see what it does.

WD2XNS Burlington CT FN31LS testing GMSK 15.625 (200 watt). Reception 
reports appreciated via the Lowfer reflector or direct to 
jrusgrove at comcast.net.

Thanks,
Jon WS1K
