[MRCG] Clatternet Schedule for Sunday 8/3/2014 20:30 TONIGHT

[Tim]

Wilco...

I'll be up on 3600 at 8:30 PDST tonite.

Stock PRC-47 USB with CV-2455 RATT convertor.  3600 Kc "window" frequency,
850 cps shift, Mark Low (I think!  LOL), 45.45 baud, 100 watts initially.
No diddles...
I will also receive with an R-390A and fldigi in case something is "off".

chasing out cobwebs...Tim
