[MRCG] [MMRCG] Teletype paper

[Tim]

Hi Guys - The Clatternet out here on the left coast is currently on "warm
standby" but I can come up on fairly short notice.
I'm running a PRC-47 with the CV-2455 RATT converter.  Unfortunately no
mechanical terminal here so I have to use an ancient DOS laptop as a glass
terminal (horrors...).  We ran the weekly net for several years, usually on
3587 but 7087 and 10137 also work pending propagation.

We've worked Jim, W6JVE several times from Arkansas so a hop to the east
coast should be OK, on 40 or 30 meters.

Signal is the usual 850 cps shift, space high.  Other details here:

If you want to try, shoot me an EMail to coordinate a test...

73, Tim
