[GreenKeys] copying RTTY off the air

[Jeff G]

I'm getting the DDK2 and DDH7 freq's in Philly burbs, not strong but strong
enough for FLdigi. ST-6 doesn't like the 450hz shift so its not playing.

It must be a RTTY kinda day, I flipped on the radio earlier after work and
it immediately started playing W1AW rtty bulletin. Now I'm tuning around
and hearing stuff all over, but mostly in 30m, at 850 shift so its
encrypted military I guess.
