[GreenKeys] the rtty blues (still)

[David Ross]

Gil -

  Where are you located?  In the northwest, you'll hear the RATTS NET
on/around 3613 at 8PM weeknights -  all those folks run PC TTY setups
and the net is 170 shift.

  Or hear 850 shift on clatternet  -  10137 at 9:30AM Saturdays.  If 30
meters doesn't work for us, we'll go to 7087.  We use military tones - 
MARK=1575 & SPACE=2425 on USB.

  Yep, encryption is so cheap lately that it is real rare to find a
commercial or military sig that is not encrypted.  Probably 95% of RTTY
is up on microwave links anyway, either terrestrial of satellite...

  I have a C-band satellite TV receiver here -  hooked an HF receiver up
to it once and heard lots of RTTY sigs, but was not set up to print at
the time.

  If you have an old C-band satellite receiver, you can either:
 -  listen to your satellite receiver's IF output with an FM receiver
that'll tune from 50-90 MHz (Most C-band receivers have a 70 MHz IF and
sigs are about 40 MHz wide).  AFC will be almost essential for this
mode.
 -  listen to your satellite receiver's baseband output with an HF
receiver.  You'll have a TV signal from DC up to around 6 MHz, but from
like 6 MHz to 11 MHz is usable spectrum and you'll hear some RTTY
there.  Signals will be perfect, they'll be very strong and any drift
will come from your HF receiver since your satellite receiver is locked
to the signal from the satellite & originating station.

  Does anyone have any experience with RTTY sigs "hidden" in the 10GHz
commercial TV band (like DishNet & DirecTV)?

good luck
