  Clatternet is still active, but given current propagation conditions,
10137 KCs does not work for us lately.  You can find us on either 7087
or 3587 on Saturday mornings, 0930 Pacific time.

  We use military standard MARK-LOW tones, with MARK=1575 CPS &
SPACE=2425 CPS, and run USB.  It may be "850 Hz upside down shift", but
our intent was to be compatible with the greatest number of standard
military radios -  on clatternet you'll hear GRC-106 & MD-522 combos,
PRC-47 & CV-2455 setups, TRC-75s, TSC-15s, URC-92s & Dovetrons, URC-94s
& Dovetrons, you name it...
