Ladies & Gentlemen of the loop -

   clatternet is a teletype net which has been on the air since the year 
2000.  clatternet has a very strong preference for mechanical 
teleprinters but we tolerate MMTTY check-ins (as long as you set 'DIDDLE 
NONE').

   clatternet is always run at 60WPM with military tones -  850 shift on 
USB with MARK LOW.  Our mark frequency is 1575 Hz and our space 
frequency is 2425 Hz.  clatternet has always started at 0930 Pacific 
time on Saturday.

   Lately, clatternet is on 7087 kHz.  That puts our mark frequency on 
7,088,575 Hz and our space frequency on 7,089,425 Hz.

   These tone frequencies were chosen to accommodate the maximum number 
of military RTTY rigs.  Military radios that are usable on clatternet 
without modification include the GRC-106 & MD-522 combination, the 
PRC-47 & CV-2455 combo, the TRC-75, the TSC-15, and the GRC-122/GRC-142 
series.  Of course a multitude of other commercial and military radios 
are usable on clatternet along with an 850 shift TU like the Dovetron 
and many others.

   We would be pleased to have you join us Saturdays at 0930 Pacific 
time on 7087 USB.  With propagation changing for the better, we have 
just moved up from 3580 kHz and hope to get out a little better and 
become more than just a Pacific Northwest net.

   Merry Christmas and Happy Holidays from the entire clattercrew!!
