I heard IO-26 PSK beacon at 23:29-23:43 UTC, 13 Nov 2002, 
 on  "435.812MHz 1200bps PSK(USB)"  as follows.

I observed yesterday IO-26 PSK signals on 435.812 MHz of
the center frequency. It also now appears to be transmitting
on 435.812 lower than 435.822 of the published downlink freq.
Today, I observed again the frequency from IO-26 as follows.

Sat.  IO-26
Freq. 435.812MHz +/- doppler
Mode  1200bps PSK(USB)
Date  23:00:00-23:15:30 UTC, Nov 14, 2002

AOS   23:00:00 435.8213 MHz
      23:02:00 435.8214 MHz
      23:05:00 435.8201 MHz
      23:07:00 435.8163 MHz
      23:07:30 435.8144 MHz
TCA   23:08:00 435.8118 MHz
      23:09:00 435.8077 MHz
      23:11:00 435.8037 MHz
      23:13:00 435.8027 MHz
LOS   23:15:30 435.8025 MHz


I could not digipeat even if via ITMSAT, ITMSAT-1, or
ITMSAT-11.  The "MBL" frame seems to be a safe-mode.
