I was most interested to see this posting on HearSat-L of close to a 
hundred frequencies.  I compared it to the less extensive list in Appendix 
1, "Frequencies Used by European and Chinese Satellites in 1991 and 1992 
as Monitored by the Kettering Group", of "1991-1992 Europe & Asia in 
Space" and was most disappointed to see that while it lists most of the 
frequencies given there, it omits the 2 frequencies of interest to me, 
153.420 and 153.480 MHz.  The very sketchy information I have about the 
Tselina satellites, referred to as second generation HEAVY ELINT and SL-14 
ELINT, says that these frequencies are used by them. 
 
What I do know about the Tselina satellites is that they sometimes have 
become spectacular visual objects.  As best I can tell, this happens when 
they lose attitude control and begin tumbling wildly, so that we can then 
see specular glints (direct mirror-like reflections) off the solar panels 
and other reflections as well.  To confirm this idea, I would like to find 
information about the times when the various Tselina satellites have been 
monitored.  So far, the only information I have comes from a paragraph in 
"1991-1992 Europe & Asia in Space" which reads in part: 
 
    An indication of the status of each satellite is possible via a 
    CW beacon operating at about 153 MHz.  Monitoring by the 
    Kettering Group during 1991 revealed signals from 4 satellites: 
    Kosmos' 1953, 1975, 2058, and 2151 (Appendix 1). 
 
Ideally, I would like to see a tabulation of dates monitored for each of 
the Tselina satellites, but short of that, I am especially interested in 
such dates for Cosmos 1933, 1953, 1975, 2058, 2151, 2221, 2228, and 2242. 
 
I would be grateful for any information, and would be happy to post or 
e-mail current TLEs if anyone would like to have them.  I'd also be 
interested to know if anyone knows whether more launches are planned. 
 
Thanks.
