Re: VO-52



Hi Art,

I don't know of a site for this satellite with operating information. 
However, this is what used to be called a Mode B satellite -- 70 CM LSB 
uplink and 2 Mtrs USB downlink with a reverse transponder.  Because the 
satellite is in a very low orbit I highly recommend a computer controlled 
transceiver (FT-847, IC-910, TS-2000 or etc.) and SatPC32 (you can get a 
free download to test with from Eric's web site: 
http://www.dk1tb.de/indexeng.htm ).  We generally use the "one true rule," 
that is computer control both up and down link to stay in one spot on the 
transponder.

For antennas, we will be using RH circular beams and automatic tracking, but 
I expect you could use an Arrow type antenna with someone manually pointing 
in the general direction -- turnstiles, egg beaters or other omnis may work 
ok but I haven't tried them.

Finally, practice before Field Day to "work out the bugs" is highly 
recommended.  :-)
