Recorded on 145.825MHz at around 20:57 BST, in IO75ww - I have no idea
what it is.
From the way it faded up and down I'd guess it was something in orbit
but I can't figure out what.
Has anyone decoded any tlm channels (that aren't dead)?

I'm assuming space-track.org has taken the place of the old NASA O.I.G. site
that I remember using several years ago. Thanks again to all for the

Can someone tell me the major difference between the two downconverters?
Ten years ago or so, I used a 3733 un-modded at the fed point of an 8ft dish to
copy ao-40 tlm. Today I read a lot of references to the 3731, but not much about
the 3733. Just wondering if one is preferable to the other.
Thanks for the links, Ron. It's been a while since I've dabbled with 2.4ghz,
since AO-40's heyday. Going to get my old toys back out this summer.
This info will help stir those brain cells back up.

Alas, my search is back on again for a service manual (not the instruction
manual, which does have
some technical info, but is not comprehensive) for the Icom IC-471A. I do have
the instruction manual,
as well as a schematic. Thanks again to all who helped previously, and thanks
in advance
That thought has crossed my mind (that one never existsed)- I heard or read
somewhere that there was once a service
manual that covered both the 271 and 471, but I've never seen it. Will keep
looking though. Thanks!

I've heard/read about OSCARs I II having their antennas deploy after
separation from
the Agena B, but from all the photos I have seen, it shows a fixed antenna.
There is
even a photo of an AF specialist installing OSCAR I into the payload bay, and
this photo shows
the antenna fully deployed.
A bit of a correction/addition to my earlier email. Don Stoner, W6TNS (sk)
described
the antenna of OSCAR I in a Feb 1962 article in CQ:
The cover of the package contained a fixture for the 1/4 wave monopole which
used the case as a counterpoise. The antenna was secured to the cover until

I think so, but as I recall we were limited to a total of 10. Not
surprising as the process looked pretty manual. They were photocopies of

Great stuff, Mark. I'm an old, dusty assembler, and later a C programmer.
Used to program for fun,
then for profit, then after a few years of life I looked around and the art had
snuck ahead of me.
I used to hack up the PREDICT code for my own devious purposes, and just to
