Re: Apartment Dwellers

Hello Margaret.

Hahahahaha.  I'm not sure what the neighbours here think when I wander around
waving a couple of antennas as though I'm divining water. :-)

That does greatly reduce the signal, though today, we actually managed some
reasonable signals at a hobby show while beaming into the side of a church.

I didn't worry about the checksums.  Basically, I put them into Winorb
manually, then dumped the keps to disk, and they came out in NASA format.

OK, maybe my situation has some parallels.  However, I do have the luxuary of
having a tri band vertical on the roof.  Basically, for SO-35, UO-14, etc, I
run portable.  The lower gain of the antennas is offset by the greater feedline
losses in the shack, so portable works well.  I find I can usually get in with
a couple of watts.

Now, one can go in one of 2 directions.  Firstly, try a more difficult "bird".
Here, I chose RS-13.  I have 2m SSB which I can run into the vertical.  I can
also run a second (10m) vertical on a mag mount on the car for the downlink.
This setup enables me to work Mode A, though only RS-13 has sufficient signal
for this setup.  25 W into the vertical gives me a dignal a few dB down on the
beacon.  Another option, if you can run portable beams is FO-20 and FO-29,
which run Mode J (SSB/CW).

The other path to take (warning, the neighbours will _really_ think you've
flipped!) is to try operating from more difficult situations - using less
power, antennas, or from some place people don't expect a satellite to be
worked from.  My classic example is a tram or train! :-)  I've worked SO-35
that way, and intend to try the same with UO-14 one day (now that _will_ be
tough, UO-14 is sometimes hard enough to work in the open with a 1/2 wave).

Good luck. :-)
