In theory, it would sort of work for receive. But don't try to TX through the
array as it would create interference to other users on adjacent frequencies
on TX (NOT GOOD).
Now as far as the RX application;
If you think about it those adjacent frequency users would also mix with the
switching frequency and become interferers to your desired RX frequency.
Interesting idea if it could be made to work.
However if you have a second receiver, no reason you could not have a
diversity RX setup to select best polarization.
Hi all,
Has anyone ever considered the possibilty of using PIN diodes and a free
running square wave oscillator to electronically switch between RHCP
and LHCP?
The switching frequency would have to be high enough so as to not
introduce
a tone to the signal.
Just a thought I have had for awhile.

As far as QSL cards, yes many people send them. When I was active, I
would QSL to any station that I had not talked to before, or any time
upon request. I normally just sent the postcard, and I did have special
QSL cards printed for satellite use with a custom set of fields that
made more sense for satellite work. See
http://home.earthlink.net/~k6ccc/QSL.html for my cards. If the other
station was on an expedition (for example a rare grid), I would send an
SASE as I knew they had gone to special expense to activate a grid for
the community so I would pay for the postage both ways.
For the voice protocol on the busy birds, the best way is to listen for
a couple passes and you'll pick it up pretty quickly. The short answer
is keep it VERY SHORT and FAST. When the birds are not busy, you can
actually chat. Back a few years ago when I was active, there were
northbound passes on UO-14 in the late evening that were well off the
Pacific coast of the USA and the footprint just skirted the west coast.
As I am in the Los Angeles area I often got on and there was only one or
two other stations for the first one to three minutes of my pass. We
would often chat for fun that way. As the bird went farther north,
there were more people and it was back to the SHORT and FAST operating mode.

Hello all,
for those interested in further results with two lindenblad antennas
(see my earlier post for a description of the setup), I had the
opportunity to already test a couple of passes of the ISS configured
as V/U repeater.
The received signal is very strong already an S9 from 2 degrees of
elevation and peaks to S9+40 when the ISS is higher than about 14
degrees. Usually there can be some deep fades during the pass. The
transponder is accessible if not too many stations are txing at the
same time. I couldn't complete any QSO in a 80 degrees (max) pass
(many european stations heard), but completed two QSO in a 30 degrees
pass over south europe. Unfortunately the frequency pair isn't very
friendly for the FT-847, it receives its own spurii or harmonic when
the doppler correction hits a certain frequency pair at the second
half of a pass.
On the linear sats (VO-52/FO-29) I'm able to complete a mean of one CW
QSO per pass, AO-07 is much more difficult because my own signal is
very low and other signals are greatly frequency modulated and thus
very difficult to decode (for my poor cw skills).
Again things would be much easier with preamplifiers under both
antennas, but I think only CW QSO would be possible anyway (but
probably a lot easier than now).

Tim,
Sort of like voting. Actually both receivers are receiving full
time. The computer combines this information and the signals
received to both display the effective polarization angle and produce
a maximized signal output. An alternative that is available with
Winrad and Linrad is to output each audio stream to the right and
left ear of a stereo headset with the result your ears and brain
process the effect. Polarization changes produce a stereo effect, as
it were. This is currnently being done be eme stations!
HF stations have long done diversity reception by use of two recevers
and antennas separated by some arbitrary amount. When done with FM
repeaters the repeater compares all received signals and choses
(votes) for the best signal to repeat. This is largely an analog system.
For eme and possibly satellite application audio is digitized and
processing is done in the computer with audio reconverted from the system.

Joe,
Makes a good point about this as appropriate as a receive-only system.
To answer Rod: Pin diode antenna switching has
been done by radio astronomers for years in what
is called a Dicke Receiver. They switch at audio
rates between the antenna and a noise reference
source to track minute gain variations in the receiver.
The basic problem with your approach is that half
of the time you will be in the wrong
polarization, leading to a 3-dB overall reduction
in sensitivity. The approach I outlined with
dual receivers eliminates this. But functionally
a pin diode can be used for switching and
controlled by a square wave at any desired rate
up to the limits of the pin diodes response.
For a transmission system that will adjust to
polarization changes. The simplest is merely a
coax switch to chose the best polarity at the
time. A more advanced system would use
programmable phase shifters to accomplish exactly
what polarization is desired (if you have a gov't budget, that is).
My bottom-line question to all these schemes is
how you are going to determine what the best
polarization to chose? This is not a simple
exercise in orbital mechanics and
solid-geometry. The Ionosphere adds Faraday
rotation at random. If you can predict Faraday
then you probably will make a fortune in weather predictions, too! ;-)

Hi Tom,
QSL cards are handled about the same as with HF; some operators send them,
others do not. It depends on what they're after. (But please, if you do
receive one, send one back!)
On the busy FM birds (AO-51, especially), the trick is timing. You need to be
able to slip your call sign into a gap in the exchange. If your call is
short, phonetics are best, but most of the time the window is short, so just
try to say it normally, clearly and quickly. If there is someone specifically
you want to contact, say their call sign and then yours. Saying just your
call is equivalent to a CQ; saying CQ is not expected on the busy FM birds.
Again, timing is key, and be brief. When you venture to the SSB/CW satellites
(FO-29, AO-07, VO-52), others need to find you, so stringing out a couple of
"CQ Satellite" calls is appropriate. You will be able to hear someone coming
back to you, because there's no capture effect; both signals will be heard.
Listen for a few passes to get the feel of it, and then try on one of the late
night passes when it's not so congested. I recall a few passes on UO-14 (RIP)
around midnight where there were just three of us on, and it was just like a
round-table on our local repeater.
Good luck!

Hi Tom:
?
You could look into using something like eQsl (www.eqsl.cc) which is pretty
cool. Also, get yourself a computer logging program (N3FLP's amateur contact
log)?that will interface with eQsl. Pretty neat, although there is a learning
curve associated with eQsl.
?
The exchage is different on the FM sats vs the others (AO-7, FO-29, AO-16)
where you can actually have a short conversation. listen in for a bit before
you try to work anyone. On the FM birds, you have to be?pretty quick, as
well...people don't wait to make calls to others. The FM birds are a world of
their own.
?
Enjoy, and see you on the birds!!

Just keep in mind that if you use eQSL, the ARRL and AMSAT do not
accept them for awards. But, eQSL has many of their own awards.
