The old Cushcraft 144-20T CP antenna (Part of AOP-1) used Gamma Match on
both phased yagis, on a common boom. This wasn't the greatest antenna in
the world, it suffered precipitation static discharge because of the
Gamma Match being ungrounded, among other mechanical deficiencies. But
it did seem to have acceptable circularity, good directivity and plenty
of gain I suspect the problem may be in achieving identical phasing
between antennas. A phasing problem will affect circularity.

I have a basically brand new SSB Electronics UEK-3000 receiving converter
that converts 2400 MHz to 2404 MHz down to 144 MHz to 148 MHz. ?This
converter is made to mount as close to the antenna as possible. ?That is, it
is enclosed in a weatherproof case that has provisions for a "U" bolt to
hold the converter to the antenna mast, tower, etc.
The only Internet site that shows a price for these converters has right at
500 pounds which converts to a little over $780!
I have never actually used this converter. ?However, I have verified that it
is working properly using one of my HP signal generators that definitely
covers the frequencies of the converter.
The specification sheet, on the UEK-3000, is at:
http://www.ssb.de/ssb/files/en-3018_uek_3000.pdf
I am open to trades. ?Basically, I don't really need "anything"! ?However,
one can definitely "tickle my fancy" with offers from boat anchors to modern
equipment to components to antennas and so forth. ?As for a sale, remember,
these don't come cheap brand new. ?Reasonable offers considered.?Glen,

Hi Bob,
It could be that QB50p1 (EO-79) was using 2400 BPSK this afternoon.
There is some analysing going on after the transponder test.
The outcome will also tell something about the transponder operation
in the feature.

Updated PSAT Launch announcement:
Launch window begins at 1600z 20 May 2015, from Florida into a 55 degree
inclined orbit. We welcome radio amateurs worldwide to tune into the
downlinks and either IGate packets into the global APRS-IS system or email
to Bruninga@xxxx.xxx.
We expect first PSAT telemetry at 1839z over Sydney and New Zealand
followed 1910z pass over the USA. For any launch delay, slide these times
later. Launch can delay up to 2.5 hours or so.
Operations via PSAT or PSK31 are not authorized until on-orbit checkout is
complete (may take many,many days). Downlinks (one or more packets per
minute):
PSAT: 145.825 MHz 1200 baud AX.25 APRS ?
http://aprs.org/psat.html
BRICsat: 437.975 MHz 9600 baud AX.25 packet telemetry
USS Langley: 437.475 MHz 9600 baud AX.25 packet telemetry
PSK31: 435.350 MHz FM PSK31 telemetry
Further info will be posted when available on the PSAT page above.

Hi all,
DUCHIFAT1, the Israeli high school students 1U Cubesat is ready for first
public tests.
People with the ability to send Compressed APRS location packets are
invited to join the tests.
The satellite will collect these packets worldwide along its flight at
620km high orbit, and will downlink them from time to time over our ground
station in Herzliya/Israel.
Participants are kindly requested to register in advance in order to get
their packet identified on the map.
The packets successfully received will be displayed on a map in our
Internet site and QSL cards will be sent via Bureau to the stations
registered and recognized. (unfortunately, there is no way we can recognize
packets from unregistered stations because the packet is limited to 14
character at the satellite, so we assign two unique characters to every
registered station to enable us to identify them).
Registration can be done at www.h-space-lab.org
Also available in that site are operational information about the
satellite, and the following documents:
*Configuring TT4 Explanation.doc* - how to use the Byonics TinyTrak4 for
generating Compressed APRS packets
*Terms Of Use.doc* - terms and techniques for making the best use of the
satellite
There is also Ground station software available for download, written by
our students around ISIS space Demodulator software.
We hope many people will find it interesting and enjoyable,
good luck!

We?re now able to release a timeline of events for LightSail?s first day in
space.
The chart on LightSail mission Page assumes a liftoff of 10:45 a.m. EDT,
(14:45 UTC) at the start of the four-hour launch period. The actual window
has not yet been released.
We aren't sure when we'll hear from LightSail, but the first possible
opportunity comes three hours, 14 minutes after liftoff (17:40 UTC).
If you?re a member of the amateur radio community, YOU CAN HELP ! Our radio
frequency is 437.435 MHz. Email me any data you collect from LightSail,
including screenshots of the radio signal if you have them. I'll pass the
information on to our engineering team, and we'll recognize your
contribution on our blog.
LightSail's automated telemetry chirps start after antenna deployment and
continue throughout the mission. We?ll update our Mission Control Center to
show the spacecraft?s current position, including pass predictions for your
device?s current location (courtesy of N2YO.com).

Hi Greg,
Is the telemetry decoding software or code available for us to see/decode
the data and monitor the satellite? That would greatly help in getting
amateur radio operator support worldwide.
