As a follow-up to this thread, I would like to thank all who replied to my
questions
and helped me along the way. By following the instructions given, I now have
both Icom?s running together with
SatPC32?..how sweet !!!! Sure beats using the ?ol overlay plotter?wasn?t it
an Oscarlator ?
Thanks again and it?s time to finish my Satellite station with some
antennas (cp)
and get on the air ;0) I?ve already completed the WRAPS-II az/el rotator
system.

The Perseid meteor shower peak is predicted to occur between August 11
to 13. There are a few pre-peak pings already audible. The activity
should increase over the next several days.
Web streaming of the Perseid is on-line at:
http://spaceweatherradio.com/
Quoting from their web page here is how they do it now:
The US Air Force Space Surveillance Radar has been shut down, but
we're still recording meteor echoes. How do we do it? Radio engineer
Stan Nelson uses a Yagi antenna in New Mexico to detect 54 MHz TV
signals reflected from meteor trails. When a meteor passes over his
observatory--ping!--there is an echo.

Many stations, who have their FUNcube Dongle SDR setup to automatically
receive telemetry signals from FUNcube-1, will have noticed that they are
now also seeing the telemetry from the FUNcube-2 sub-system which is flying
on-board the UKube-1 CubeSat. This is part of the commissioning program for
UKube-1 which is presently underway.

If true, this would provide the first SDR with output on 6 Meters, 2
Meters, 222, 432, and 1.2 GHz. This would be a real game-changer for VHF
weak signal operators, and provide enough drive for most amps. Can't
wait to learn more about this product.

Did you look at the Blade RF?
http://nuand.com
With available downconverter and full duplex! It is already a game changer
and being used.
Also, the HackRF is shipping now.

Good evening,
I will be on AO-73 tonight at around 02:58Z, calling CQ at around
145.965 MHz. These passes usually don't have much, if any, activity
and I'd like to drum up a bit more.
The satellite will enter sunlight at 03:05:45, giving about 7 minutes
of transponder time here in Washington, DC. I will be operating off a
south facing balcony, so I will probably lose the satellite about 30
seconds before the transponder shuts off.
Tips for working AO-73:
-Do not use computer control, the transponder frequencies are not
stable and this will only result in frustration. Besides, manual
Doppler control is much more fun than letting the computer do all the
work!
-I usually start a pass by trying to find myself come into the top
edge of the passband (145.970 MHz). To do this, I usually start
transmitting around 435.130 MHz and tuning up slowly until I can hear
myself enter the passband. Then I can move around the transponder
easily. Remember to tune your uplink to maintain an constant downlink
frequency (the opposite of FO-29).
-Keep power output down. The transponder has a very sensitive receiver
and a very active AGC circuit. Excessive uplink power will not make
your signal louder - it will only reduce that available for others on
the transponder. With a clear view of the horizon, 5 watts to an Arrow
or Elk is plenty for horizon to horizon coverage. Very slightly more
might be necessary if you are beaming through trees or other
obstructions, but try to keep power to 25-40 watts ERP.
Hope to hear you on this evening!

Worked W5PFG and CO6CBF on the pass. Satellite sounded great as it
always does. With my Arrow and 2 FT-817s, I was able to locate my
downlink with the satellite at about 1.5 degrees of elevation. My
signal was plenty loud at about 2.5 degrees.

Stefan,
Yes, I've tracked the Blade RF closely...but I think you've answered
your own question. To use the device on 2 Meters or lower, you need
downconverters...and the output power level is too low to drive most
amps. Basically, it's an engineer's tool, but not well suited for
operators. Ditto for the HackRF.
The Cross Country Sentry promises to drive brick amplifiers without
intermediate stages, and excellent performance on all the amateur VHF
bands due to bandpass filtering. To be a true "game changer", a product
must not only be a technical marvel, but it must be popular in the
marketplace. It remains to be seen if any of these products will reach
that standard, but an inexpensive all-in-one VHF/UHF SDR transceiver
would certainly be in demand.
Time will tell.
