Steve,
Here is what I used:
NO-84,435347.7,28119.74,FM,USB,NOR,0,0,PSK31
Essentially what you are using, with the fine tuning of the numbers insuring
the uplink places the
signal exactly where it is supposed to be in the downlink passband, and the
downlink is centered. It
has been several months since I have tried NO-84, and I recall there was
some very slight day-to-day
drift.
<I've not made any other entries anywhere else. One issue...My IC-9100
<appears to be tuning Ok, but it ends up at 435.340/28.120 each time. not
<centered on 435.350 like the doppler.sqf file calls out.
Not sure what you mean by "ends up?" At LOS?
73s,
Alan

Hi Folks,
I have just switched AO-73/FUNcube into continuous transponder mode for
the weekend.
Plan is, as usual to switch back to autonomous mode on Sunday pm UTC
Enjoy the transponder and have FUN!!

Message-ID: <20160304215711.8342B88AF@xxxxxxxxxx.xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"; format=flowed
Salvatore Bologna of Helical Technologies in Rockledge
Florida had his new quadrifilar uhf antenna at Orlando
Hamcation. Sal wanted to test it on my satellite demo
station to see how it performed against the Arrow antenna
we were using.
We set up an A/B switch on the UHF port of the IC910H so
we could switch between their quadrifilar and the Arrow
on a tripod. We tried it on FO-29 and SO-50 during
two passes. The results were not surprising. The Arrow
always did better but the quad did hear stations. They were
just down a few db depending on the elevation.
Their quad is housed in a pvc tube and was on a 10' pvc
mast. It is very stealthy and that's a nice characteristic
of the antenna. If you live in antenna restricted area,
this antenna will pass for a vent pipe or as part of a flagpole.
But there is no way this antenna can perform as well as a 7 el
beam adjusted for proper polarity. But it does work and
you can hear stations on FO-29. SO-50 is a much weaker
bird and signals were weak on the quad. But you could
hear stations and you could make contacts.
There is a video of my demo station at Hamcation on youtube.com
You can see Sal sitting in back of the radio, flipping the
A/B antenna switch during the passes. The audio is not perfect
so it may be hard to hear the difference between the antennas.
They are working on a vhf version. Their website is
helicomtech.com
Antenna selection depends on many different factors. You
write down your objectives and then consider your
constraints when making your decision to purchase. Every
case may be a little different.

Hi everyone again,
Here is the follow up on my High School's Balloon launch, it was a success,
and we had a lot of fun with the launch. Unfortunately APRS did not ever
obtain a GPS lock. It only transmitted temperature, humidity, and pressure,
with location at (0.000, 0,000), however we were asked to fly just our APRS
on the next EOSS launch as part of the STEM outreach, so we will get the
GPS portion of the APRS payload fixed up by then. Our other two payloads
worked great, however.
I created a webpage with all of the details of the launch right here
amsatnet.info/#balloon
Here is a youtube video of the launch
https://www.youtube.com/watch?v=adDF-m4ecnA
I am still analyzing the crazy amounts of data for our Field Mill payload,
so that information is not up yet.
I would like to thank the people who donated! This launch would not have
been possible without their support.

The live stream from the school starts in 10 minutes from this email
10:00UTC and the contact is 50 minutes later 10:53UTC. We don't expect
live video from the HAMTV system but you never know. There is a great

Cool, always good to have three beacons. My group, Arizona Near Space
Research uses three beacons as well.
How high did you get? Our last flight at the Yuma hamfest reached 99,600 feet.
Good luck on your next flight. Please share your telemetry results once you
finish reducing the data.

Message-ID: <20160305185707.GA745@xxxxxx.xxxxxx.xx>
Content-Type: text/plain; charset=us-ascii
I listened to the ARISS contact with England (Wales, to be precise) this
morning. I followed the preparations via the principia live stream but I
went outside with my arrow antenna for the contact itself.
Elevation at my location was not too high (maximum of 46 degrees) which was
a bit of a problem between the houses. I held up my arrow above my head for
maximum reception but that got tiring real quick.
So I heard the answers to about 3 or 4 questions. But it is still quite
special to hear an astronaut talk live.
On the principia live stream I followed the rest of the event. It's good to
see the contact is much, much more than just 10 minutes of Q and A. There
was a lot of explanation about the ISS, the work Tim Peake does, the
influence of space on the human body. Including bits where the scientists
say "we don't know why this happens, we're still researching it".
The ARISS program and the Tim Peake mission must be a boost for STEM
education and amateur radio.

Does anyone remember how to make a High level frequency doubler? I need
some energy on 902 MHz, and wonder about just blasting some diodes with a
451 MHz transmitter? (followed of course by a filter)...
Seems like a full wave rectifier would give a strong 2X frequency component?
I wonder if 1N4005's would do? At 50W input the capacitance per diode is
around 1 pF
