If you can avoid using the Baofeng on 2m transmit, things will probably
work better, as several studies have indicated the UV-5R often fails 3rd
harmonic suppression requirements -- this would tend to desense the 70cm
RX, especially on a shared boom antenna like the arrow.
That would be an issue for SO-50, but not Fox-1.

between radios anyway. Those files are not like the config files

The KG-UV8D is not capable of working SO-50 full-duplex. When you
transmit on 2m, the 70cm receiver is desensed. You won't hear
the satellite again until you stop transmitting. The radio is
capable of working AO-85 full-duplex. I wrote about this on the
AMSAT-BB list a year ago, and you can see that message at:
http://amsat.org/pipermail/amsat-bb/2015-November/056254.html
I do not use memory channels for working AO-85. I use the two
VFOs, open the squelch all the way for the receive VFO, and
transmit from the other VFO. That link has some key settings
I used with that radio.
You can program a group of memory channels to work SO-50 half-
duplex. A guide for that is available from AMSAT's Station and
Operating Hints page at:
http://www.amsat.org/?page_id=2144
(look for the document "Operating FM Satellites")
Or use another HT with your KG-UV8D, so you can transmit from one
radio while listening to the other radio for full-duplex operation.
If you want to use an HT to work both AO-85 and SO-50 full-duplex,
there is only one option currently in production: Kenwood TH-D72A.
The new TH-D74A is not capable of full-duplex operation for any FM
satellite. Wouxun's KG-UV9D, like the KG-UV8D, is capable of working
AO-85 full-duplex, but not SO-50. Along with the KG-UV8D, I wrote
about a few other Chinese-made HTs and tried using them to work
FM satellites full-duplex. They could do that with AO-85, but not
SO-50. You can get to the messages covering the other radios I

Gerald,
I can confirm WD9EWK's findings on the Woxun radios. I used to own a UV8D
and now a UV9D. These are pretty decent little rigs for working AO-85 in
full duplex. I haven't done much on Fox with an Arrow but it works great
with my Elk.
I can also confirm that these rigs won't do full duplex on SO-50 because of
desense. I've tried several configurations including stock Arrow and Elk
antennas. I also tried again after I cut down my Arrow into a 2x4 element. I
seen this done by W5PFG and decided to give it shot. It did not help
anything on my UV9D but it's worth noting that it eliminated the desense I
was getting on my FT-8900.
One thing I do with SO-50 on these rigs is to leave the VFO I'm using for
downlink as main so you can easily adjust for Doppler. I then use the
secondary PTT function to key up the other VFO set for uplink. This will
keep you from having to switch back and forth between VFOs to adjust RX and
jump back for TX. On AO-85 I've only ever had to adjust for Doppler on the
uplink so I just leave it as main.
73!

Hi John
The CAS-2T has just passed over Brazil and the beacon still are working ,
very strong .
The problem in my opinion looks that the sat reset before finish the
complete set of caracteres , I mean , sometimes it send CASI or CASE , even
CAS only . Since the number 2 must be the next letter , I think it can not
TX the entire "2" (. . _ _ _ )
Just my guess.

Hi!
I will have an AMSAT booth at the Superstition Amateur Radio Club's
"Superstition Superfest" hamfest on Saturday morning, 3 December
2016. The hamfest will be at Mesa Community College, between Southern
Avenue and US-60 exit 177 along Dobson Road in Mesa, Arizona. The
hamfest is normally in the southwest parking lot along Dobson Road,
next to the US-60 freeway. The hamfest officially starts at 8am (1500
UTC), but I am sure there will be buyers and sellers out there at
least a couple of hours before that time. More information about the
hamfest is available at:
https://www.superstitionsuperfest.org/
WD9EWK will be on various satellite passes during the hamfest - most
likely in the morning, and maybe into the afternoon if there are
still crowds walking around the hamfest. If you hear WD9EWK on the
air Saturday, please call and be a part of the demonstrations. All
QSOs will be uploaded to Logbook of the World after the hamfest.
Please e-mail me directly with QSO details if you would like to
receive a QSL card.
During the hamfest, I'll tweet updates regarding satellite passes I
plan on working, along with photos from the hamfest. These will be
visible on my @xxxxxx Twitter feed, or in a web browser at:

Solve NASA's Space Poop Problem, Win $30,000
http://tinyurl.com/hcfovgk
Butt, Really.
<http://nasa.gov/> NASA is doing everything it can to keep its hands
clean-of poop. NASA has launched <https://herox.com/SpacePoop> "The Space
Poop" challenge for participants to invent a hands-free system that routes
and collects waste away from the astronaut's body for up to six days.
How do you deal with human waste when you're trapped in a space suit for up
to a week? That's what they're asking you. Inventors have until December 20,
2016, to submit their best "space poop" ideas for the chance to win $30,000.
During spaceflight astronauts can be in their suits for more than 10 hours
at a time. And, with NASA's plans to send humans deeper into space, future
missions will require the advancement of new technology to keep the
astronauts alive and well. And, shall we say, clean.
Currently crews wear an absorbent diaper, but these will not be suitable for
flights longer than a day. While it goes without saying that nobody would
want to wear a diaper for a week, the issue is more than a matter of
cleanliness, it's a matter of life or death.
It is vital that the waste needs to be treated otherwise it could harm or
even kill the astronaut, especially if infection sets in.
NASA said it aims to test the winning ideas in the next year and roll out
successful systems in the next three.

I'm a software engineer that works with a bunch of electrical engineers
on some radar stuff. So I've been interested in learning more about the
electronics, signal processing and related matters. I'm also interested
in and fairly knowledgeable about orbital things already, so it seems
like amsats are a natural fit.
I studied up and recently got my General, but I have basically no
equipment other than some SDR dongles and a Baofeng. I did manage to
cobble together a yagi that let me pull down both voice and data from a
couple satellites, by waving the antenna around in what I hoped was the
right direction. (I printed out the pass, but didn't and still don't
have a reliable way of tracking.)
What I want to do next is basically email myself over RF via space. I
know there's some store-and-forward sats, but that's about it.
I'd prefer to have an antenna that wouldn't need to track. I can limit
myself to passes over X deg (say 30) to get short ranges that don't need
high gain. But maybe the pass lengths won't be long enough to send and
receive in that time?
What I'm really looking for is tutorials. It's pretty easy to find ones
aimed at hams who don't know anything about satellites or
computers. It's hard to find ones for computer- and space-savvy people
who don't have a lot of practical experience with xmit/rcv.
