I've also heard a very strong downlink of my signal on a couple of
occasions, but not had any replies. I am on the East Coast of the US in
Brooklyn.
That said, I get very deep fades with AO-73. I think the antennae are in
the x-y plane and are dipoles. They are therefore rotating as the
satellite rotates about Z. If you are using an arrow antenna, or similar,
then you get a deep null periodically and you can completely loose your
signal if you are not careful. Does a CP antenna help with this? Can
anyone using CP confirm?
I understand AO-73 rotates about once a minute, or once every two minutes.
So you should have a null every 30 seconds or so but it _seems_ worse than
that and it's enough to throw you off, especially if you have struggled to
find your signal in the narrow downlink in the first place.
Then of course it goes into sunlight and your signal pops out of
existence....
All in all, a tricky sat to work. I'm looking forward to my first contact
through it.

hello-after spending over a half hour on hold waiting for a Yaesu tech to

Five days into it's eclipse season, AO-7 is operating very well.
Strong Mode B signals on the last pass over eastern North America. I
worked PV8DX, N8RO, KV1J (his first AO-7 QSO), and KB1RVT. My 25 watts
ERP was plenty until the satellite started going behind the trees to
the north.
Hope to hear everyone on the next pass in just under an hour. All of
North America will be comfortably in the footprint.

Hello Chris.
I listen daily to AO-73 to gather the telemetry data.
I use a 12 elements cross yagi and can switch between left CP or right CP.
At low elevations (between 0 and 10 degrees) I also suffer from deep
fadings where the signal is in the noise and then slowly coming back.

Eric.

Yes, that is certainly nice that they included those payloads as a favor!
Another thing is that some of the ISIS transceivers used in many of
the CubeSats that are on the drawing board or have been launched use
the ISIS transceiver that includes a loopback mode, which can be used
as a single channel transponder. It'd be great if a few of them could
turn on the loopback mode and open them up for use by the amateur
community when they complete their missions.

Hi All,
Yes the antennas are dipoles and the spacecraft is slowly rotating around
the Z axis on which they are mounted. Therefore you can be in a null when
one end of the dipole is end on or nearly end on to your QTH, generally
circular polarisation at your station will not solve this but they will make
some improvement to the received signal strength at other times!
The speed of rotation is changing by the day. The current status can be seen
here:

Many thanks for your on going support of FUNcube-1.

Good evening,
On the last pass of FO-29 over the United States, there were a couple
of stations tuning and one that started calling CQ in CW right on the
center frequency.
HK3Z was already calling CQ on that frequency when the satellite rose
over North America. I did work him, but several others could have as
well if not for the QRM. Please go up or down a ways to find your
signal so you are out of the way. Remember that FO-29's passband is
100 kHz wide - 435.800 MHz to 435.900 MHz. There's more than enough
room for everyone. If I decide to call CQ, I generally start calling
10-15 kHz above center and move down only if nobody is responding
there.
Now, there was also non-ham FM QRM on the center frequency, but that's
a different story and there's not much we can do about that.

Yes, CP antennas definitely help, both on the up and down links. In my
experience it doesn't matter much which direction (left or right hand), just
that they're circular. Both of mine are, and I found the satellite's signal
to be really consistant across the pass.

Hi Bill,
As the owner of a Yaesu FT736r (another one-direction CAT rig), I've found
it's easiest to let the computer run the antenna rotor, but leave the knobs
to my own nimble fingers. For FM, certainly let the computer run the rig.
For SSB I make a lot of use of the tracking knob - which links the up and
down links inversely to scan the band to find a QSO, then adjust the upper
band's frequency for Doppler from there. Finding myself just takes a little
practice, and a few dits.
As for the software, I use GPredict for pass prediction and "eye candy"
during the pass. My rotor controller is home brewed, as is the CAT client,
so that's not going to help you, but I believe the recent versions of
GPredict / HamLib will drive many radios and commercial rotors.
Good luck,
Greg. KO6TH

Bob,
I have a 5400 but have had the same problem. We used to buy them from Yaesu
at a premium. In defense of Yaesu they are not in the parts business...
The good news is! - My experience is they can almost always be repaired!
There is a little wire running to the center of the pot. This wire actually
gets twisted as the pot turns and eventually fails. It will often look
mechanically okay, but it will fail very close to the solder joint. Replace
the wire, good for several more years.
I hope this helps, 73,
Joe kk0sd

Thanks to the many for my el rotor problem. Took down, took apart-position
pot failure-I could (maybe) make it work but since I have everything down I
may as well replace it. Where's a good source for said pot?

Perhaps I missed this information earlier someplace else, but reading in the
March/April 2014 AMSAT Journal just received yesterday, I note in Barry
Baines column, Apogee View, that the launch date for the ELaNa-12 group of
satellites, which includes Fox-1, has been re-scheduled from December, 2014
to August 2015 due to changing govermental priorities.?Barry points out,
that while AMSAT is dissappointed in the launch schedule slippage, it will
result in more time to to complete and test the satellite prior to delivery
and allow greater confidence in the spacecraft's readiness.
Reading further, it also appears the possibility exists FOX-1 might get
moved to the ELaNa-11 mission currently scheduled for March/April 2015.
ELaNa-11 is projected for a slightly different orbit, resulting in a lower
apogee and shorter orbital life.
More news may be available at the AMSAT forum in Dayton later this month.
