I did some testing last night. To be clear, I have a FT-847
that has single direction CAT.
Rigs with serial numbers later than 8G05xxxx have
bi-directional, rigs younger are likely
to have single (Yaesu did go back and offer uProc
replacements for a time, so if a rig is
older, it may still do bi-directional CAT).
More here:
http://www.supercontrol.de/cat/ft847faq/page4.htm#catcontrol
I installed and tried Gpredict on Ubuntu. The software and
the rig won't link up for more than a few
seconds, so there must be some bi-directional handshaking,
and then a timeout. I ruled out my
cable, etc, by using the Grig executable that comes with
Hamlib. With Grig I can push changes to the rig,
but no response to anything I do on the rig. More here:
http://www.neodux.com/read/HOWTO:_Configure_Hamlib_for_Linux_Hams_-_Part_2
So then I tried SatPC32 on a WinXP machine. Actually, "out
of the box", it works somewhat...
changing birds will correctly set up both VFOs and the
modes. However, driving the VFO from the
software, or letting the doppler correction take over, only
effects the main VFO on my rig,
not the sub-VFO.
Greg suggested that I let the PC control the rotor instead,
and manually adjust doppler on the rig.
Probably a good suggestion, and something I had no problem
doing in the AO-40 days,
but I won't have a computer controlled rotator, a different
FT847, or the skill to swap out a
surface mount quad flatpack (the processor in the FT847 than
needs to be swapped to get
bidirectional) by FD; I'll take what automation I can get.
I'll continue playing.

Hi Nick,
You did not miss anything, the information you read in the Journal is as
new to you as it is to us. It was learned at the time Barry was writing
his Apogee View in March but due to Tony's illness and passing the
Journal issue was delayed a week or two in order to include the
information about Tony. That then, slightly delayed the delivery of
this news about the launch delay.
I will talk about it at Dayton. See you there!
73,

ELaNa-11 is projected for a slightly different orbit, resulting in a lower
apogee and shorter orbital life.

My thoughts regarding the two launch possibilities:
I hope that, if given the choice, that AMSAT sticks with ELaNa-12. The
11 year orbit and 780 km apogee is much better than an apogee in the
600 km range and a 6.5 year orbital life. Given that Fox-1 is the
first amateur satellite designed for it's batteries to eventually die,
we should give it the opportunity! Also, since it's so hard to get a
launch these days, it's best that when we do get a launch, it can stay
in orbit for as long as possible.
And for everyone waiting for a new FM satellite who is disappointed by
the delay: The good news is that we should get a new Mode U/V FM
satellite at approximately the same time Fox-1 was supposed to launch.
The QB50p2 satellite is scheduled for launch on June 19th with an
AMSAT-F U/V FM transponder on board. After six months, the satellite
is supposed to be turned over for amateur use, if all goes well.
Regardless of what happens, best of luck to everyone working on the
Fox program. I am making a small recurring monthly contribution to the
program and I hope that everyone who is able to do so provides
whatever support they can.

Bill,
As you know, manual Doppler correction is going to be a quite a bit
different than on AO-40, but still relatively simple with practice.
Always adjust the higher of the two frequencies and leave the lower
frequency fixed as far as possible (slight corrections may be needed
at times, of course, depending on how the person you are in QSO with
is tuning).
Be sure to get on the sats and practice before Field Day. This goes
for everyone who rarely gets on the satellites at other times!
Perhaps the first or second weekend in June should be a practice
session for Field Day to make sure that the kinks are worked out
before the live event.

I've been working on a very large antenna project. To day I will solder my
last two connector's. Then a little preflight inspection. I hope this works
I've been working on the on and off all winter.
If the antennas work it's off to my transverters and flex radios putting
them on the birds.

I know I'm being picky here but it's the first FM voice CubeSat to be
designed for operation after battery failure. DO-64 (Delfi-C3) has always
been operating without batteries and FUNcube-1 is designed to operate after
battery failure.
Sadly launch slips are a fact of life, even if you're paying top dollar as
primary payload you can still have launch slips. Any launch dates quoted are
the earliest possible date but actual launch may be many months or in some
cases even years later.

One hard and fast rule in the space launch industry:
Everyone remembers a launch failure, no one will remember a launch delay.
Delays suck, it's a hell of a lot better than blowing up. The launch
industry is largely binary, you either fully succeed or fail. This is at
least the perspective of the vehicle providing the ride :D

Hi Paul,
From the Fox-1 Team, thanks for the support and well wishes. We're
working hard to fulfill everyone's expectations!
I will have additional information about the launch opportunities, at
the AMSAT forum in Dayton.
