This is a bug fix release to FoxTelem. If you have been seeing issues then
upgrade to this new version.
Primarily it addresses the following:
* Crashes seen at run time
* Issue with DDE transmission to SatPC32 which can hang FoxTelem or another
program using DDE
* Some minor issues with HuskySat graphs and display
It is available as usual here:
http://amsat.us/FoxTelem/windows/
http://amsat.us/FoxTelem/linux/
http://amsat.us/FoxTelem/mac/
Thanks to all who reported bugs and issues. Keep them coming. Let me know
if you see any other issues.

Thank You for this Update Chris,
???? Just had AO-91, 92 and 95 pass over and W worked fine, I also
noticed that a quirk where version R running would cause other programs
in task manager to show increased CPU utilization on windows 10 is gone
and W also runs at about half the CPU utilization that R did.
Well Done 73

Thanks for the comments Kevin.
I had a slight issue with my migration script though. The version you
download should say "12 Dec 2019" next to the version. If it says the 6
Dec 2019 then it missed the last commit from my build. It's not a major
change. If you see issues you should download it again and replace the jar
file.

Jeff,
I haven't seen any replies so I'll give you my input.
These are excellent and flexible controllers.? I have one here on my EME
array which uses the M2 MT-3000 positioners and have installed them at
several university ground stations as well as the Air Force Academy.? In
those places they control various antennas from 4 meter dishes to V/U
Yagi arrays. Tech support is excellent.? The user guide is
comprehensive.? The setup software utility is easy to use.
One thing the Green Heron will do is always count the pulses from the
rotor motors even when you are sending it rapid commands over the
computer link.? We have had problems with other control boxes missing
pulses and therefore getting out of calibration with the antenna when
there is constant serial port traffic. The GH will always capture every
pulse and will stay calibrated. (It will also work with voltage sense
feedback from motors like the G5500). The USB interface eliminates
intermediate boxes.
Note that you will want to tell GH what rotor and interface you will use
the controller with so it can be configured before they send it to you.
These are not cheap.? But we have had no problems with any of eight or
so we have worked with.? One, installed at U Alaska Fairbanks, has been
operating autonomously or via remote connection for nearly two years
without a problem.
I'd highly recommend them.

Just a note that Fox-in-a-box orders from the AMSAT Store after December
13, 12:01 UTC (that is, by the time you see this) will also ship with
FoxTelem V1.08w. The FIAB download directory has not yet been upgraded,
but a downloaded SD card as well as existing cards are very easy to
upgrade. Please see previous articles here and in the ANS for how to do it.

Apparently it is not easy for18 SPCSto determine accurate TLE sets
for the PocketQubes in the 2019-084 launch. This is understandable,
given their small size of only 5 cm.
Therefore I determined the TLE sets for ATL 1 (44830) and SMOG-P (44832)
myself, using accurate doppler measurements. These should (initially) be
accurate within a few seconds.

Although we have lost the PSAT-2 VHF downlink, the UHF PSK31 and SSTV
camera are still on 435.350. We have been asked by authorities to confirm
that PSAT2 is correctly catalogued as 44354? (I believe it is)
Similarly, USNAP1 is still beaconing once a minute on 145.825. They are
asking if it could be 44357 (OBJECT U) instead of 44355
Having moved out of our lab/groud station of 27 years we have no antennas
and cannot easily do this until the spring.

All this time, I've been collecting and reporting telemetry from JY1 and I
just noticed that it is also sending images (at least some times). Some
info please:
1. Can the program be told to autosave images.
(Looks like it does in AppData subdirectory)
2. Is JY1 always sending down image data?
3. Do either AO-73 or EO-88 do the same thing?
I thought image was a special mode only turned on now and then. Perhaps
that is true and I just got lucky bumbling around this morning!
Tnx any info. 73, N0AN

P.S. The SSTV is automatic once every 2 minutes or 4 minutes depending on
Energy levels. But ONLY in spacecraft daylight.
The PSK31 audio downlink does not activate unless someone is TXing PSK31 on
the ten meter uplink. That is around 29.4815
So I guess there is nothing to hear unless we get some people on the ten
meter uplink. (this is unlike PSAT which has an uplink in the NORMAL
terrestrial PSK31 frequency and there is usually someone on (unknowingly
being relayed). Not so for PSAT2 which has to have someone transmitting
first. But if you do, you get the full transponder for the full pass as
long as you keep transmitting. Others can join you a few dozen Hz away and
have a multi-way chat.
