Hi all-
A new version of the TQSL config file was just updated. AO-85 is now listed.
Update your LOTW config file and you should see it.

Hello Steve,
The only hardware/SDR supported natively by Foxtelem 1.0 is FCDP or
FCDPplus.
For other SDRs, you have to use something like SDR#, HDSDR, SDR-Radio V2,
to decode the audio (FM,about 12-15kHz wide,audio filtering OFF); ouput
that audio to a virtual audio cable, then set up Foxtelem to use that
virtual audio cable as input. It works, both live and with recordings,
both slow and high speed.
I will copy AMSAT-BB since others will ask, too :)

Bob,
It seems unlikely that a small movement in the filter length would make
such a dramatic difference. It's possible it reduced the load on your CPU,
but that also seems unlikely. A slow computer usually misses audio first
because it can not keep up with the sound card. That is why we track
missed audio at the bottom of the window.
So this could have been a coincidence? But maybe not. We left the filter
controls on the program for just this sort of experimentation. So keep at
it!

I will pile on to Mark's reponse in case you want to use the other "IQ"
features of FoxTelem, such as capturing the RF Signal To Noise or the TCA.
If you use a program like HDSDR, then you can also feed the IQ audio to
FoxTelem rather than the decoded audio.

Hi!
Since the FUNcube Dongle Pro+ appears as a sound device to
Windows, you can have two programs connect to it at the
same time - provided they use the same LO/center
frequency and input bandwidth settings.
Chris confirmed via e-mail last night that the FoxTelem
software uses 192 kHz bandwidth from the FUNcube dongle.
With this information, I set HDSDR's LO frequency to be
145.960 MHz (a little below the 145.980 MHz downlink
frequency), and used this frequency as the center
frequency in FoxTelem. I set the Input Bandwidth in HDSDR
to be 192000, to match what FoxTelem expects to see. I
found that I had to start HDSDR first, and then start
FoxTelem, so both programs could access the dongle. Then
I didn't have to use a virtual audio cable (or, for some
Windows 7 and older PCs, the Stereo Mix audio device that
does the same thing) to pipe audio from HDSDR to FoxTelem.
Each program can then do what you want - in my case, HDSDR
wrote an RF recording, while FoxTelem decoded telemetry.
You can also mute the audio from either program, so you
aren't listening to the same audio from both programs
(HDSDR has a Mute button on the screen, and FoxTelem has
a Silence Speaker button).

One thing that bears repeating, or perhaps has not been said terribly
explicitly. The issue with decoding low speed data via the audio out of a
"regular radio" is the LOW frequencies not the high. You need to be sure
that the 9600 baud output does not have a low pass filter even if it can
pass light on the high end. We need down to only a few 10s of Hz. Some
radios work one way, some the other. Nearly all will filter out low
frequencies on the normal audio output. Check your manual. I have a
TS2000, but I don't remember the specs on 9600 baud out. I have used SDR
for my testing.
And another comment for another person re HDSDR and FoxTLM: I have a very
slow CPU in my shack. It can't deal with FoxTLM running its own SDR at
all. It *can* deal with HDSDR piping audio via Virtual Audio Cable to
FoxTLM running just in audio mode.

Subject: [amsat-bb] Fox-1A Telemetry Results using TS-2000
I've been reading this list for a while, decided it's about time I posted
something. I attempted to decode the Fox-1A telemetry on 2 passes over
Arizona today (approx. 0130 and 0300 UTC) using my Kenwood TS-2000 without
success. I configured it for 9600 packet operation, monitored the audio out
of ACC2 connector and could see over 20 Khz of audio bandwidth using
software based audio spectrum analyzer. Audio response looked good from 0
to 20 KHz so I thought I would be good to go. Nope. I fed audio into 2
different sound card devices - one being the RigBlastger Advantage set to 48
KHz sample rate and the other audio device being my Laptop's built in sound
card mic input set to 48K and 96K on different attempts. Audio levels were
adjusted so as not to be excessive and sounded clean when played back
through the speaker.
When attempting to decode, I could see a very nice eye pattern in the
telemetry decode software but the data square waves were pointy looking as
if some high frequency filtering was being applied to them. I' not
conclusively saying the TS-2000 won't work but I did everything right and
tested as thoroughly as possible prior to the actual satellite passes with
no success. I'll try again and see if I missed something and report back.
What DID work for me was decoding the signal via SDR. In this case It was
an RTL-SDR dongle in direct sampling mode connected to the 10.695 Mhz IF of
the TS-2000. HDSDR was used with output bandwidth set to 96 Khz. Audio was
piped to Fox telemetry decoder via VB Virtual Audio Cable software.

Drew, Quick question regarding the 67.hz tone.. Should I program a channel
with the tone at 435.170 or 435.180? It would seem that at AOS the bird will
hear it better at .170 vs. .180.
Am I over thinking this

All,
We will leave the transponder running until about 0000Z 10Oct. Feel free to
try it.
A couple of notes:
If the downlink isn't on, a few seconds of 67 Hz tone will turn it on.
Narrow FM may help with the downlink audio levels if you find it difficult
to hear.
You may find it takes a little more gain on the uplink than expected. I
encourage users to try their handheld yagis, remember to twist for polarity,
listening full duplex to peak your uplink.
During this time, the low speed data will still be active alongside your
voice downlink, so ground stations are encouraged to continue submitting
that to the server.

Ignoring the AFC on the uplink receiver, I would program 5 channels, from
