I'm very curious about this, thanks for sharing the links.
Looks like the program adjusts the PSK modulation within the pass band of
the uplink, and at 10 meters, that would be relatively small.? It makes
sense, however would this work if SatPC32 manages the uplink ?
?
Secondly, I came across this on the website:?
?
"DopplerPSK does not provide any PSK31 demodulation; you should use a
separate program for that purpose. DopplerPSK does not provide any
compensation for downlink Doppler (which you would need for fully linear
transponders)."? ?
Question 2 - why not use something like HRD for everything (doppler, psk,
rotator, logging, etc) ?
(I believe I tried it sometime back by routing of the downlink audio back
into HRD)
?
73!

While it might certainly be possible to put together a solution that would
compensate your uplink so that its corresponding downlink through the
transponder holds stationary on a single spot on the downlink audio
spectrum, there are two reasons (at least) that I can think of to not go to
that trouble:
#1, the DopplerPSK app takes care of it perfectly already. The work has
been done.
#2, if memory serves, some radios do not respond to CAT frequency
adjustments when transmitting. In this mode, your uplink radio is
transmitting non-stop for the entire ~10 minute pass. If you have a
hardware/software setup that can only change RF frequency when in receive
mode, that will never happen during an NO-84 pass.
Lastly, like much satellite work, the uplink and downlink are two
completely separate discussions in this mode. While the 10m uplink works
extremely well with the DopplerPSK software and the HF radio of your
choice, receiving & demodulating the PSK31 downlink can be done by any
antenna/FM radio(or SDR), and computer combination of your liking. Just as
one example, my setup is:
TX: Windows PC > DopplerPSK > Signalink > FT-857d > MyAntennas EFHW-8010
RX: 70cm X-Quad > SDRPlay RSP1 > HDSDR on Windows PC (doppler track w/
Orbitron) > FLDigi

Scott to the rescue! This older version does start up and I'm waiting
for some telemetry to come in right now. And it does indeed connect to
Direwolf, which is much better than HS_soundmodem in the sense that it
doesn't use the soundcard to route audio from GQRX, but UDP instead.
Great! Thanks Scott.
@??????? all OCX files were registered, checked not once, not twice, but
thrice. So what I suspected already is that the recent versions of
AGW_onlinekiss_plus and getKiss share a similar code base, which is
different from the previous AGW_onlinekiss.
Now Jan, your instructions on how to install on Linux are very clear,
but if they can't be reproduced by an innocent passerby then they are of
little use. Have you tried it on a clean install, like Ubuntu 19.04?
Final request: can someone post or email me an example .kss file from
any current sat (like the XW, CAS, etc.) for me to test the decoder?
Cheers,
Hans

Glad to help.
I happened to already have the Astrocast DK3WN decoder on the linux
computer so I could verify that it worked properly with a .KSS file input
if you'd like to test with that.
The decoder and a .KSS file that I had previously collected can be found at:

Scott, Roy, Umesh, et al;
Part of the problem with PSK31 is that it required the adjustment for
changes in Doppler shift to be to be phase-continuous.? I think the Doppler
rate (delta-Doppler shift) at even 10m is too fast for most radios--what you
often get with CAT control, even if you can update while transmitting, is
PSK31 that jumps more than 31Hz per update, and that totally destroys the
phase continuity required to tell a '1' from '0'.? This was the "fun"
problem that spurred me to take a swing at it over a summer vacation.
When DopplerPSK applies "anti-doppler" on the transmitted signal, it does so
at the baseband audio level.? This works fine for 3Khz passbands on a 10m
uplink, but if you want to do it with SSB transponders and VHF and UHF
you'll need an SDR where you aren't limited by an IF filter.? ?The same
algorithm in DopplerPSK could be used on a complex signal in the SDR
architecture, and it could work equally on TX and RX in the processing
chain.? ?To the accuracy of the orbital elements everyone uses, if everyone
corrects their uplink and downlink properly there is no perceived frequency
drift by anyone using the satellite.? Just what you need for a GHz-range LEO
with a narrow-band transponder, eh??
Since the downlink of NO-84 is FM there is no Doppler shift in the baseband
audio of the downlink--you hear what the satellite hears.? If we get a
mode-K satellite it might be worthwhile to do a baseband demodulator in a
soundcard since the total change in Doppler shift will be small enough to
fit in a conventional HF radio's IF passband in both directions.
If the antiquated hosting site doesn't come back I'll get off my duff and
find a "proper" place for it.? It's nice to see people playing around with
it. (Thanks for bridging the gap in the meantime, Peter.)

Good to hear that you finally got it running. You can also have a look
at https://www.pe0sat.vgnet.nl/decoding/unix-tlm-decoding/ for some
overview.

Both AGW version will work with the config that I shared.

And yes I have installed it on multiple systems. Debian testing, uBuntu
16.04 TLS.
When you doubt the install, move the Ham specific directories to a
temporary location
and remove rm -rf ~/.wine and start again with the winetricks step and
the rest.

Question. All FM-only rigs of course only do 5 KHz steps anyway. Are we
finding that multi-mode rigs when placed in FM mode can actually step
smaller under CAT control?
If so, then we must point that out to users, since it will not work for
PSK31 even in FM.
Thanks for the reminder. If rigs do that, then I will add this to the PSAT
web page. The advice to not use auto-radio tuning except for 5 KHz steps on
the downlink. IE, not smaller steps.

Subject: Re: [amsat-bb] DopplerPSK
Scott, Roy, Umesh, et al;
Part of the problem with PSK31 is that it required the adjustment for
changes in Doppler shift to be to be phase-continuous. I think the Doppler
rate (delta-Doppler shift) at even 10m is too fast for most radios--what you
often get with CAT control, even if you can update while transmitting, is
PSK31 that jumps more than 31Hz per update, and that totally destroys the
phase continuity required to tell a '1' from '0'. This was the "fun"
problem that spurred me to take a swing at it over a summer vacation.
When DopplerPSK applies "anti-doppler" on the transmitted signal, it does so
at the baseband audio level. This works fine for 3Khz passbands on a 10m
uplink, but if you want to do it with SSB transponders and VHF and UHF
you'll need an SDR where you aren't limited by an IF filter. The same
algorithm in DopplerPSK could be used on a complex signal in the SDR
architecture, and it could work equally on TX and RX in the processing
chain. To the accuracy of the orbital elements everyone uses, if everyone
corrects their uplink and downlink properly there is no perceived frequency
drift by anyone using the satellite. Just what you need for a GHz-range LEO
with a narrow-band transponder, eh? Since the downlink of NO-84 is FM there
is no Doppler shift in the baseband audio of the downlink--you hear what the
satellite hears. If we get a mode-K satellite it might be worthwhile to do
a baseband demodulator in a soundcard since the total change in Doppler
shift will be small enough to fit in a conventional HF radio's IF passband
in both directions.
If the antiquated hosting site doesn't come back I'll get off my duff and
find a "proper" place for it. It's nice to see people playing around with
it. (Thanks for bridging the gap in the meantime, Peter.) Andy K0SM/2

While it might certainly be possible to put together a solution that would
compensate your uplink so that its corresponding downlink through the
transponder holds stationary on a single spot on the downlink audio
spectrum, there are two reasons (at least) that I can think of to not go to
that trouble:
#1, the DopplerPSK app takes care of it perfectly already. The work has
been done.
#2, if memory serves, some radios do not respond to CAT frequency
adjustments when transmitting. In this mode, your uplink radio is
transmitting non-stop for the entire ~10 minute pass. If you have a
hardware/software setup that can only change RF frequency when in receive
mode, that will never happen during an NO-84 pass.
Lastly, like much satellite work, the uplink and downlink are two
completely separate discussions in this mode. While the 10m uplink works
extremely well with the DopplerPSK software and the HF radio of your
choice, receiving & demodulating the PSK31 downlink can be done by any
antenna/FM radio(or SDR), and computer combination of your liking. Just as
one example, my setup is:
TX: Windows PC > DopplerPSK > Signalink > FT-857d > MyAntennas EFHW-8010
RX: 70cm X-Quad > SDRPlay RSP1 > HDSDR on Windows PC (doppler track w/
Orbitron) > FLDigi
