How are your tones? About 90% of the packets on the air are overdeviated,
distorted, skewed, unbalanced, not properly emphasized or demphaasized or
neither. These work "fine" terrestrially when weak signals are not involved
but may be 20 dB or more away from good performance with weak signals or
picky receivers. I can decode PSAT with 5 bars on the Kenwood TH-D72, but
have no other experience to compare. I remember good balanced tones did 3
bars on a D700, but typical bad terrestrial signals would not decode
sometimes with all 9 bars!
The ear can tell between good tones (listen to ISS) and bad tones (listen to
144.39!)
We have a bgighawatt experimental air defense radar near Wash DC on tethered
balloon blasting out power at 143 and 149 mHz and all over the place. I
wonder if PSAT gets overloaded by that? PSAT does not listen to carrier
detect, so when it has a packet to send, it sends it.

So, apparently, NO-84 is hearing me, but I've just never received any of
my own packets. My reception is hit and miss, even on high angle passes.
Guess I'll go ahead and get that preamp! (My radio and my ears are both
needing help hearing. This is gonna get expensive!)
Thanks for the info, Neil!

John,
A slight correction... 10am in Arizona is 1700 UTC. Arizona, except for the
portion of the Navajo Nation reservation in the northeastern part of the
state,
does not change its clocks for daylight time in the summer. It's UTC -7 hours
for local time, all the time. We really don't need the extra hour of daylight,
when it is so hot in the deserts during the summer.
Looking forward to this video presentation, and to hear the ISS as it passes
over. W7LB is the ground station for this contact, and Larry Brown is a
long-time AMSAT member and supporter. He has had a hand in other
scheduled ISS contacts in Arizona, and his experience should help make
this a success.
73!

Thanks for the many replies. I suspect that not using W3ADO-1 may be the
problem.
Listening to the monitor on my IC-9100 my packets sound just fine -- I can
hear no difference between the monitor and ISS downlink so far as quality
and level of the tones are concerned. I've also listened on another nearby
radio and the packets sound right to me. I'd like to be able to look at them
on a scope, but I don't have that capability.
Hearing NO-44 is not the issue. I hear it fine. It just ignores me.

Hi all,
Here is the scheduled time for this contact that I have posted several
times to the SAREX BB.
Pima County 4H/Vail Vaquero's 4H Club, Tucson, AZ, direct via W7LB
The ISS callsign is presently scheduled to be RS?ISS/OR4ISS
The scheduled astronaut is Mikhail Korniyenko RN3BF
Contact is a go for: Wed 2015-07-15 18:01:42 UTC 67 deg

Thank you Patrick, I did not know Arizona didn't follow DST. I often
have a hard time with these calculations and that is why I put "I
believe," to be corrected if I was wrong.
Also, the live feed starts 1 hour before the pass and that is why we
are talking about 10am local/ 1700 UTC instead of the pass time of
1801 UTC:

NO-44 PCSAT is usually only capable of about one good packet per pass. If
the batteries can get one long 1 second packet out, then it uses up the
batteries for the rest of the pass. (Very frustrating for control ops when
a user hits it while we are trying to command)...

Thanks for the many replies. I suspect that not using W3ADO-1 may be the
problem.
Listening to the monitor on my IC-9100 my packets sound just fine -- I can
hear no difference between the monitor and ISS downlink so far as quality
and level of the tones are concerned. I've also listened on another nearby
radio and the packets sound right to me. I'd like to be able to look at them
on a scope, but I don't have that capability.
Hearing NO-44 is not the issue. I hear it fine. It just ignores me.

How are your tones? About 90% of the packets on the air are overdeviated,
distorted, skewed, unbalanced, not properly emphasized or demphaasized or
neither. These work "fine" terrestrially when weak signals are not involved
but may be 20 dB or more away from good performance with weak signals or
picky receivers. I can decode PSAT with 5 bars on the Kenwood TH-D72, but
have no other experience to compare. I remember good balanced tones did 3
bars on a D700, but typical bad terrestrial signals would not decode
sometimes with all 9 bars!
The ear can tell between good tones (listen to ISS) and bad tones (listen to
144.39!)
We have a bgighawatt experimental air defense radar near Wash DC on tethered
balloon blasting out power at 143 and 149 mHz and all over the place. I
wonder if PSAT gets overloaded by that? PSAT does not listen to carrier
detect, so when it has a packet to send, it sends it.

My packet setup gets digipeated instantly on terrestrial APRS networks, and
works fine with ARISS, but even with overhead passes on NO-44 and NO-84,
when I copy the birds well, I can't manage to get an APRS packet digipeated.
Even if I crank the power up to 50 watts, using the M2 LEOpack antennas,
those birds simply are deaf to me. I'm sending to CQ via ARISS, as my
reading of the online docs seems to indicate that is appropriate. I've also
tried CQ via PCSAT-1 and CQ via PSAT (for NO-84) but still no joy. I've also
played with TX delay. Nothing works. What am I doing wrong? -- Mark D.

Content-Type: text/plain; charset=UTF-8
I put together an experimental program called DopplerPSK to compensate for
the Doppler shift on the NO-84 (or NO-83) PSK31 uplink.? In essence, its a
PSK31 transmitter that is merged with an orbital propagator to cause your
transmitted signal to drift exactly opposite to uplink Doppler effect.??It
does this in a phase-continuous correction so that you don't get errors due
to discontinuous frequency adjustments from controlling a radio in discrete
steps.
In the case of PSAT and BricSat, it should cause your signal to
stay?at?constant frequency in the?satellite's uplink?receiver, and thus you
should get a?stable frequency?on the FM downlink as well.? In turn, this
means you should be able to use your favorite PSK31 demodulating software to
copy the downlink since the frequency drift should stay well within the AFC
tolerance of the software.
Anyway, if there are any adventurous people who are set up to give this a
go, I would be interested in seeing if it actually works.
You can find a rough quick-start guide (which contains an explanation of how
it works and what you need to get started)?and the application package on
the rather minimalist page here:
http://www.frontiernet.net/~aflowers/dopplerpsk/dopplerpsk.html
It's an experiment, so be prepared for disappointment.? I am?:-)
