Ken,
I had a listen yesterday but heard nothing, will listen this afternoon. Just
had a magnificent pass on FO-29 with seven stations contacted. The whole
station worked like a charm, next pass in an hour or so covers quite a bit
of the east coast USA.
Using: RX: Airspy Mini, TX: TS-2000, Innov Yagis for 2m / 70cms, AlfaSPID,
Own software
No fading on the satellite at all, was a stonking signal from AOS to LOS.
See you Sunday...

Subject: [amsat-bb] Alsat-1N ( Pratham ) satellite Beacon heard
Hi all,
Pleased to report that I heard the beacon ( 145.980 mhz ) on Alsat -1n -
Pratham on this mornings pass
here in Wales - UK The pass was at 0945 GMT and being at a reasonable
height easy to monitor.
I used the keps that were originally posted and my equipment my usual
Kenwood TS 2000 and tracking with the "ELK " antenna.
If I get a chance I will listen again on the next pass and perhaps get a
recording - I wonder how the data downlink was performing if switched on
whilst over France.?
Congratulations to the team and also of course to "ISRO" for the success on
the launch.

What is required to operate from the ship and while in Cozumel?
Do we need authorization from the ships Captain?
Do we need IARP? Even if Extra Class?
I thought all these questions were going to be answered and posted to the
AMSAT website.

Carnival allows amateur radio operations on board per their policy. An IARP
is required for any US licensed ham as the ship is registered in Panama.
This was detailed in this week's ANS.

Hi again,
I listened for Alsat-1N ( Pratham ) on the subsequent pass -same frequency
and equipment but also with an update to the keps. Those issued on the BBS
posting.
I regret to inform you that I heard nothing ? The pass was lower and in
a sector were I have difficulty
due to screening and reflection problems - Weather had also changed with
very low cloud,mist and rain.
Even AO-73 would not decode the dashboard data in the same sector during
the same period.
I am certain about hearing a CW beacon in the previous pass.
I had been setting up my gear for an AO-73 in that earlier pass and had USB
selected for the downlink data.
Noticed that Alsat-1N was also approaching in the same ball part of time
so decided to have a listen on the
145.980 Mhz frequency. That was when I started to hear the CW beacon
but still had USB selected I selected CW and got a better copy as it
approached.
I wish that I been set up to record but of course was not planning for that
particular satellite and pass.
Had I done so it would have been useful to clarify any doubt about things
and I am unsure why the subsequent pass showed no activity.
Hopefully the satellite is alive and active and someone else also monitored
and maybe even recorded the pass.

Hello Ken & everyone.
Hoping to confirm Ken's possible Pratham CW beacon reception, I was
tracking Pratham on a max 56? pass down the USA East Coast at 14:46 UTC
today.
No signal was seen where it "should" have been, but a strong and clear CW
beacon appeared below the expected frequency.
Replay of the recording with appropriate demod revealed that the CW in
question translated to "M O V E 1".
A Google search lead me to object 39439, cubesat "First Move" which
transmits the MOVE1 CW beacon on 145.970.
Adding that satellite to Orbitron and walking back to the time of my pass,
the First Move satellite was indeed in the area (trailing the expected
track of Pratham).
Running the simulation back to Ken's reception report at 09:45 UTC, First
Move was also in his area. And, according to the footprint in Orbitron,
First Move would have just been in range of the UK - in fact very close if
the time was closer to 09:50 UTC.
I don't know if this is the CW that Ken might have heard, but in any event
I unfortunately did not see any transmissions around 145.980 on this
morning's pass here that might correlate to Pratham.

Correct me if I am mistaken;
Pratham and AlSat-1N are two different satellites. Pratham is turned on
only over India and Europe, and AlSat-1N has a 90 second telemetry
beacon 437.650 9K6 FSK. (actually running 4KHz low 437.646)
I have only been able to copy garbled data from AlSat-1n the last three
days.

Hi Bob,
Use the UZ7HO hs_soundmoden and un-tick non-ax25 filter.
Similar to STRaND-1 ALSAT-1N it is not full AX25
Regarding PRATHAM, it should do CW on 145.98 during the whole orbit and
AFSK 1200 on 437.455 over there command stations.
But so far nothing heard

Bob,
FWIW Pratham is identified in
http://celestrak.com/NORAD/elements/tle-new.txt as 2016-059C. I've set a
timer to remind me to listen for it this evening, two good passes where I'll
hear the CW beacon if it is on.

Hello Ken & everyone.
Hoping to confirm Ken's possible Pratham CW beacon reception, I was
tracking Pratham on a max 56? pass down the USA East Coast at 14:46 UTC
today.
No signal was seen where it "should" have been, but a strong and clear CW
beacon appeared below the expected frequency.
Replay of the recording with appropriate demod revealed that the CW in
question translated to "M O V E 1".
A Google search lead me to object 39439, cubesat "First Move" which
transmits the MOVE1 CW beacon on 145.970.
Adding that satellite to Orbitron and walking back to the time of my pass,
the First Move satellite was indeed in the area (trailing the expected
track of Pratham).
Running the simulation back to Ken's reception report at 09:45 UTC, First
Move was also in his area.? And, according to the footprint in Orbitron,
First Move would have just been in range of the UK - in fact very close if
the time was closer to 09:50 UTC.
I don't know if this is the CW that Ken might have heard, but in any event
I unfortunately did not see any transmissions around 145.980 on this
morning's pass here that might correlate to Pratham.

Jan,
I had UZ7HO_HS installed on my computer, but have not used it much.
On the 18:00 utc pass I tried it out. I certainly copied more than
MixW, but did not display any of the telemetry data. What I received
were frames like these:
1: <NON-AX25 frame Len=20> [11:07:27R]
1: <NON-AX25 frame Len=19> [11:07:27R]
1: <NON-AX25 frame Len=32> [11:07:27R]
1: <NON-AX25 frame Len=20> [11:07:27R]
I have to work on settings...
Thanks for the help.

Hi Bob,
Use the UZ7HO hs_soundmoden and un-tick non-ax25 filter.
Similar to STRaND-1 ALSAT-1N it is not full AX25
Regarding PRATHAM, it should do CW on 145.98 during the whole orbit and
AFSK 1200 on 437.455 over there command stations.
But so far nothing heard

Just had a directly overhead pass of Pratham here at CM98, 1755 UTC.
Heard the CW beacon, but rather weak given the overhead pass, and very
chirpy. Strongest signal was just after TCA, but there was surprisingly
very little QSB overall. Is it stabilized already?
I couldn't copy the data by ear (too fast), and FLDIGI couldn't make
much sense of the signal either, probably due to the chirps and being
just above the noise. AOS, TCA, and LOS matched predictions pretty well
for object 2016-059C.
Equipment here is a Yaesu FT-847 (CW mode), with a 2x8 element beam and
Khune preamp at the rotor. I tried both polarizations, and it didn't
seem to matter much. Presume the spacecraft's antennas are linear.
