It's the combination of the PL and lots of people trying to use the bird.
We've seen this before, with AO-51, UO-14, SO-50, etc. When the newness
wears off it will work much better for everyone. I would like to see what
happens if they turn off the PL though....

That's an interesting obsevation Dan.
If we listen to the pass at 23.15 UTC, the pass is mid Atlantic with good
communications between Western Europe and the East Coast of the USA.
Italy / Eastern Europe is out of the footprint, so there should be fewer
stations on the XW1 uplink.
Thanks

Hello satfolks;
When i listen to the recording of the activity (12:35z) over Europe of
HO68 I
hear my calling is shortly interupted just that long of a packet. So I
think the
input of the transmitter is muted every time a carry is detected. If many
try to
send packets to the sat normal voice communication is impossible.
So my conclussion is: packet and voice mode at the same time is not a good
way.
Maybe that was the problem of the firsth FM-activity over Europe.
Many where trying to work the sat in packet and the input was most of the
time
muted. Only big gunns could get thru the packets.
Merry Christmas.

Hi Nick,
I bet you were hearing IO-26 at 1200 baud PSK. I was commanding telemetry
requests, so you might have heard a good bit of activity.

What sat is on 435.770 MHz transmitting 400 baud psk . I copied a sat with
Doppler at 19:20 Z today. I am located in Louisiana USA I and I don't know
what sat it is?
Merry Christmas

I recall Andrew mentioning that AO-51 had a software crash and he was in the
process of reloading it. Just wondering if it's back up yet?
And Merry Christmas to all!

this is far easier then the NASA PAO makes it out to be (no it doesnt happen
at 17,500 mph)
Ivan makes it look very easy...but it is more difficult then they make it
look and Ivan does it with grace. This time it is also quite pretty
Merry Christmas everyone

Many thanks to Amsat China for placing Xwang-1 in such a great orbit. On
the 23:20 Linear xponder pass tonight I had the pleasure of working Paul
2E1EUB and Danny ON5UE. Europe was in my footprint here in northern
Michigan EN75 for a good long time. Heard a good number of US-EU
contacts.on that pass.
Well done Alan and the China team.
Tnx and 73

That's what i suspected at my first try. As soon as a packet signal is
detected the TX shut off to restart with the ACK or command answer.
There is a weird capture effect involved if an analog signal overwhelmed the
digital one the digital retry sequences start until an ACK is
received.
I cannot find any sources to confirm how things behave could be a commanding
station can enlighten us?

I was able to copy the HO-68 Beacon from my QTH in FM19fa using my new Arrow
II Handheld Satellite Antenna. I wanted to thank the Chinese AMSAT Folks
for a wonderful gift to the amateur satellite community and wish everyone a
very merry Christmas tonight. I look forward to many QSO's on this
satellite in the coming weeks.

Luc, John and the Group,
I want to wish everyone a Healthy and Peaceful New Year, and I hope that
Santa was good to you; I know Santa gave me a terrific Satellite gift.
I asked Alan to give me a better understanding of how signals are processed
with XO-68, I hope his explanation below helps.
Dear Peter,
FM / Digital working principle is that whoever will relay signal to who
should transmit first. the transponder is not torn between the uplink
signals.
In other words, if the voice first, open the repeater and talk, this time
where the transmitting packet data is necessary to wait for voice
communication before end of the processing voice. By the same token, if you
are transmitting Packet data into voice link from time to time, the
satellite will continue to transmit the packet data to complete the data
frame, and then process voice request if the request is still active.
On the other hand, if there are a lot of very strong signals transmit to the
satellite at same time, the satellite receiver may be unable to decode 67Hz
PL correctly, so voice will be unable to be replied in that case.
Happy Holiday!
73
Alan, BA1DU

Hi Alan,
Well I can report like many others, the SSB operation is excellent and
clear comms.
My switch on was at 5 degs going North to LOS and I worked ZS6Y, ST2NH,
ZS1LS & ZS6BNE.
I was still copying at zero degs the stations in the North !
Congrats also for this fantastic SSB xponder.
