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 all,
This evening we had the same problem with HO-68. When at low elevation and
when the footprint was over Assia Minor and East Europe, entry to the
repeater was easy and I managed to make some contacts with UR4LRH, SQ9MES
and SP7TEC. When the footprint covered part of Italy I made a last contact
with IW6OVD and from then, when many other stations from Western Europe
where trying to use the bird, only fragmets of calling CQs were heard during
the whole pass.
Dan ON5UE thinks that the problem is due to the use of packet and voice mode
at the same time, since many are trying to work the sat in packet and the
input ismost of the time muted. Anyway, I think that the receiver cant
demodulate any of so many signals competing for demodulation. When the sat
is over South-East Europe with limited activity QSOs are easy and with
strong signals. Over West Europe with so many stations competing for entry,
the receiver is muted.
Merry Chrismas to all

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
David

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

Hi Alan,
We just experienced our 1st live pass in South Africa.
Easy QSO's with ZS6Y and ZS6BNE.

Congrats to the Team for a wonderful new Sat to have fun with.
Seasons Greetings and Happy Holidays to All the Satellite fraternity !

An audio recording of the HO-68 pass over the far western
USA 24Dec2009 1807z is on my webserver:
http://www.papays.com/HO-68_24Dec2009_180656z.mp3
The same scenario continues with packet competing with the voice
repeater. How the two work together is not obvious but it does
seem that the packet shuts down the voice repeater for a period of
time. What makes the voice repeater start up again is not clear.
I decoded some packets on this pass. I have the TNC set to
Date/Time stamp the packets so we know exactly when they were
received. The clock is accurate to within a few seconds.

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.
