Clear Packets this morning on distant pass by London

The distant pass by London 540 Miles 11 degrees above Horizon was clear between 8:48 to 8:52 on the morning of December 30th 2015. The first minute from 8:47 and last minute from 8:53 the data signal lost in the squelch noise.

The data was very clear.

The remaining times today over London are 10:22 to 10:28, 11:59 to 12:05 almost directly over London, 13:25 to 13:41 and 15:13 to 15:18 peaking between these times.

There was clear data signal on 145.825 but not on 145.800.

The distance from London during the clear pass were 720 Miles above North Spain across South France and Switzerland/Italian Alps into Austria 720 miles from London. The signal clear the distance of 880 Miles along the trajectory.

Shortest distance was 540 miles.

ISS Digipeater

Can someone please confirm the ISS Digipeater RS0ISS on 145.825Mhz is now back in service, and is the RS0ISS-11 Packet Mailbox still operational. Lastly is the 437.550Mhz digipeater working. 73 Brian. ZS5SB.

Re: ISS digipeater and BBS -=ZS5SB=-

Hello Brian,

Take a look at:
Scroll down to ---> Recent activity.
At the moment I write this message I can see the last ISS packet traffic is from a long time agoo.
AMSAT Live OSCAR Satellite Status Page website shows also info:
ISS crew power off the ISS amateur radio station for safety reasons because of Vehicle or EVA activities.
The ISS packet station is only active on 145.825Mhz simplex.
The ISS UHF radio is not active anymore.
RS0ISS-11 bbs was in the past used from the ISS Kenwood TM-D700.
This radio is not active with packet anymore.
Last period the ISS Erricson + packet modem where active with the RS0ISS-1 bbs callsign!
Somethimes amateur radio operators posting that the ISS packet system is ACTIVE while it is off.
Probably they hear packet from a packet satellite or from a local station.
It would be much better if people post an ACTIVE report when they really see the ISS RS0ISS packet callsign on their
own screen while the ISS is in their range!

ISS Digipeater

Hi Cor, Thank you very much, you have answered all my questions. I was also suspicious that some HAMS report "ACTIVE" in error. I think its best to copy and paste the ISS packet ref on the report as some do. Best wishes & good DX for 2016, Totsiens Brian.

Re: ISS digipeater all questions answered -=ZS5SB=-

Hello Brian,

Can you tell us what transceiver, antenna and software you use for packet radio with ISS?
Have soon a happy new year 2016!

Re: ARISS will be off air for a week

Unplanned EVA will result in extended time off for ISS amateur radios. Unscheduled-spacewalk-possible-on-Monday 21/Tuesday 22 Dec.

The International Space Station’s mission managers are preparing for a likely unplanned spacewalk by Astronauts Scott Kelly and Tim Kopra no earlier than Monday, Dec. 21.
Kelly will be designated Extravehicular Activity crew member 1 (EV1) wearing the suit bearing the red stripes, and Kopra will be Extravehicular Activity crew member 2 (EV2) wearing the suit with no stripes.

Late Wednesday, the Mobile Transporter rail car on the station’s truss was being moved by robotic flight controllers at Mission Control, Houston, to a different worksite near the center of the truss for payload operations when it stopped moving.

Hopefully the planned SSTV targeted for Dec 26-27 will still go ahead fingers crossed.!!

RE: ISS Digi is back

Great to hear that! I tweeted @RF2Space (the group of people at NASA who manage the amateur radio equipment) last night and got a reply from them saying that they will check. Seems like they sorted it out and everything is back to normal again.

Seems to have done the trick.!! Hopefully will soon get some confirmed dates/times for HamTV for early Jan 2016.
