Hi all,
I got a lot beacons and we can see that COMPASS survives all the eclipses. The battery voltage is increased to 3.67 volts.
Please keep on trying to listen the beacon and send the following commands:
****13#200# threshold heater off to -55 degr
****14#200# threshold heater on to -55 degr
****15#255# low batt threshold to max -> charge batteries
****16#255# critical batt threshold to max -> emergency mode (to
save power)
If COMPASS receive this sequence successfully you can hear a short confirmation beep.
Uplink: 145.980 MHz FM
Downlink: 437.275 MHz
Thanks for your time and your efforts!

Hi Mike,
Well, this is interesting... Good news, I guess, but also a puzzle.
I just had a low pass, off to the west, 10 degrees at the maximum. I tried sending the commands below, as I have tried before. As before, there were no confirmation beeps. But, right in the middle of the pass, the beacon came on. Nice and strong, as if nothing were wrong. Unfortunately, I wasn't able to record it, so I don't know what it said. I let the beacon finish, and sent the commands again. Again, no beeps.
I thought that I have been doing this right, but not getting a confirmation beep tells me that my commands aren't getting through. I'm sending the commands by hand - DTMF pad on my Yaesu 736r. I've set up another receiver to verify the tones are being sent, and they sound ok. Any ideas? For example, is there a specific rate that the tones need to be sent?

Hi Mike,
Home again and back in business re Compass.
Sent your new revised commands at 2131 UT and all acknowledged OK. Compass had just started a beacon at AOS and I received another one 10 min later. Both identical data except for battery temperature as shown below.

This looks very good. It is the first telemetry that has the heater off, which should help the battery charge to full capacity. - Duffey On Sep 7, 2008, at 4:07 PM, Alan Cresswell wrote:

I do hope that I just pressed a wrong button but I was listening to the downlink on AO-51 during the 23:31/41 utc pass and halfway through the pass (I copied P9HA, YY6IEA and W6NVE) I lost the downlink compeletly and I just had the normal static - was this my error or has the software taken a dump again?

It was just the scheduled mode change. See http://www.amsat.org/amsat-new/echo/CTNews.php .

It was the scheduled mode change. There were a number of commands that needed to be done for this change, so I took the pass with the higher elevation at my QTH in east TN.
AO-51 is now in L/S and V/U 145.88/435.150 dual repeater mode.

Please keep on trying to listen the beacon and send the following commands:
on the trans-Atlantic ascending pass at around 23:55UTC on Sept. 7, I seem to have succesfully commanded COMPASS. At least it gave a beep after the second command. Moreover, I heard (very chirpy!) telemetry from it. Once I hunted for the signal with RIT, I lost a bit of it, but the last elements seem to be 201800b72903 unfortunately, the beacon decoder will not take a partial beacon, so someone else will need to decode this.
It was a great thrill to be part of the effort to sustain this project. Thanks to all involved for requesting our assistance and entrusting us with this task

At the ascending pass around 01:40UTC Sept 8th, I received confirmation on all four commands. Moreover, I once again got beacon telemetry. 29000000000000201800bb2902, which reads as battery at 3.67V, heatermode: off and power level: emergency.

COMPASS-1 beacon heard (while eclipsed).

Hi Mike,
Had a Compass pass here about six or seven minutes into eclipse. Sent commands and first 2 were acknowledged but it was low on the horizon by this time so maybe it was too low for any further commands to be received. Received a beacon as follows. Solar panel currents seem a bit strange given that it was in eclipse!
