Hi Doug, all

this beacon looks good. COMPASS made no hard reset and all settings are valid.

Yesterday evening I heard the beacon and the temperature was 0° . So I commanded the satellite to switch off the heater at 0 degr. It seems that has worked. After this command I sent the treshold value to -50 degr.

Now we can see that the heater is still off (also at low temperatures). This evening I will try to change the voltage treshold - maybe I can switch COMPASS into powersafe mode. That means we can hear the beacon every 3 minutes.

Please stay tuned and listen to the beacon. Thank's a lot for all your efforts.

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!

73, Mike
