修正しました. ↑
回路というほどのものではありませんが、COMPASS-1 を復旧するための
DTMF信号送信ケーブルを作成しました。本日(8/17)夜のパスで実験して
みます。(常時送信状態でよいのかな？) Tnx> JA0CAW
****14#200# heater off to -55 degr
THIS IS THE VERY IMPORTANT COMMAND
****13#200# heater on to -55 degr
****16#170# critical batt threshold to 3.3V
****15#255# low batt threshold to max -> charge batteries
The commands consist of 4 stars, two numbers, a hash, 3 numbers, and a hash.
This commando should switch the internal heater off. I think that's the only
way to save power. If COMPASS receive this sequence successfully you can
hear a short confirmation beep.
