[amsat-bb] HO-68 Not Heard ?

Hi, I noticed the beacon info showed for 5 cycles before switch on ( 18h45 UTC) that temp was 21C . FM and DIGITAL was active normal for 13 mins 23 sec after switch on. There after beacon still on and reported xponder on but silent and temp was now 25 and 26C ? Wonder if this was a "tempreture" output shutdown ?
