Hi, I have a question ( or two ) on the Quadra amp from Yaesu; 1) I leave the power supply turned on all the time ( is that OK ??) in a rather cold room and I still hear the fan turn on every 30-45 minutes for 3-5seconds is this normal ?? 2) I thought that the Quadra was supposed to turn on when the FT1000MP was turned on, is it supposed to ?? Thanks Brian
