Me too, i have this problem especially before when the sky went dark while i was far from my transmitter (i.e. more than 100 meters away from my AM25). My power supply is a NexxTech 12 VDC 500 mA.
PS: btw, Bill, i’m impressed that you broadcast at the beginning of AM band. How much coverage you broadcast? I guess you have a big loading coil for 650 kHz. Have you ever experienced to broadcast at the end of AM band (> 1500 kHz)?
