That¡¯s the sound I heard when I first powered up my beautiful BITX40. I immediately cut the power, traced all my connections, everything looked great. Cautiously I applied power and turned on the radio, it tuned in perfectly. After some playing around I tried to transmit¡ nothing. No power out. Well I guess it was the transmit circuits that made the pop sound when I powered it up.
I believe the source of the snap pop (a minor flash too) was close to the PA-PWR input, close to the larger black torrid and the heat-sinked transistor. There is no visual damage on the components or board. Any ideas on how to trouble shoot?
Oh, just a note, the power supply was a powerwerx switching power supply, so nice and clean. Any help would be great!
Thanks!
