i recently acquired a yaesu 2800m. after a couple of transmitions the screen started blinking and the radio would not transmit or receive. everytime i keyed up the frequency would go away on the display. the radio would not scan when i tried to. i took it to the guy i got it from and he opened it up and told me that i had modded it. i told him that i hadnt. he took it home with him and tested it and talked to another ham and then told me that i had burned up the pll transistor. what is the pll transistor? i thought that there was a driver, a final transistor and then a pre amp or receive final. am i correct? i thought that the pll was something like a micro chip. long black thing that has several pins. can anyone tell me if its the pll or the finals? any input would be great.
