Fired up my K3 the last couple of mornings and noticed this. As the autotuner was searching for a solution the power output was slowing rising. Not so unusual right . But, after the tuner made a match the K3 was reading about 40w of output. I went into tune mode again (key down), the antenna was matched 1:1 but the output was slowly coming up so I let it continue. A slow climb to full output after about a minute or so was achieved. I have eliminated the tuner as the problem by using it on another transceiver. I'm thinking it may be a heat related issue somewhere, my guess is it's possibly on the PA board and possibly a solder problem, but then again it could be that same issue anywhere in the drive chain. If I don't transmit for a period of time it will repeat but not as bad as from a cold start. No other abnormal behavior has been noted. Any ideas ? Thanks in advance. Serial # 3378
