My KXAT3 internal antenna tuner clicks and finds a match for my KX3. It has been an intelligent and flawless work horse for using my doublet on all HF bands, 450-ohm line, 4:1 balun, and short coax, good reports, fine DX. However, it now appears to be failing to remember settings. It began by needing resetting upon band changes. Then it began needing resetting within band. Then needing resetting upon even small changes in VFO frequency. Now it has taken to not holding a setting at all. Upon transmitting, antenna SWR will go high. Tapping ATU TUNE again will begin a new matching process. And, again, SWR goes high upon transmitting. Have any of you experienced this? Have any of you a known remedy? I have begun tests with an imperfect dummy load (a 15-watt light bulb). The KXAT3 will bring the light bulb's SWR of 3.3:1 down to 1.5:1. When transmitting, SWR reverts to 3.3:1.
