I am getting erroneous SWR on ANT on my 6600m these are as high as >3 and the antenna tuner not being able to tune a 50ohm verified dummy load. I have conducted testing, and the only remedy is a hard reset of the radio(long press power on with white power light), which then lasts for hours to days. First let me say that I have verified the antennas and loads used in testing are good using an antenna analyzer and in direct comparison to SWR readings on ANT1 which is accurate. Has anyone experienced anything like this before? FYI test criteria: firmware 18.104.22.168 and 22.214.171.124.
