|Hard to capture wonky SWR situation|
Well back to the topic at hand, I had my cables disconnected and the 3x5 card in place as we did have some severe weather roll through town the night before. I connected the cables, turned on the radio and started my PC. My plan was to get some FT8 contacts in the log before supper prep had to be done. As my rig was transmitting my LDG 200AT pro II turner started clicking which meant it was going through a tune session. This was odd as the tuner memory already selected the sweet spot and it was proven by the SWR meter on the Icom 7610. BUT......as I continued to transmit the SWR was going "wonky" and the LDG tuner was engaging to correct the issue.
There sure was an issue and I'm not feeling good about it. My troubleshooting began and here is what I did:
- I went to antenna 2 on the Icom 7610 which was connected to my dummy load. I transmitted into it at full power for about the time of an FT8 transmission. The result was no SWR issue so the 7610 seemed to be ok.
- I then connected the LDG tuner between the dummy load and my transmitter. I know there is no miss-match but if the LDG tuner was acting up it may do it in this ideal matched situation. The result was the tuner did nothing when I transmitted.
- I do have an LDG antenna switch (LDG DTS-4) in the maze as well. Once again I transmitted into the dummy load through the LDG tuner and then the LDG DTS-4 to the dummy load. Low and behold the tuner was trying to find a match again!
