Author Topic: Problems with FT-100d/ATAS 100 @ 10 & 12 meter  (Read 453 times)

Problem that I am having is that the antenna tunes, (manually and via radio), but when I push the PTT on the microphone mode=AM/SSB, the high SWR light comes on. If I try to transmit on FM instead of AM/SSB 75% of the time it works as expected.  

I have tried the obvious things like re-positioning the antenna, adding more coax (how much is TO much???) and adding some addtionional grounding to the antenna.

Any help would be appreciated.

Hi Jim,

This sounds like the common internal grounding problem experienced with the FT100D and not a problem with the antenna.  Check the product reviews here on eham for the FT100D, I think you'll find your answer.

I had the same exact problem with my FT-100 and the ATAS antenna. I grounded EVERYTHING, and still couldn't get it to tune on 10 or 12. The problem? Not enough coax! When I re-mounted the radio from under the dash and installed the separation kit, I grabbed a 20-foot run of RG-8X I had on the workbench. I noticed it tuned to almost flat on 10 and 12 and went with that length of coax to finish up the installation. No problems since then. I orginally had about 6 feet of RG8X in the first installation.
