Thanks for the reply Don. Tried that and didn't work, still have the SWR issue. Tried the amp on a resonant frequency, and it still is showing a bad SWR, but not bad enough to always fault.

Make certain the connectors are tight. Replace with a different coax if you have one. You can always do a check on the KPA500 wattmeter by connecting a dummy load to the KPA500 (no tuner). 73, Don W3FPR On 6/2/2018 11:48 AM, jeff griffin wrote: > I recently brought my KPA/KAT500 north for the summer and hooked up to my > trapped multiband fan dipole that I use here in NJ.
