I just bought a brand new peaked and tuned 2970N2, hooked it up to my Ameritron AWM-30 twin needle meter fed into my Gainmaster. My vertical normally has a flat SWR. I have a room full of CB's, exports and a few HF rigs that I play on it from time to time. My CB's and exports are fed into my RM Italy HLA-150. Again, My meter is nice and flat with everything I use on that antenna. My station has an adequate ground. Never had any issues. My analyzer shows love for the Gainmaster. Well, I hooked up my new 2970N2 an my SWR shoots up to 2.0:1. I get garbled SSB audio. AM audio seems fine. The last Ranger that was on this antenna was an 2950DX. It had no issues. I must be getting some kind of RFI or something. When I feed the radio directly to the antenna and use the built in bridge, it shows the same SWR problem. Any ideas? wonder if the rig is spewing some harmonics? Strange, this is the only radio that has an issue attatched to the GM.
