Thanks to all who replied to my question!!! I removed about 9 or 10 tuns on the choke and moved the resonance up to about 19.1 mhz. I don't think that will bother either 17 or 15 mtrs. It's sure nice to have so many good minds to tell me what I have apparently forgotten so much of after all these years!!!! thanks again !! have a good day all!!!! carl / kz5ca
