Hi Jim, Thanks for the New Choke Cookbook. Looking at your data, it seems to me that I could build a two core choke for the higher frequency bands and "spread" the overall choking impedance out by using different turns on each core, ie 11 turns on a 2.4" and 12 turns on a 2.4" . I believe

Hello Andrew, My set up is similar to Johhny, but with the cables connected from the KPA100. I am using relatively resonant antennas, so have tuned the KPA100/KAT100 combination into a dummy load on these bands and set the KAT100 in the locked mode (sorry can't remember the correct designation)
