I would like to install two 2.8kc Inrad filters, and one 6kc Inrad filter. What is the best way to accomplish this. I have looked at the info at k1deu's website, ( http://www.hamelectronics.com/k1deu/pages/ham/projects/ft-1k/ft-1k_index .html ), but I think this relates to the MP only, and not the mk5. Any input will be greatly appreciated. 73 Ken=20 w3kmp NRA Life Member CRA 1401 ECARS 3779=20
