XB-200 filter design for 70MHz and 432MHz

Post by kartsan » Fri Apr 10, 2020 12:24 pm

Hello, a question about XB-200 filter: I'm about to use my external filter for HF ham frequencies but it also contains 50MHz band which is already on XB-200. I'm interested in 70MHz and 432MHz bands. I'm having idea of replacing 50MHz and 220MHz filter components on XB-200 to 70MHz and 432MHz. 220MHz band is useless here (Finland) anyway. 70cm band is more interesting.

Before starting any filter calculations, I decided to ask here has anyone already done this or is it a feasible idea anyway?
