Thanks for that link, exactly what I was looking for.


Thanks also for your work on the filter, I haven't seen an LC filter with such steep characteristics and low loss before.? The 20m and 15m extrapolations I entered into Elsie model great, I'll?

build a couple and see how they stand up to the spec analyser.
