Re: LPF 20 Meters

I've also characterized the LP filters (maybe 5 or 6) with my Siglent spectrum analyzer and had similar results. I think the best performance I had at a band edge was ~0.3 db down the worst was about 2 or 3 db down. Spreading the turns does help a little but I'm not going to bother with desoldering and taking turns off. 3 db down however is quite a bit of loss when you are dealing with QRP power.
