Re: 2.5 MHz low pass fiilter uses no toroids, SMDs #ubitx


Good looking trace from a HPF made of surface mount inductors and capacitors. I'm not surprised by the use of s.m. caps but inductors does surprise a little.  I would have hand wound them on T37-2 (at a minimum).  Are they anything special Glelnn?  --Paul VK3HN.
