Home brew stuff


Ive been busy lately building little projects.
most recent i built a band pass filter for vhf freqs.
i made 3 inductor coils and used 3 6-55pf variable caps to tune it down using the analyzer.

Re: Home brew stuff


built this 4:1 balun.
only after i used teflon tape did i start getting decent readings.
i plan to use this on a long wire and tested it by putting a 200ohm resistor across the poles and it gave good readings from 1.6-30 mhz.
