I am looking for a PL filter or audio amplifier with PL filter I can use
to process discriminator audio from a VHF Mitrek. I've looked at these:
http://www.repeater-builder.com/rbtip/plf.html
http://www.repeater-builder.com/rbtip/muteboard.html
Both include a 160Hz filter that uses a 0.15uF and a 6H choke. But where
in the world do you find a (small) 6H chocke if you don't have any old
Motorola parts to salvage from?
Any alternate proven designs for a PL filter?
Thanks,
Adi
