Re: Discriminator tap question

Usually it is advisable to use a small value ceramic cap like 0.01 uf to 
block DC - no resistor needed - that would drop the signal some.

Doesn't hurt to use coax like RG-174 but not really needed. Depends on 
how much you want to put into a project labor wise. Also I always think 
about resale value - like putting holes for switches on a front panel.

If you have come here to find out about the Uniden BC-780 you have come to the right place! In fact the discussion of the BC-780 is the only acceptable topic on this list. Please. I hope this is clear to all group members.
