Re: Tuned input


 

The RF flows into the center common pins in and out.? The coils are across the common pins when keyed.? These relays are labeled DPDT but the common pins are tied together!!!!!!!!!!!!!!!!!!!!!? ??

I checked the NO and NC operation and it passed. I did not think to check ACROSS the two center poles to each other!

I got the new relays from mouser. I have 10, 15, 20 and 40 working now!? ?The cut off is very sharp. On 40, at 8MHZ its brick wall steep cut off.? Flat in the band.

I am going to work on 80 and 160 today.
