Ok I have a FLL transmitter circuit, the VCO works well on its own, however when I place the prescaler for the pic micro near the circuit the digital roar from the 74ac logic screws everything up due to harmonics etc.
I was wondering how big a cutout I could have in my screening can made from single sided PCB I could have.
I was planning on putting all the digital stuff in its own totally screened enclosure, just a cutout for the 2 line display, about 20 by 75mm, just wondered whether this would be an issue at 100MHZ.
