80m Filter

I’ve been working on a direct conversion receiver, on and off (mainly off with a couple of spurts) for a few months now based on a talk by ‘Nick the Vic’ M0NTV, and I recently put together the 80m filter. It’s designed to be modular which is quite nice because it does mean that I can dip in and out. I’m going to put together a writeup of what I’ve done, but for now a couple of pictures.

You can see in the first picture that I’m using a ‘mint tin solder pads’ PCB which I purchased from Kanga UK, very convenient for using with my mint tin, I’ve found it great and on the reverse side it has the same but with split pads.

Not pretty, I’m going to try to get some bulkhead SMA sockets for next time.
