Ultimate Labs construction (Part 2)

I have added multi band options to the U3S recently. Part 2 of the project deals with the addition of the switched LPF relay board and additional LPF.

You can read the story of the construction, thankfully without the addition of any smoke.

You can read Part 2 here.

If you missed Part 1 and you want to catch up with the start of the project I have linked that for your delight..32555731465_161f49183f_k

Dave enjoys all aspects of the hobby from contesting in a wet cold field (OK enjoys is a bit strong) to building beams and working big DX. Portable VHF and HF can provide lots of opportunity to try new things, test out antenna and enjoy a field day based curry.
