Good Morning.? My name is David? G4RVH.

I've been a radioham for over 40 years so have built my complete working radioham shack and all of the equipment homebrew ie transceivers and test gear.

A labour of love.

Plus I built the G3XJP? PicAtune Auto ATU years ago as I know Peter Rhodes quite well.

Anyhow maybe I am missing something but would have thought it to be important to have Back EMF diodes across each of the relays as a safety factor to protect the 2N7000 FET Transistors.

I also just for my own benefit are going to fit tiny LED's across each of the relays so that I definitely know that all the relays are switching via the transistors,? just a peace of mind quick check.
