I just tested one..
So will be looking to built a prototype tonight.
They have 240V AC 10A contacts so should be fine for a qrp 4SQ, even up to 150W I believe.
Other than a trip which might get the odd mention I will detail projects I am working on, what I want to be working on and what I have otherwise to report on. I will update the individual projects as they advance. As asked I have started to catalogue the references I have follow the link on the left where you can obtain them too. Want to email me wander over to qrz.com and you'll find my email address there. Also twitter @m1kta_qrp
