1. Topband: Remote relay via single wire (score: 1): Author: W2pm@aol.com; Date: Wed, 16 Nov 2005 17:50:23 EST; Can anyone comment on the advisability of powering-up a remote DC (24v) relay - about 200 ft away with a single wire with the other side simply the ground? It would be a dedicated supply not connecte; /archives//html/Topband/2005-11/msg00181.html (6,298 bytes)
