I've been watching sense day one of the thread. This would indeed be a handy little devise if one has any doubt as to weather any of there channels is having an issue in regards to signal strength. I was all set to build Adrian's original version with GRJ's first OSH zip file but thought I'd wait in hopes the other electrical gizmo gurus would jump in a crank this thing up a couple of notches. Low and behold, BAM!
A kit would be nice. However, a zip file and a parts list would work for me thank you very much.
