Well, after what seems like way too long, I have this all working now. Test, test and test again, I missed afew solder connections here and there.

Is there a requirement to run coax cable from the loop amp to the decoder, or will any 2 strand wire work? I have alot of wire on hand but no coax. But I also understand the shielding may be playing into consideration here.

And, does the thickness of the loop wire matter? I plan on burying it under the track, inside PVC piping.
