My main stranded twisted pair wire I had running between my studio equipment and the transmitter room decided to short out on me. This wire never worked well for me anyways being as I run most equipment using unbalanced audio. The AM transmitter got back into the wire too easily and had to use RF chokes all over the place. FM was fine but the wire still picked up stray EMF from lights and other devices.
So out of frustration and having a lack of money and time to get some new STP wire I decided to give a bundle of free RG6 CATV (satellite grade) coax a try. The stuff is a heck of a lot more fat than STP and a bit more heavy than RG59 at 75ohms impedance. The stuff I have is solid copper core dual shielded so I figured why not..
I attached some RCA connectors directly to the ends with my soldering iron. Gave them a test at around 35' length and they seem to work really well. No noise or RF interference so far from what I can tell.
Only problem I had was they are jelly filled cables so after stripping them my fingers were sticky and had to use alcohol to get the waterproof gel goo off.
Curious if anyone else tried using coaxial cable here as audio interconnects? Results?
So far these cables work better than STP unbalanced and all my previous brand name long RCA interconnects. I am sure balanced STP would rival this, but most of my studio equipment is consumer grade so naturally they have all RCA in/out jacks instead of the high end XLR three prong plugs.
I took both 35' cables an put electrical tape every foot to hold them together as one fat ass cable. May look fugly but these seem to work better than anything I tried so far. Almost glad my old wire shorted!

^What CM said about Radio Shack junk. That pretty much applies to most things they sell these days. I can hardly strip their coax without my coax stripping tool cutting through the extremely thin "shielding"
I may have to try my audio through some of the RG6 I have lying around. Since my TX and my audio are very close to one another it may help.
