[TowerTalk] Rcs-4

[Mark]

I had terrible noise in the powered positions, and quiet with no power in pos 4.  My issue
was a animal chewing the coax jacket.  The resulting corrosion created the many little
diodes needed to make a broadband noise generator.  If the noise is more like birdies
rather than broadband, check the power supply and make sure there isn't some noise 
coming in that way, perhaps a bad diode or dried out cap.  Putting a meter or scope 
(Or an AC coupled spectrum analyzer if you have one) on the connection going to the 
antenna can quickly show a major problem.  

You may be able to use an ohmmeter to verify the dc integrity of the connectors and
coax. (I have had my share of PL-259s that did not have good soldering braid to shield.)
