Re: [LAU] Video micing question

On Monday 22 April 2013 19:57:06 Monty Montgomery did opine: When I found it, quite by accident as Susan mentioned it one day as I was lamenting the lack of such a cable, as flexible and well shielded as her type 7559 video cable was, a cable that I have used to replace the about 5 miles of the West Penn stuff that had been built in 3 months before I walked in the door in 84 to be the CE, and found I couldn't keep the color subcarrier out of the rest of the system due to the very poor shielding of the West Penn stuff, so the first runs replaced were the color subcarrier runs. Which I found once I had started to replace them, I had to replace the rest as quickly as I could in order to get things back in phase, the 7559 with its foam core was also about 8% faster than the West Penn, with correspondingly lower higher frequency losses. In the end I had to redo the DA's too, replacing straight ones with delay adjustable ones before I finally got it all back on the same phase. With the adjustable DA's, then I could treat the rest of the cable replacement in groups the individual DA fed. In the analog days, keeping every input to a 24 wide video switcher in color phase was damned near impossible, so I finally set myself an allowable error of 5 degrees, which corresponded to about 4.5 feet of 7559. Best for my sanity (what little I had the first 3 or 4 years while I was trying to make a tv station out of the crap I agreed to maintain) that way. Funny part about tracking the color was that I got half my off color reports from a color blind operator, who because he needed to, quickly got as adept at reading the vectorscope as I had been for 25 years already. He is still there, Director of IT Operations now. I'm probably boring the list by now, so I'll get me coat. :) Thanks for reading.
