I, too, was curious, as I have the PL-660. Doing a search on it and on the SLV, I am guessing "SLV" stands for "silver." Mine's black. Howard Frank, _______________________________________________ RF

To clarify for others, I don't think you mean the detectors are battery operated. Rather, they (like mine in my hard-wired system) have batteries (typically 9V) used for backup power. Howard ________

I wonder, Mike, if you create horizontally polarized antennas (such as half-wave dipoles) that you can orient such that their nulls face the noise source.... They may have to be up high, though, to h

What am I missing here? Zip line is not coaxial; it is "balanced" line and requires a transmatch. With a simple transmatch you get the SWR down to 1:1 and you're all set. ? Howard N7SO ______________

You're asking the right questions, Paul. And balance is determined by the entire antenna system, not only the feedline and the transmitter (tuner). Most REAL antennas are unbalanced by their surroun

David, you can still get incandescent bulbs. While you cant get a bulb specifically at 100 watts, you can get them at a reduced wattage and, I think they are just as bright. I am looking at a box I
