SNIPPED I understand your thoughts on this, but if I had used KC in a current piece like this one, someone would surely say I should have used KHz. So either way someone would say I should have used the other form. Walt C'mon Walt, you can do better than this 'weak' response. You could define a new term. One that includes CPS for historical accuracy, and also includes Hz for contemporary usage. What about combining both into a new contraction, 'CZ' ? ;-) |

rust?Messed-Up Radials Can Generate Spurious Emissions

Cecil Moore wrote: hmm this kinda makes me wonder about my tvi as my antenna is near the building master tv antenna which is pretty rusty espically on the coax to antenna lugs never saw so much rust surpirzed i can see any station and it's missing a few elements that broke off i've been afraid to change it since a new antenna just might be worse then again it could be much better wish there was a way to test if the interference was strictly due to proximity/master amp or tv overload etc or 'sperious emissions' caused by the tv antennas rust i need a rust spurious emissions meter m |

Messed-Up Radials Can Generate Spurious Emissions
Hi Walt,
Enjoyed reading the story. Thanks! I live about 1/2 mile from a 50 kW broadcast station on 1360 kHz here in West Phoenix/Glendale and am within 5 miles of another half-dozen running 5 - 20 kW. Recently I became quite aware of a bad splice in the wires on my 80/40-meter dipole through the appearance of mixing products from the broadcasters all up and down both bands. Of course, I also saw the problem on transmit, having one value of SWR at 5 watts and an entirely different one at 500 watts. I hate to think of how many "mystery signals" I was generating in the process of getting that bit of test data! I keep telling people I am going to cut that bad splice out and patent it. How many mixer diodes do you know about that can handle half a kilowatt. 73, Jim, K7JEB |

Jonesy W3DHJ Then I should have said KHz/s, or KHzs, right? _That_ would be doubly redundant. :-) It would be the equivalent to saying "kilo-cycles per second per second".
