[Kenwood] Good rigs for power line noise

2003年3月24日 10:10:52 -0600

Hi Guys,
One of the best rigs around that you will not hear noise on is a Collins,
of course you won't hear many signals either unless they are 40 over S 9.
Been there, done that, but no more......

With a noise level of S6 I would put my time and energy into finding the
source rather than trying to "filter" it out
First swing the beam and on 15 or 20 and get a general idea of the
direction where it is coming from. Next beg borrow or purchase a portable
receiver for 450MHz which has AM (NOT FM) receiving capability and a small
beam (I use a Standard C510A). Knowing the general direction the noise is
in, start walking in that direction pointing the beam at every house and
power pole along the way, at S6 the source is less than 1/4 mile away
probably less than 1000 ft. Most power companies will be more responsive if
you can point to a specific pole with a problem, and for all we know right
now it may be the thermostat on the hot water heater or your doorbell
transformer.
Good luck
Dave
