Happy New Year! I bought 26 ac of land with an old house for a remote station. The power company buried the last 300 ft of power line. Now, the location has 100ft tower with 40-10 beam, 4 sq on 80, w

While I don't know the hardware Jim is suggesting, a spectrum analyzer that can provide both amplitude and waterfall is EXTREMELY useful in diagnosing RF noise. See my website and also NK7Z's. On my

Do you know if the "main power line" is 7200V or 14400V? The older lines are 7200 and more prone to transformer issues. At my site, when they upgraded the lines to 14400 the line noise got much bette
Thank you for many useful directions. As my noise is usually cancelled completely by a noise blanker, this suggests a powerline noise. The noise persists with the local power off so it is not generat
I'd suggest that you, or your neighbors may have a solar power system, inverter, batteries that might be the culprit. Solar power is ubiquitous now and not all of the associated equipment operates cl
I don't think so, unless you are using some sort of noise cancellation with two antennas etc. Noise blankers can be very effective against impulse noise, typical of line noise. However, they don't wo
I had two intermittent noise sources that the NB was marginally effective on. One was the dishwasher, the other a flat screen TV. Not plasma, but an older LCD fluorescent backlit model. Al AB2ZY I do

Remember that if you have any UPS units they will continue to run when your main power breaker to your home is turned off. Sometimes this is overlooked when searching for RFI. GL, 73, Ron W8RJL Sent
Noise from electronic devices can have that impulse nature, for which noise blankers are effective. The AM audio often has harmonics of 60 and/or 120 Hz, as does that of power line noise. Most often,
Did the lineman say what he found bad? Cracked insulator? Bad lightning arrestor? Bad ground? Something else or a combo of several? Just curious. N3AE _______________________________________________
A manager said they disconnected the transformer. That pole was old and not used in years so there was no reason to keep it on. Ignacy NO9E _______________________________________________ ___________
