Very true....I seem to recall as a young man thr ARRL had a small book on this topic that might be handy.Suppressing the noise sources, before they can "transmit" on your channel is the only practical solution, most of the time.
The noise blanker in a radio is usually built to suppress spark-plug noise. The pulses are brief, and have a comparatively long "silent" interval between them.
Buzzes, whines, and "hash" noises will simply cover up the distant station you want to here. Noise blankers don't help with those kinds of noise.
Filtering that stuff at the source, before it can escape into the air just works better.

If the suggestions that have been offered don't work you might consider looking into a DSP speaker, or one of those digital noise suppressors. They're made by West Mountain and a few other companies. In some cases they work extremely well. You might also want to look into a Autek qa-1. It's an older analog filter. In some cases it actually works very well a removing or dropping that noise down to an acceptable level. All the items I mentioned can be used with a CB radio. Good luck. 73I'm sticking a CB on my boat, where there is lots of noise generated by the battery charger, the generator and other sources. What stock CB radio has the best noise suppression of them all?
Thanks.

Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
