Webb13 feb. 2016 · Replacing the radio with your test circuit would determine whether it's the radio or the power supply. One other option you might try is to simply connect a high value capacitor (20,000 MF or so) across your supplies output. This would probably help to eliminate the voltage drop when you turn the radio on. Webb18 maj 2024 · A powered receive loop that covers 500khz to 30mhz, and has the same characteristics as their magnetic loop antenna, but no tuning required. Not designed for transmitting, however if you have an HF radio capable of transmitting on antenna A and receiving on antenna B, then you can open up your ears and null out the noise. bohler insurance

WebbRemember that power-line noise occurs in bursts and at a rate of 120 bursts per second. Take a look at the suspect noise from your radio's audio output. (Note: The record output jack works best if available). Use the AM mode with wide filter settings and tune to a frequency without a station. Power-line noise bursts should repeat every 8.33 ms. WebbI worked for a power company for 28 years as an engineer and helped my company track down radio noise complaints. Now I'm retired and help hams here in Austin, Texas track down their power line noise. The big problem for both you and the power company (working together) is to find the exact pole the noise is coming from.
