Carrier tones every 15 kHz in 10m band

While tuning through the 28.3 to 28.5 MHz portion of the 10m band in USB mode, I get what sound like carrier tones very evenly spaced every 15 kHz starting at about 28.3 MHz. I am using an AOR AR8600MkII receiver with an AOR SA7000 antenna mounted on a mast outside. I am located in central NJ in the Princeton/Trenton area. What is the source of these tones? Thanks, Doug The horizontal sweep of television sets is 15750 Hz. Switch mode power supplies operate anywhere from 10 kHz to 100 kHz. It is not uncommon for either of them to ring and generate harmonics in HF. -- rb least you know the rx's working :-) |
