Carrier on 7033 kHz
« on: April 10, 2022, 1605 UTC »
There has been a steady carrier on 7033.04 kHz for several weeks. A lot of radio amateurs have been trying to track it down. I have been informed the source has been found by someone, but is not known to the general ham population yet. It's an odd signal. It is not strong enough anywhere on a Kiwi SDR receiver to indicate it is running high power. Yet at night in central Illinois I have seen it on SDR stations in western Europe. At sunrise in Illinois I have seen it on SDR receivers in Hawaii and Australia. During the daytime in USA it is only detectable on SDR receivers in western USA. It is the strongest at Colorado and Utah stations. Beam headings indicate it is somewhere in Colorado, Nebraska or South Dakota. When I find out what its location is, I'll let you know. I am really curious!

It's been over a month now, and the 7033 carrier is still there.  Tonight at 0730z I can only hear two signals in the 40 meter CW band here in central California:  the "K" Russian beacon on 7039.2 and the mystery 7033 carrier, which is currently S4.

There's a 25 page discussion about it on the QRZ forum.  Utah or Colorado continues to be the suspected origin.

The 7033 carrier went off two days ago.  According to the above thread on the QRZ forum, the FCC tracked it to a summer cabin owned by a ham in Alma, Colorado.  The carrier was on constantly for about a month.
