Hello friends
Lately all of our broadcasts have been without mishap. The Saturday 2300-2330 UTC is, however, "interesting" because of the noise that has been co-channel the past few weeks. It sounds more like jamming than data, but this does not rule out that it is some sort of data. The signal seems strongest via SDRs in Michigan (see screenshot below), but given the nature of shortwave propagation, it is not necessarily from that area. And the noise does not seem to be daily, although I have not yet determined the exact schedule.
Voice of Korea from North Korea is on 7570 also at 2300 UTC, which usually prevents reception of Shortwave Radiogram in Europe. This noise does not seem to be jamming against that. And it is possible that the noise is jamming from Cuba against, maybe, a former program on WRMI. But signal is stronger than any Cube jamming I have heard previously.
WRMI is now aware of the noise. If you have any ideas as to what it is, and from where it is transmitted, please let me know.
A video of last weekend's Shortwave Radiogram (program 289) is provided by Scott in https://www.youtube.com/watch?v=eSJopVvIJNg Ontario (Friday 1300 UTC). (See also video of sidewalk reception in Moscow of The Mighty KBC, 15770 kHz from WRMI.) The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
