A 49m Bandscan

As indicated in an earlier blog, a planned scan of the 49m band was made a few nights ago ... one at 0400Z (10PM local) and another at 1200Z (5AM local). Both had a decidedly different flavor. Frankly I was surprised at the number of broadcasters and especially the number from Asia, China mainly, heard in the morning scan. One information source I found indicates that most of the strong shortwave signals from China are more designed for jamming than for program content.

My initial impression was that many of the more interesting low power targets from Central / South America and Africa may be a thing of the past but I may be wrong. The 'news' page, of the World Wide DX Club, seems to indicate that there are still lots of juicy targets out there if you are willing to put in the time to look for them, as many seem interested in doing. There also seems to be a larger variety of DX targets available in the higher bands such as 25m and 31m.

For the most part, these broadcasters don't fool around with QRP, and their signals are pretty dominant. Conditions of late have not favored Europe or Africa so there may be more activity from these regions than I think.

The following stations were logged with the Perseus SDR along and the 10'x20' loop / Wellbrook preamp, looping E-W, at 0400Z:

The number of broadcasters using remote sites is also surprising. It seems that the relaying of program content for others is big business and for many countries, much cheaper than running their own 250kw stations.

Some links that I have found very useful for identifying SW BC stations:
