Ten meter beacon band spans 28.100 – 28.300 MHz (photo by author)
Recent 10 Meter CW Beacon Activity
Mario Filippi, N2HUN
The 10m band has been coming alive lately and it’s time for all hams and SWLs to take advantage of it. For several years I’ve been listening to 10m beacons with mediocre results but this has all changed over the past few days with loggings of European beacons running as low as seven watts.
These amateur radio beacons can be found from 28.1 – 28.3 MHz, sending out their callsigns in CW along with other information such as power output, grid square, antenna type and other tidbits of interesting information. Most USA beacons are heard from 28.1 – 28.2 MHz while international ones inhabit 28.2 – 28.3 MHz. Some beacon ops will request QSL card reports the old school way via mail. I’ve written out a few already, bringing back fond memories of my early days as a ham and SWL.
Over the past few days at my central NJ QTH, using an Airspy HF+ Discovery and a ground mounted 31 foot vertical, here are some of the DX beacons logged:
IZ8RVA, 28.239 MHz, 1230 UTC
OH9TEN, 28.265 MHz, 1253 UTC
LA5TEN, 28.237 MHZ, 1300 UTC
OK1AR, 28.249 MHz, 1214 UTC
DA5TEN, 28.237 MHz, 1219 UTC (7 watts, vertical antenna!)
DL0IGI, 28.204 MHz, 1251 GMT (50watts)
Note that most signals were 449 with QSB so a quiet room, a good pair of headphones, many cups of good hot coffee/tea and a heap of patience are needed. Beacons will send a continuous CW tone as a preamble while others will transmit a series of V’s (…-). So, spin that VFO dial up to 10 meters, a band which comes alive as sunspots rise. If you are a QRP’er, this comes as good news since this band is great for those who love to run peanut whistles.

In search of benchmark signals: The International Beacon Project
If you – like yours truly – like to tinker with antennas and radios to get the most out of them, you likely have your own set of reference stations. If this is a new concept for you – reference stations are whatever stations you deem apt to check propagation, the general function of your radio, when trying to improve reception or comparing radios… They are ideally always on when you need them and come in various strengths and distances on several bands from all over the world. Traditional sources for that are of course time signals and VOLMET stations on HF, even though the latter are giving you only two 5-minute slots per hour for testing reception from a specific region and the former have their own specialities here in Europe:
A typical scene on 10 MHz, captured at home 30 minutes after the full hour: BPM voice ID from China mixed with something else, then Italcable Italy kicks in on top of some faint murmur possibly from Ft. Collins, in winter some South American time stations may stack up on that together with splatter from RWM 4 kHz lower…
A reliable source of grassroots weak signals is particularly desirable for me because I enjoy proving and comparing the practical performance of radios at “the dike”, a QRM-free place on the German North Sea coast. In the absence of manmade noise and the presence of an ocean adding 10dB of antenna gain, finding benchmark stations with “grassroots” signal levels turned out to be a different challenge than it used to be: With somewhat sizeable antennas the stations tend to be (too) loud there, even with the baseline ionospheric conditions under a spotless sun in its activity minimum. In short, my old benchmark stations didn’t work so well anymore and I had to find something new. Continue reading →
