Generalnie to IARU nie zaleca beaconow poniżej 14MHz, z czym bardzo mocno się zgadzam.
Już kilkakrotnie odpalenie nieskoordynowanego beaconu powodowało zamęt na całego np. na częstotliwości polskich radiotelegrafistów współdzielonej z MF-runde i kilkoma innymi grupami.

HF beacon coordinator and subject to review by the subsequent triennial regional conference. Normally any such project would be for a limited period.

The conference agreed an exception to the general rule, in the case of DK0WCY’s transmissions on 3,5 and 10 MHz. There is a possibility of extending the DK0WCY service by time-sharing its frequencies to provide (say) near-real-time MUF data from other locations. Anyone wishing to explore the possibility of such a development should contact the DARC HF manager (and DK0WCY team leader), Ulrich DK4VW.

While the decision of the conference did not specifically refer to 1.8 and 3.5 MHz, my personal understanding is that beacon operation should also be discouraged on those bands. An earlier Region 1 resolution stated that long- running beacons should not be established on 137 kHz.

If you are interested in designing or operating beacons, there are other possibilities on other bands. In particular:

(1) The construction of beacons for countries which are not currently covered and where local operators are not in a position to build a beacon.

(2) Beacons that share a frequency (similar to the existing IBP/NCDXF network), thus economising spectrum.

(3) Designing and constructing more technically advanced beacons to replace an earlier generation of beacons. We should always recognize that there are already many beacons and our frequencies are limited. Accordingly, we have always to ask ourselves, before beginning a new project, what is its purpose and what will it add to our hobby.

It is recommended that HF Beacons may be established on the 1,8, 3,5 and 7 MHz band in the regions of Africa south of the Equator. (REC/99/LH/C4.1 – Lillehammer 1999)
