ARLA/CLUSTER: First 40 MHz Amateur Radio Propagation Beacon On The
Quinta-Feira, 16 de Agosto de 2007 - 16:21:42 WEST
First 40 MHz Amateur Radio Propagation Beacon On The Air
Ivan OZ7IS has announced that the first 40 MHz Amateur Radio propagation
OZ7IGY is now on the air on 40.021 MHz
The European Radiocommunications Office (ERO – now ERC) of the CEPT launched
March 1993 Phase II of a Detailed Spectrum Investigation (DSI) covering the
frequency range 29.7 - 960MHz.
The results were presented to Administrations in March 1995 with the
of facilitating a European Table of Frequency Allocations and Utilisations
be implemented by the year 2008.
Regarding the Amateur Radio Service the DSI Management Team recommended
other things) that 70 MHz to be considered as an amateur band AND:
in the vicinity of 40.680MHz be considered for amateur propagation beacons".
During the IARU, Region 1, C5 meeting in Vienna earlier this year David,
told that the RSGB were planning such a 40 MHz beacon. I promised him to
similar initiative when returning to Denmark.
In July the GB3RAL 40.050 & 60.050 MHz VHF beacons were approved and shortly
after OZ7IGY received the permit to operate on 40,021 MHz.
On 26th of July (after paying the licence fee) at 18.20 UTC OZ7IGY became
40,021 MHz near Jystrup (Ringsted), JO55wm, 97 masl / 5 magl.
The antenna is a dipole heading 255 / 75 degrees. Will shortly be changed to
The output to the antenna is 22 Watt keying in F1A (frequency Shift Keying)
according to the IARU, Region 1, standard. 250 Hz shift.
The "licence" is valid for a year and the results of the experiments are to
reported to the ITST.
The "licence" is "experimental" on a non-inteference basis and will not
a precedent for any other kind of amateur radio activities in this part of
Please report to DX-summit whenever you hear the beacon. Then we can collect
data for the report to ITST and may be able to argue for a renewal of the
licence next year?
In 1993 the head of ERO was David Court, EI3IO (G3SDL, OZ3SDL etc….) I have
feeling that without his "stamp" on the DSI report we would not have had the
ever increasing access to 70 MHz throughout Europe or these 40 MHz amateur

P.S. We are looking for circulators/ Isolators for the 40 and 50 MHz beacons
avoid backwards intermodulation in the PA stages. We are covered on all
bands but circulators for these frequencies are hard to find as surplus
equipment! Can anyone help? Please!
GB3RAL now licenced for 40 and 60 MHz (7th July)
Denmark to get 40 MHz beacon (19th July)
