It was only on the 10th of January 2021 that Dragan made the very first contact on 40 MHz with EI4GNB in Ireland.

Condolences to his friends and family.

First contact between Ireland and Croatia on 40 MHz - 12th Jan 2021


During an extensive Sporadic-E opening on the 12th of January 2021, Tim EI4GNB near Dublin, Ireland completed a successful FT8 contact with Dragan 9A6W in Croatia, the first EI-9A contact on the new 8-metre band.


The FT8 contact was completed on 40.680 MHz which is in the middle of the 40 MHz ISM band (Industrial, Scientific, Medical).

As the screenshots above from 9A6W, the signals were quite weak.

The screenshot below shows how EI4GNB was not only hearing 9A6W in Croatia on 40 MHz but also S59F and S50B.


This is a map of the contacts for EI4GNB from PSK Reporter...

The contact between EI4GNB and 9A6W was in the region of 1,974 kms which is a standard distance for single hop Sporadic-E.

40 MHz activity... It was also great to see that a number of stations were listening on the 40 MHz band today. These are the stations that heard S59F on 40.680 MHz on the 12th of January 2021...

Croatia becomes the latest country to grant access to the new 40 MHz band - Dec 2020


We now have welcome news that Croatia has joined the small number of countries that has allowed operation on the new 40 MHz (8-metre) band.

In a message by email, Dragan, 9A6W writes...

In April I have applied for an experimental license to transmit on 40 MHz hoping to be QRV for the E-sporadic season. To make a long story short, national telecom authorities have just issued me an experimental license for 8 m band, 40,66-40,70 MHz. I am QRV with FT-897 (100 W) and a dipole antenna at the moment. 

The license is valid for a year and then it could be renewed. There are rumors that some other stations will follow my example.


I received EI1KNH and OZ7IGY beacons this summer (2020) on many occasions. I am monitoring 6m these days for any openings (TEP or Es) and would like to be in touch for a possible QSO. I will use 40,680 for FT8.

Croatia is now the fifth country in which it is possible to operate legally on 40 MHz. Ireland, Slovenia & South Africa already have allocations on the band while Lithuania is willing to allocate spot frequencies for experimental purposes.

The frequency allocation that 9A6W has obtained is from 40.660 MHz to 40.700 MHz. This 40 kHz wide slice of spectrum is referred to the Industrial, Scientific & Medical (ISM) band.

There are a number of ISM bands but this is the one nearest to 40 MHz. In many countries, much of the low band VHF spectrum is allocated to military or other services. Licensing authorities may be unwilling to grant radio amateurs an allocation that hasn't been agreed internationally. 

The ISM band at 40 MHz is an exception and it might be a good way for other countries to proceed i.e. individual licenses in the ISM band.

Range... As the map shows above, 9A6W is at an ideal distance for Sporadic-E openings to Ireland and Lithuania. As the most southerly 8-metre station in Europe, there is a possibility of some TEP openings to South Africa or perhaps via F2 near the peak of sunspot cycle 25.

The distance to Slovenia is about 200 kms which might be spanned by tropo or even meteor scatter during the major showers.

Update 3rd Dec 2020... 9A6W reports that 9A2WB heard his JT65 transmission over a distance of 114 kms.
