On the 9th of August 2020 at 10:14 UTC, Borut S50B and Ivo S59F managed to complete a contact on 40.680 MHz for the first contact on the new 8-metre band between two Slovenian stations.
Even though the distance between each of the stations was only about 20 kms, this was over a very poor path with a lot of high ground in the way. Signal reports of 5/3 and 5/5 were exchanged on SSB.
For this first S5 to S5 contact on 40 MHz, S59F was using an ICOM IC-7300 with 100 watts into a dual band 50 MHz / 70 MHz Yagi. It's probably safe to assume that this antenna had no gain on 40 MHz so would be no better than a dipole for the band.
S50B was also running 100 watts from an ICOM IC-7100 but into a dedicated SIRIO vertical for 8-metres.
Even though the Slovenian licencing authorities allocated a slice of spectrum at 8-metres back in 1998, it's only in 2020 that S5 stations have started up on the band. This is largely in response to the new 8-metre allocations in Ireland and Lithuania.
S50B had already worked EI4GNB and LY2YR for S5 firsts at 40 MHz so the contact with S59F was his third first for the band.
As can be seen below, the 8-metre allocation in Slovenia is from 40.660 to 40.700 MHz, the exact same as the ISM (Industrial, Scientific, Medical) band.
