First 40 MHz Crossband contact between Ireland and Norway - 28th June 2019

On Friday the 28th of June 2019, Lloyd EI7HBB in the west of Ireland managed to complete a 40 MHz to 28 MHz cross band SSB contact with LA4UOA in Norway, a first for the new 8-metre band.

EI7HBB was running 4 watts on 40 MHz from one of the Ukrainian transverters into a home made 2 element Moxon in the loft space of his house. He was listening to the LA station on 28.400 MHz.

Lloyd reports that LA4UOA was 5/9 on 28.400 MHz while he received a 5/2 report on 40.250 MHz in Norway. The distance was 1108 kms.

What was interesting about this contact was that 50 MHz didn't seem to be open at the time. The maximum usable frequency (MUF) had reached as high as 40 MHz but not 50 MHz.

This shows the value of the new 40 MHz band. It's a long way from 28 MHz to 50 MHz and by having a band in between ten and six metres, it will give a better idea of where the maximum usable frequency is.
