Guest Post: 40 MHz band on 7th & 8th May 2021 ...by F1EIT

Thanks to José, F1EIT for the following information which forms the basis of this post.


Friday May 7th was surely a great day for the S55ZMS beacon with the first 40 MHz spots but also
for 8m Sporadic-E activity that increased on the 8th .

Joan EA3ERE put the first spots (PI4) for EI1KNH on the 23rd of April but I heard nothing on CW.

On the 7th of May, Michel, F6HTJ heard the EI1KNH beacon on CW but I still heard nothing!

Finally today the 8th of May, both Michel and myself heard the EI1KNH beacon on CW and we also were able to hear the S55ZMS beacon in Slovenia at the same time.

I have a lot of QRM in the 40 MHz ISM band (Industrial, Scientific, Medical) and sometimes also on the beacon frequency.

I am still using my 50MHz Hentenna with an ICOM 575A. I am also working on a 40MHz wire halo based on the G3XBM (10m) design and am also looking at building a YU7EF 4-element Yagi.

José, F1EIT
