Storm and more storm


Yes!  tonight the rain and wind stopped
So again lowered the beam and found the cable gave high SWR  on a dummy / power meter.
The SWR  raised when tuning up to 29MHz  something was wrong.
Now replaced  and SWR is 1:1.5  28   to 1:1.1 29  on the Steppir
I could tune up the band with the Steppir  what I couldn't do before  in October in the high sunspots  and JA  XE  W in the FM part > 29MHz.

Anyway I am a bit ready for the ARRL10    if the WX stays a bit quiet.
The total cable loss  over 60m  ( 30m 50Ohm  26m 75Ohm  )  
5W in  3.8W out   -1.19dB  28MHz
I can live with that.

also 50 to 75 Ohm  gives   SWR 1:1.5 in worst case  1/4 wave I believe









Hard to prepare for the ARRL this way  hope for some breaks  Friday
I have another 4 ele beam  or I could ad 2 extra directors as a DX reading glass for the Steppir..
But we have to wait for the storm to lay down ..

Hallo Jaap, het lijkt er niet op dat we wat kunnen met de antenne's. Het is hier ook nopg KUT weer, de regen komt met bakken uit de hemel vallen. Grappig ik heb exact dezelfde rotorclock hier van UKW Technik. 73, Bas
