Comments:

Spent the first ten percent (6 minutes) of the 
session on 7 MHz with Gert PA3AAV as the single 
station. Then found Rich NN3W on 14 MHz stronger 
than most Europeans. There was serious blanking 
of most of Europe by the Es-layer, but its MUF 
was not very high up. Nil on 21 MHz. Solar X-rays 
were at B1.5 throughout the session and there was 
slight Aurora. Went back to 7 MHz for the braking.

Did walk around with the new IC-705 as spectrum 
monitor for EMI, and found a hidden door between 
two apartments, where excessive nois was coming 
from. It probably deals with the electricity of 
the block, as there seemed to be a GSM-antenna 
to pass the data to the el-grid power-company. 
Have to find out and maybe donate some ferrite. 

Also tested a FTDX10, but there seems to be a 
parasitic oscillation in the final above 1.5 : 1 
SWR (the final transistor is UHF-type RD70HUP2, 
strangely a 70 watts type (with good reserve 
for extra power on HF, but maybe not for IMD?).
Parasites/spurious is a different matter still. 

Cheers/73, Zaba OH1ZAA  #1856 CWops
