The construction of the NVIS
antenna was no problem.
I built the antenna following this pdf document
But due to very difficult local propagation conditions (see Ionosonde Pruhonices protocol
) no HF QSO was possible.
Relais Kahlenberg could be reached in the morning by Handtalker 5W at noon 20Watt and a X50 where necessary for good
From about 1300 UTC on we had more and more italian and russian stations on our NVIS antenna (40m), but sending was not successful. My noise reduction system NEIM-1031
worked surprisingly effective. At 1500 UTC we stopped operation.
