In the August issue of Germans´s "Funkamateur" there was an article about this topic.I´ll keep the article short:
He measured L3 and found out that it had 80µH(he built it correctly according to the manual) instead of 40µ Henry.
So I also swapped L3 but my noise blanker was still doing nothing against the cow fences. In an e-mail he suggested replacing C12 to22nF.I haven´t done this modification yet, but I´ll do it. Our alpine meadows are full of cows at the moment and I mainly use the K2 for my portable operations, so´ll be glad to get a hint
