[Elecraft] K2 Noise Blanker Modifications

[Ralph McClintock]

Hello,
 Does anyone have any ideas about level and pulse width modifications for the K2 Noise Blanker. My problem is neighbors electric fences and corrals. They were built with aluminum, copper and steel wire intermixed and have over 300 twisted connections. I have replaced the old solenoid type pulser with a solid state unit. The pulsing is not even touched by the KNB2 in any configuration eventhough they are about 40db over 9. I can tell the NB2/LWR position is working but does not do anywhere near what is required. On 160-40 my primary bands of interest it's really bad. 
Tnx & 73's,
