I see that on the LA3ZA modification pages there are some capacitor changes
that change the time constants in the KNB2. Unfortunately the links to the

My questions to the list are, will changing C11 and C12 (value unknown)
likely to help with the electric fence QRN and, if so, will this compromise
the KNB2 with other types of noise? Has anyone else performed some other
modification which may help with this type of QRN?
Any help would be much appreciated.

Yes Allan the mod does help in this respect, I found when I moved to a
nice quiet location in France, I was also plagued by QRM from a local,
badly installed and maintained electric fence. However my modified noise
blanker certainly helps, but doesn't completely cure my problem, it
seems to vary from day to day and with wet weather of course. The mod
certainly makes a difference to this type of qrm and is worth doing.
