Hi everybody;
My next door neighbor just purchased a new 40"+ flat screen TV. When He turned it on, my little K2 just about jumped off the operating table!
The EMI is pretty bad. After thinking about a non violent cure for a while I discovered a little mod to my KNB2 that turned out to really work.
The addition of a 0.1Uf cap between the emitter of Q2 and ground proved to be quite effective in taking the interference noise level down quite a bit.
It's not gone entirely but is nowhere near as bad as it was.
The mod may be found in the Tech. notes section, K1/K2 mods, "excellent index of customer mods" kept by Sverre LA3ZA. To continue, LA3ZA unofficial guide to K2 mods, general mods for any K2, KNB2, noise blanker knb2, Increase low threshold sens. BY Stefan DL7MAJ. Whew!!
Maybe this mod will work as well for others, I hope so. Thanks Stefan!!
Best regards, Bob K7HBG
