Rick, there are irregularities in my noise - and in the previous utility line noises I've had at my QTH - that prevent any predict-the-exact-time-of-the-noise-spike-in-advance algorithms.
OK forgot the Kalman filter. Back to brainstorming Plan B: In the 1950's I believe Collins Radio had a scheme with the KWM-2 mobile radio where they had a VHF receiver at 35 MHz IIRC that picked up ignition noise and triggered the noise blanker. I am wondering if something like that could be adapted using a VHF Yagi aimed at the offending power pole. Plan C: Same principle as the Collins scheme, except: The NB would listen in the band from say 1775 to 1800 kHz for purposes of generating the blanking pulses. There should be no signals in that band. (At least I've never heard any here; what is this band allocated for anyway?)
