Strobe_noise_1

Hash was fairly easy to get rid of with a choke. There are very very sharp 100 milivolt, 75 milisecond spikes that are making power leads radiate like an antenna. Fooling with capacitors in a pi-network has things pretty good where noise is only heard on lower VOR frequencies, but not good enough for us. His scope probe connected to power supply (not to scope) completly eliminates any noise on radio?? Art is digging up info on probe.
