The best way I have used to test the effectiveness of noise blanker is try to use the radio in a house with a common incandescent lamp dimmer nearby the antenna connection. Use a wire antenna placed near the lamp or wiring of the dimmer circuit if necessary to increase the coupled noise.
The power line frequency zero crossing pulse width modulator (severe contant buzzing sound) of the lamp dimmer noise will be almost completely supressed if the noise blanker circuit is working properly GL 73, Bob Johansen WB2SRF K2 S/N 5622 _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
