Re: SX-117 noise limiter behavior
|
Floyd Have the tubes been checked for conduction, leakage and shorts?? Are you planning to recap the radio or at least check some coupling and bypass caps for leakage?? Have you done a critical look to see if there are any signs of stress on components and the like?? Sprayed?all pots and switches with your your favorite contact cleaner? I would do all of the above before applying power, to any radio.? It will save a lot of time troubleshooting. Regards, Jim Logic: Method used to arrive at the wrong conclusion, with confidence.?

Clarify a little, do you mean a desired signal falls off that much or background noise? If its a desired signal it sounds like the blanker is blanking or blocking the signal all the time. A noise blanker is supposed to cut or blank the signal path for short periods to eliminate the effect of impulse noise, like ignition noise. Mostly to prevent it from activating the AVC and desensitizing the receiver. Don't know how its arranged in the SX-117 but it sounds like its blanking all the time.
