Baking crystals to restore them has been described on this and several other lists but I can't find any details. I need to know the temperature or at least the limit. Does anyone here know? --

Thanks jim, but first, is/has this topic swung to dealing with ignition noise only? For an SX-117 ??? . interesting discussiuons, but what is the scope of it? Help..I’M lost …. again. don

Well I would disassemble the carb, clean it, and air blow it outside, then bring it in and put it back together on the kitchen table. My present wife says, "over my dead body"! When I mention it the

True: my BC-342, BC-312, etc. manual suggests routing the noise antenna near the engine of the vehicle whose ignition noise is troublesome. Maybe when the receivers weren't used in vehicles where that

I see, since the two noise signals are coherent its possible to cancel it by phasing. Would work on man made noise where the signal and noise can be separated. -- Richard Knoppow Los

Hi, Richard, The system I described is not the same as the noise blanker internal to the receiver. The circuitry that the Signal Corps used, and that has been implemented by MFJ and others, works

Just wanted to say thank you to Jim K9AXN, Walt and the rest who helped me along the way!? ?The radio is finished and really runs and looks great! It was a massive amount of work to get the rig

DonRead the enclosed excerpt from TM 11-310.? The first page shows the noise antenna circuit and lists all design changes to the series of receivers.? I would think that the noise antenna would be

A further note: The purpose of the blanker is more to prevent pulse noise from desensitizing the receiver by being seen by the AVC as signal. Although the noise pulses may be very short their

The reverse phase cancellation is not how I understand the blanker to work although I think there are noise eliminators that do work this way. My understanding is that the signal from the noise

Maynard, your theory sounds mostly good, but we need some details on what is called an antenna; will it work with my 10 feet of haywire antenna? Sent: Monday, June 10, 2024 2:22 PM To:

The operation of a noise antenna and associated circuitry are independent of the nature of the noise, whether or not it's periodic and whether or not it's random. Ideally, the signal antenna would

Mike and all, there must be quite a different scheme when trying to reducing Lightning storm “static” as opposed to very local noise or nearby bad power line noise, or your own light dimmer noise.

Richard , do you drive your engine at one speed? Sent: Sunday, June 9, 2024 9:16 PM To: [email protected] Subject: Re: [HallicraftersRadios] SX-117 noise limiter behavior Well,

Well my own contribution to this is spring, 1967, I owned a 1963 Austin-Healey Sprite Mark II (not the 'Bug Eye' one).....948cc engine.....needed to be rebuilt, so one night after work I pulled

I am seeing a picture in my mind of a kitchen with motorcycle parts all over. Smells strongly of gasoline and kerosene. I don't remember where this comes from. Some low life I once had as friends

It IS periodic, not random. Each noise pulse has a definite signature. It is well above average random noise. A noise blanker of any sort desensitizes the signal channel during the noise pulse. In

Tom, Kinda like rebuilding a carburetor on the kitchen table! LOL Bob W4JFA [email protected]> wrote:
