RichardI am recommending penetrating oil to clean and lube switches and pots.? Kroil, Deoxit and the like are effective but are also expensive.? Just trying to point out that there are alternatives

The noise limiter in the SX117 is somewhat unusual. It is a diode noise clipper, similar to the conventional limiters found in many receivers, but works at IF frequency rather than audio. It is NOT a

FloydYou originally said: "Haven't dug into this yet, but wonder what other SX-117 users see when turning on the Noise Limiter in? USB or LSB mode.? On my receiver, it's like disconnecting the

A noise limiter (usually a diode or two) clips off audio above the strength that the desired audio wave reaches. Some observers say it should be called a clipper, not a limiter. Often the “clipping

A blanker normally reduces pulse type peaks such as spark plug type pulses. Someone else will need to describe a noise limiter. Bob W4JFA [email protected]> wrote:

So, guys, where is the formal non-partisan definition of.. "noise blanker" "noise limiter" Is there a defined difference between them ? and do the terms define an intent or a specific circuit? Sorry

I had hoped that someone who has actually seen and used an SX-117 would respond.? I've only been restoring receivers for 40 years or so, but over that time I've learned that you can save a lot of

Wow. Awesome. I tried that on mine but the plates where badly scorched. Also, If you are not aware, You should run a wire from the rear section TOP terminal to the rear section bottom terminal. Use

I got lucky. Simple fix. When I got the load cap out, I could clearly see the rotor was too far to the rear. I adjusted the end play screw and centered the rotor plates and all is fine. That is when I

As far as I can see, there is a form of Noise Blanker implemented into the SX-117. Two silicon diodes, polarised by the signal from the last IF amp that de-sensitizes the input directly at the antenna

FloydHave 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

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

Haven't dug into this yet, but wonder what other SX-117 users see when turning on the Noise Limiter in? USB or LSB mode.? On my receiver, it's like disconnecting the antenna - an S9+20 signal falls

Donald, Yes, these are the ones. New to this process so is further communications handled here or offline? If offline, I don't know how to reference your email address. Steve

Thanks for posting that article!? That stuff never changes with time does it!! The original transformer is rated at 6750 (CT).....so with 12V the secondary should yield 675(RMS)? and Yes.....? The

Hi Donald, I am interested in the S-meter, the S-meter control pot on the back of the chassis, along with the Response and Selectivity knobs. Let me know what you have available. Regards Kevin M -

Using the Duncan Amps power supply designer ( /g/duncanampspsud ) I modeled the factory supply with 866As, with diodes, and with different bleeder and capacitor values. Long story

They are not available. They are reverse rotation. I ordered five caps and no e really work directly. I did find one that does work at tubes and more.com. however it's slightly smaller and will need a

I need the PA load capacitor for the SR-2000. C156 3 section Halli. Part #048-000629. I think someone else had the same need a short time ago. I cannot find the topic in the archives. Hope someone
