Hi Elecrafters - Today I took delivery of K2 #892 and very happy to have it in the shack after selling my #4958, I think it was, years ago... if anyone has it I'd like it back please). This #892 has a "static sounding" scratchy/raspy noise on top of CW signals. It sounds similar to what you'd hear from an oxidized audio frequency pot. The strength and presence of the noise is proportional to the incoming CW signal strength.
The rig is running from a clean, large high current capacity battery so I'm sure the supply power is good. The noise occurs across multiple bands. I get the sense it's something in the audio chain. The installed KDSP2 digital audio filter has already been put in bypass mode and the scratchies persist. Before I continue debugging I wanted to see if anyone had suggestions about what components to target. Thanks, -Andrew / NV1B .. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
