Re: [IRCA] [NRC-AM] Modem Noise update

[Earl Higgins <earlthenut@xxxxxxxxx>]

Have you tried those ferrite doughnuts you clamp around any cables coming into or out of the interference generating device? I think they call them RF chokes. I ordered a small bag of them from one of the online electronics dealers, put them on every device I could think of in my house, including all the cables to and from my Ten-Tec RX-321 computer-controlled HF receiver, and the QRN went down significantly (but not completely). Well worth the small amount of money and time. Good luck!

I checked today and yes the modem noise is still there, just less with the shield. I have hooked up a switch to just click it off when I want to DX. I can forward my calls to the cel phone so I will still get them. I will have to come up with something else. Maybe there is a dual Modem out there that does not QRN. If not, I will just have to turn it off. Not convenient but it works. 
At least the cable creates no noise. I also have an idea, the QRN may be getting into the power.
