![]() "Ian Jackson" wrote in message ... In message , homepc writes I'm running a 6v 300ma adapter to run my Sangean ATS800 radio. I was wondering if applying a couple of ferrite chocks like this to the DC power cord would eliminate any humming noise created by the adapter. http://www.piurl.com/p/22mW The humm is not very loud, but it's noticeable. I know batteries are the best solution, but in this case it's more convenient to use the adapter. Presumably you are referring to hum coming from the radio, and not directly from the power adapter. However, either way, these chokes won't make a scrap of difference. -- Ian So you are saying the RFI humm created by the wall wart is not being directly transmitted by the power cord? I have a bit of excess power cable bound up behind the radio and I notice if I move it around it creates a variable humm. The fact that it is bound up there makes no difference, the adapter interference was always apparent. |
