| Media Projector RFI source on 20m | NQ0T | on 24/2/16 |
| I have been plagued with a severe RFI problem every since I moved into this home. I bought the home with an installed Optoma media projector. The problem: Broadband interference (noise) at S8 on 20m from end to end. Similar on other bands, diminishing at longer wavelengths. The 40m band was not nearly as bad. How I found it: Set a cell phone on the radio connected via facetime with another cell phone. Started shutting off breakers. Oops!, Don't shut off the router and internet and loose facetime :-) When I shut off the breaker to the media room the noise stopped....AWESOME!!! Went up the media room and started unplugging things until I found the Optoma projector to be the culprit. Short term fix: unplugged the projector. Ham radio rules! Long term fix: searched the web. Nothing found tied to projectors. Open to suggestions on what is causing and how to fix. Hope this helps others. I'm thrilled to have a more respectable noise level again. Able to hear signals on 20m again. 73 de NQ0T, Robert |
