This has been a good thread-- a couple more sources I lost hair over.
-- those darn touch-on/ touch-off lamps. My wife had about 5 of those in the house. Down to one. 200khz up to about 60mhz
-- a particular brand of multi-stage battery charger/float "converter" in the travel trailer or motor home. Its the OEM unit in 90% of the newer trailers and motor homes sold. It took a major effort to find, since it was soooo strong, it would break squelch on my 70cm FM mobile a block away. It just swamped my whole property. I couldn't find it with signal strength walk-around. Finally, I tripped all the breakers in the panel, then powered each circuit up until I came to the 30amp breaker feeding the trailer power..... ah ha. Replaced with a name-brand unit-- silence was golden.
-- various consumer wireless routers, port switches, et. al. Linksys are the worst, but I haven't found any that didn't create spurs somewhere in the ham bands, clear up through 2 meters. Replaced my main switch with a Cisco 24 port commercial unit off of ebay for $60, and a Cisco commercial wireless access port-- end of those problems.
Not every noise solved, and like others reported, new ones keep showing up. On 10/13/2010 8:23 PM, David McKenzie wrote:
Check out this video of the noise I get on 2 meters. It comes up well over 20 over on some days, and a few weeks ago I heard a football game on the carrier. Escalated it to Comcast who is very certain it isn't them but is being very helpful in helping me track it down. It's strongest horizontally, and it's definitely not coming from here, and is strongest in a certain direction as identified by watching it while spinning the beams. It also drifts up and down the band but repeats out about 200kHz. http://www.youtube.com/watch?v=ZKKhySrO5Kw _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
