I have an S9+ noise level on all the HF bands. I've suspected my computers, fluorescent lamps, BPL, but I'm not certain. It sounds/looks like this. I've turned off all the computers and other appliances, alarm clocks, etc. There is no change in the noise. Don't overlook a UPS...my APC makes garbage at periodic intervals across the band, varies with input voltage -Bill |
