I don't want to say it was the Linksys network switch -- but "it was the Linksys network switch".
Just replaced it with a Netgear switch with a metal enclosure (GS305, for those keeping score at home). Plugged it in, plugged in the network devices (VoIP phone, laptop), and went downstairs to scan the bands for potential issues. The Linksys, as you may remember, produced noise every 30kHz or so on 40m (worst) and also on other bands. It was S9+ noise. Really irritating. The Netgear produces no such noise on 40m or any other band that I can discern. So, it's nice to have this resolved without having to re-wire the entire house or search out another part to replace. :-) Thanks for all of your help -- and I highly recommend the Netgear GS305 if you are looking for a 5 port network switch! 73 -john NE4U ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
