Re: [Elecraft] Internet RFI Issue
Hi Sandy: QRM can definitely be a problem if you are seeing other networks show up on your computer when you have it search for networks. I'm using a wireless G router but only have one neighbor within range so staying on separate channels is no problem for us. Charter can tell you very quickly if your signal levels and s/n ratio is a possible problem just by making a phone call. Tell the cute-sounding computer who answers that you want a Tech Support Agent and she'll connect you. The agents can look at the history of your connection and tell you if it shows any abnormal noise or other signal issues over some period of time. After the agent noted something abnormal on my node they dispatched a tech out here to have a look. I have fun with Charter's computer. One time I told her that if I wasn't married I'd ask her for a date. She replied, I'm sorry. I don't understand. Sounds just like a lot of girls I've known over the years. 73, Ron AC7AC -Original Message- From: Sandy [mailto:ebj...@charter.net] Sent: Thursday, January 19, 2012 9:27 PM To: Ron D'Eau Claire; Elecraft@mailman.qth.net Subject: Re: [Elecraft] Internet RFI Issue This effect JUST might be the cause of my problems too.
