No words of wisdom, Bruce. but wanted to offer my condolences. The dang pager interference we've got is about to drive me to drink. which is probably the ONLY nice thing I can say about it.
Hope you find your demon! 73, Mike WM4B _____ From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Bruce Coates Sent: Monday, April 26, 2010 10:27 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Interference from local 600 kHz radio station. I snowed here yesterday, does that count? ;-) In all seriousness so far we only know that it "comes and goes". We've yet to find a clear pattern of day/night, week day/weekend (it's on an office tower) , hot/cold, wet/dry, etc. yet. We hope to do a bit of a "fox hunt" at the sight later this spring. 73, Bruce ----- Original Message ----- From: "Joe" <k1ike_m...@snet. <mailto:k1ike_mail%40snet.net> net> To: <Repeater-Builder@ <mailto:Repeater-Builder%40yahoogroups.com> yahoogroups.com> Sent: Monday, April 26, 2010 8:16 PM Subject: Re: [Repeater-Builder] Interference from local 600 kHz radio station. > There was a 6 meter repeater here in Connecticut that was receiving > interference from an AM station several states away that was > broadcasting on 1000KHz.
