Is it possible that the interference is being generated not by the transmitter but rather by bad connections in power lines or utility pole guy wires nearer to you? Some driving around with a portable radio with loop stick antenna might reveal or confirm the location of the signals. Hams in

I find it very Surprising that someone just happens to discover such a prized card, with my average 160m score I would never have "misplaced" such a valuable card.Also, given that the card was apparently misplaced, and that it is not in the uploaded logs too, I start to smell a rat.Not to

As a one-time broadcast engineer at a high power FM station, I believe whoever in responsible for performance will want to know what is happening --  management, not so much. Reports going back several years raise questions, though. A search says that CKTB is a 10K/5K day, night station.  Not

Hi Dave, I too was shooting blind when I called CKTB this morning. I was able to leave Bonnie Heslop a Voice mail message. Bonnie is the News Director and Announcer at that station and she is the person announcing in my recording. I also sent them an e-mail with my contact info and link to my

Hi Roy, Numerous stations in Canada and the US are encountering the same RFI (originating from the same station near Niagara Falls). In recent years we have encountered similar RFI on 160 meters from an AM broadcast station in New Jersey as well as one in Kentucky that had spurious emissions up

Hello 160 ops, I tried a telephone call to all the numbers for CKTB, but there is no way to leave a messagee unless you know the name of someone there on the directory list. There is no receptionist to answer the phone during the day. I left my second e mail with contact information, but

My qth is St. Catharines ON. The spurious transmissions from CKTB have been occurring sporadically since the summer of 2019. The spurious signal on 1830 khz seems to occur when it is windy in the area and appears to becoming more frequent. On Friday March 20 around 0100Z the spurious signal

John and others, Yes, I now see reports from far from the station. Clearly my comments about causes local to the one nearby ham reporting interference do not apply I will listen myself tonight. Maybe some of our two trillion dollar aid package can be sent to Canada. Perhaps a mere $100,000

Good question Roy I was hearing the St Catherine station very loud on 1830, but with intermittent periods where it would dropout. This was at a time with high winds in the NE.  I suspected that it might be a problem at my shack, so I tried to find CKTB and it is on the same frequency as a

Dave and other Topbanders, I plan to do some listening from here in Western Mass, USA (Near the junction of NH/VT/MA). The wind speed here is expected to peak tomorrow afternoon at 10 MPH, maybe not enough to jangle what’s loose in Canada. Is this Saint Catherine in Quebec? Near Niagra

If any of the DXmans would be in the mood to read the facts about my "exclusion" from the ARRL, then please read my page section. Here you will find facts supported by correspondence. We all know, that the DXCC program is totally discredited by the use of remote stations situated near the DX

It is indeed true that variations in liquid soil moisture will dramatically affect ground system performance and base fed vertical impedance when an on, or below grade ground system is used. Frozen ground moisture is on a par with dry ground. This is one of the reasons for going beyond the

I'll not ask to see a scan of the card because that may not be conclusive and it's not my 'job' to decide, but I'm still curious to know the reason for a QSL card "appraisal" request if not to ask for credit. It simply does not 'compute' that a ham who has pursued the number 1 spot for so long
