[Elecraft] RFI Snapshots wanted...
Hi, I have added an informal and unscientific survey asking if you have RFI at https://www.nk7z.net Please take it if you have time. It is a single question asking if you have RFI. It is two posts down on the right side. Sorry for no direct link to it, it is on the sidebar. Also, if you have any screen shots of KNOWN RFI sources, please send them to me directly at my email address and I will include them on the RFI snapshot page at https://www.nk7z.net/rfi-snapshots/ -- 73s and thanks, Dave (NK7Z/NNR0DC) https://www.nk7z.net ARRL Technical Specialist ARRL Volunteer Examiner ARRL OOC for Oregon __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] RFI Snapshots...
That is a very good idea, and I have, and if I get sound with an SDR image, I add it to the site... As you said though, bandwidth, etc., tend to make things sound different depending on who uploads. The real useful thing about the spectrograms are that they can be used as a site survey tool as well. The snapshot page was basically and offshoot of this page: https://www.nk7z.net/sdr-rfi-survey-p1/ which uses an SDRPlay RSP-1 as the SDR engine for a way to characterize, or survey your RFI environment. I ended up with a lot of spectrograms as a result of the site survey page, and it occurred to me they might be useful to others in IDing RFI... Now there are almost fifty different shots of RFI there. 73s and thanks, Dave NK7Z https://www.nk7z.net On 07/06/2018 05:18 AM, Al Scanandoah wrote: Dave Have you considered including sound clips with the snapshots as well? Being able to see *and* hear the RFI can go a long way toward making a positive ID. Of course, RX mode and bandwidth info would need to be included as well. 73 - Al, K2ZN __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
