Title: RFI discussion was Sat_DXer's Beacon Log
Post by: sat_dxer on September 06, 2018, 1356 UTC: Like something out of On the Beach random dits (S, I, E, NI) from 1350z noted on 9907kHz 6 Sept 2018

Post by: Teotwaki on September 06, 2018, 1535 UTC: Did you mean the movie called "On The Beach"?

On the Beach is a 1959 American post-apocalyptic science fiction drama film from United Artists, produced and directed by Stanley Kramer, that stars Gregory Peck, Ava Gardner, Fred Astaire, and Anthony Perkins.[2] This black-and-white film is based on Nevil Shute's 1957 novel of the same name depicting the aftermath of a nuclear war.[3] Unlike the novel, no blame is placed on whoever started the war; it is hinted in the film that the threat of annihilation may have arisen from an accident or misjudgment.

Likely a local RFI source, hopefully not a coke bottle :)

Post by: ThElectriCat on September 10, 2018, 0329 UTC: I have one of those too (i guess everyone probably does). it really is amazing how much noise such a low power device can make. on certain frequencies in the 280 ish KHz range, I can actually hear the packet framing manifested as FSK. It was really fascinating for a few minutes, until I unplugged the router and the noise floor dropped 10 db.

I substantially reduced QRM from ethernet by changing to shielded cables, and getting a new switch.
