Re: [wsjt-devel] Another fun hash collision P97USI
For what it’s worth, I too printed that station a couple of times (and saw many, many calling him). I could see that it was P4/WE9V in reality. I’m not clear on what the ask is, Reino. I decoded many, many messages (normal QSOs) in that time frame, including others calling P97USI/P. 240226_19593028.074 Rx FT8 13 0.3 703 CT1GYD RR73; M0JUE -06 --Dennis NE6I From: Reino Talarmo via wsjt-devel Sent: Tuesday, February 27, 2024 3:34 AM To: 'WSJT software development' Cc: Reino Talarmo Subject: Re: [wsjt-devel] Another fun hash collision P97USI Jon, It would be interesting to know whether you have decoded a message containing P97USI/P within 231900 and 232530 and what that message was? 73, Reino OH3mA From: Jon Anhold via wsjt-devel [mailto:wsjt-devel@lists.sourceforge.net] Sent: Tuesday, February 27, 2024 2:50 AM To: WSJT software development mailto:wsjt-devel@lists.sourceforge.net> > Cc: Jon Anhold mailto:j...@anhold.com> > Subject: [wsjt-devel] Another fun hash collision P97USI 231900 16 0.4 909 ~ BG2AUE -25 Aruba 232530 5 0.4 909 ~ JR3UIC RR73; JA7WND +06 DPR of Korea Maybe some logic that checks "am I *really* North Korea?" would be good :) 73 de KM8V Jon ___ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
Re: [wsjt-devel] Another fun hash collision P97USI
While I do agree, there aren't too many clues for the operator who is listening apart of not trusting any rare DX. I saw that NK call yesterday in 10m mixed with the Aruba one. I answered to both, once or twice. Both looked like legit grids and feasible callsigns. In the last weeks I'm getting far more false decodes than it used to be in a whole year. Many R in the messages and grids that doesn't match the callsign or places where is unlikely to find anyone far from everything or maritime routes. Not saying that it's related or it's due a bug, just making an observation about it.

The new code number system send at set period/timestamps by H40WA on FT8 verified at website, looks good for the job. 73 vk4tux On 27/2/24 23:33, Joe Taylor via wsjt-devel wrote: Hi Jon, On 2/26/2024 7:50 PM, Jon Anhold KM8V via wsjt-devel wrote: 231900 16 0.4 909 ~ BG2AUE -25 Aruba 232530 5 0.4 909 ~ JR3UIC RR73; JA7WND +06 DPR of Korea Maybe some logic that checks "am I *really* North Korea?" would be good :) That logic is you, the operator.

Re: [wsjt-devel] Another fun hash collision P97USI
Jon and all, For your information, we have already made two modifications to our WSJT-X code that significantly reduce the likelihood of 10-bit hash collisions occurring. The few OMs who are currently testing this have all reported positive results. These improvements will be rolled out to everyone with the upcoming Release Candidate 4. In the example you reported, however, it also looks like a false decode to me. 73 de DG2YCB, Uwe German Amateur Radio Station DG2YCB Dr. Uwe Risse eMail: dg2...@gmx.de Info: www.qrz.com/db/DG2YCB Am 27.02.2024 um 01:50 schrieb Jon Anhold via wsjt-devel: 231900 16 0.4 909 ~ BG2AUE -25 Aruba 232530 5 0.4 909 ~ JR3UIC RR73; JA7WND +06 DPR of Korea Maybe some logic that checks "am I *really* North Korea?" would be good :) 73 de KM8V Jon ___ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel ___ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
