My musings on Ham Radio … and stuff!
F5IGF was up and down with QSB, but look at the screen capture … he was right at -24, the lower limit of decoding in WSJT-X. His preceding transmission was at -23dB. This is using version 2.0 rc5. I seem to be completing more of these marginal QSOs with this latest version. Thanks, development team!

Checked out FT8 last night … started by using WSJT-X 2.0 rc5 … crickets! Where’d everybody go after the contest? Lots of activity on the spectrum display. So I reverted to ver 1.9.1 and voila! … tons of stations!
I think it’s going to be an uphill battle to move everybody to the newer version. Still, when the non-beta version 2.0 is released on December 10th, I may be surprised. I hope so … this newer iteration of WSJT-X really has some good features and Joe and his crew seem to have fine-tuned the decoding algorithm for optimum performance.

I got on for a while late yesterday afternoon, using WSJT-X 2.0 rc5, and had some luck. It wasn’t a lot of luck … just some luck.
You can see, there is more 77-bit messaging showing up on the bands, but it’s still pretty slim pickings. I’m hoping the BIG flip-over will come when version 2 is finally released in its finished form on the 10th of December.
Eighty meters propagation was really good last night. the low bands are the place to be to work stations, but there are still some real gems to be found on the higher frequency bands. I even heard some strong CW signals up on ten meters yesterday evening.
Oh, I got a confirmation from 5T2AI, Ahmed in Mauritania, yesterday. Worked him last week. This LOTW stuff works fine (and fast)! Shame on you if you’re still a denier :-)!!

I was just fiddling with numbers this afternoon and was surprised to find that my LOTW account shows a 68.42% confirmation rate. That’s a pretty good number, isn’t it? Had to recheck my cipherin’. I had no idea it was that good. If only the lottery had that kind of return, I could put up that 75-foot tower with multiple beams on it!!
A lot of those confirmations are due to digital modes. Lots of digital operators are uploading to LOTW in near real-time, as the QSO is ending, or very soon after. Logging programs make it so easy nowadays. The software does it for you.
I see WSJT-X 2.0 rc5 is now available. Joe says that it is pretty much what the final release on December 10th will look like. I haven’t had a LOT of luck working stations using the new 77-bit message format. Lots of people still hanging on to the older 75-bit messaging. Hopefully, they’ll move to the new format, but I expect it’ll take a while. Hams can be slow to change …
One incentive is the contesting mode that’s built-in and the ARRL RTTY Roundup on the radar in January. This’ll be the first time FT-8 has been a contest mode, and I’m looking forward to the challenge.

I was right about the Win4Icom/N1MM+/WinKeyer USB problem … it was a port conflict. I had Win4Icom and N1MM+ both pointing to the same serial port for the WinKeyer. The simplest solution was to temporarily disconnect the connection from Win4Icom to the WinKeyer, and now N1MM+ works fine. If I’m not using N1MM+, I can just toggle the port back on in Win4Icom and all is well again … easy peasy!
I rushed home from choir practice and caught the last half of the Tidewater VA DMR Net (TG31515). It was a small group tonight and Darrell, KF4HJW was doing the honors as Net Control. Don’t know where Howard was … hopefully he’ll be back next week.
I downloaded the latest version of JS8Call this evening … JS8Call v0.7.5-devel. The main update is a fix for some decode issues, and there are several other fixes as well. Jordan, KN4CRD, is really responsive to feedback and the groups.io site is a good way to provide that interaction.
