Obcas se nekdo zepta, a kam se vlastne dovolate? Snazim se vysvetlit, ze otazka nezni kam, ale kolikrat signal obehne zemekouli. Kdyz jsem s tim naposledy experimentoval, maximum bylo tri detekovatelne oblety - dva jasne slysitelne. hra.remoteqth.com/chirp/2011…

Fieldwatch user, I built Fieldwatch for my own use and eventually decided it was good enough to share with the community. I enjoy the work. I make no money from it, and it's completely free, whether you use it as is or build your own work on it. That's why it's MIT licensed. There's now an app on the Play Store called "Fieldwatch: Hidden Camera Scan." It isn't mine. It's built from my code and sells weekly and monthly subscriptions. I don't know whether its paid features add anything beyond what free Fieldwatch already does. They may. I'm not against people charging for derivative work. I'd just hope it adds real value beyond what I already offer for free. The bigger issue is the name. Fieldwatch™ is trademark pending, and in my opinion, putting that name on a derivative app confuses users into thinking it's mine. I've already seen at least one person assume Fieldwatch is a paid app. In my opinion, it's benefiting from the reputation of my work. I'll be straight with you: seeing that takes a lot of the energy out of wanting to keep going. If you've used and enjoyed Fieldwatch, please help spread the word. The only official source is GitHub: [github.com/OffGridPete/Field…] Other apps using the Fieldwatch name for the same kind of app are not mine.

WSPR side-by-side test on 80m: enlarged LZ1AQ RX loop vs. a 1/4λ TX vertical. The loop decoded more stations with better SNR. The 3D-printed parts are on Printables: printables.com/model/1477767…

Multi-band CW/RTTY Skimmer for Linux? Yes! 📡 Up to 8 bands at once from a single Red Pitaya, with a web interface and a telnet feed for your logger or for uploading to RBN. More in the thread 🧵👇

The new version has not yet been fully tested, but I am releasing an AppImage (for Linux x86_64) now – primarily due to the upcoming CQ WW DX CW contest (November 28–29). cqww.com/

DIY 4-band matching unit for the vertical, with 3D-printed coils and a 3D-printed capacitor, officially went into active service today ;)

Went to bed, woke up and WIFILT speaks WSPR now :) Great for comparing antennas side by side, and everything still fits on a humble ESP32.

WIFILT learned a new trick overnight — syncing ham radio logbook to GitHub — including web search. ok1hra.github.io/OK1HRA-QSO-…

For a while now, I’ve been rating contests by the innovations they produce — and, more recently, by the number of tokens they consume ;) CQWW RTTY was a pretty good contest

Sharpening the scythe for this weekend’s CQ WW RTTY claude.ai/artifact/BqRy21Dta… WIFILT now has two different web RTTY decoders running side by side. Let’s see which one comes out on top in the heat of the contest! And yes — it’s all running on an ESP32 ;)
WIFILT now has PC binaries and can decode RTTY. Check out the image to see AFC in action.

WIFILT just learned a new trick — it can act as a JS8Call-to-APRS iGate. And yes, it works across half the planet ;) Alaska → EU
