[PPRAANet] Do you even Quansheng bro?

[Joshua]

Update: I've gotten a request for the bricked UV-K5.

> I got around to ordering a UV-K5, 5R, and K6 running the egzumer firmware on github this month. They are fun to try with the new firmware. Much faster scanning, more menu options, S meter, able to show both channel name and frequency, and copy a frequency of a channel to VFO mode (haven't tried that one yet). The original FW is slow, a lot like an older Baofeng (haven't tried any newer ones). NOAA is disabled by default, and the hotkey is reused for the spectrum analyzer access. Copying my FT-70's channels via CHIRP worked well. Just the caveat that the UVs only have 2 lists, and no memories. So I only transferred the CO based memories over and manually added to either list 1 or 2. The official Baofeng programming cable works with them, and the online Flasher tool is pretty helpful. I tried with the manual flash tool and bricked the UV-K5. Oops. Will have to look at the mod to recover them eventually. Unless someone else wants to try, then you can just have the radio and charge doc. The UV-K6 does have a HW issue where it is missing a capacitor to the connector and is unable to transmit over the Kenwood audio connector if the squelch is open. Doesn't really impact me. But I like the orange screen. The missing USB C on the 5R is probably a deal breaker, and it will be a backup radio. Looks like the receiver is an open barn door. That's helpful for remote hiking and camping, but could be awful in parts of town. Haven't had an obvious problem in the house. But in a more modern vehicle, I heard some memories open the squelch (couple of SkyHub ones, but those had issues on my FT-70, too). Digging through the code on github was fun. If you've worked with programming CPUs of different instruction set complexity, you can tell this is a simpler one. The devs have to resort to tons of globals to avoid generating a dozen load immediately/load offset pairs to access complex structures. Very shallow function callstacks, too, so the instructions burned on stack management are minimized. Code size and task performance is a balancing act on these microcontrollers.

Here's a fantastic vid with side by side firmware comparison. If you don't know, these radios have quite the "modding community" going on. Lots of boundaries are being pushed & it's quite interesting! https://youtu.be/h3kRejcPboo?si=vbRGIRj_PoulFLCI 73, Derek / KØATV Get Outlook for Android ______________________________________________________________ PPRAANet mailing list Home: http://mailman.qth.net/mailman/listinfo/ppraanet Help: http://mailman.qth.net/mmfaq.htm Post: mailto:PPRAANet at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ PPRAANet mailing list Home: http://mailman.qth.net/mailman/listinfo/ppraanet Help: http://mailman.qth.net/mmfaq.htm Post: mailto:PPRAANet at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
