Inside the Quansheng UV-K5 stock antenna.
Was given an extra, so I pulled it open to see how this particular one was made.
Interesting to see a PCB instead of just a cap.
And it as space for two SMD caps.

New #Quansheng announced.
10m/6m/2m/70cm Quadband with 0.5 - 1160MHz wide receive. AMF/FM/SSB receive and likely only FM TX, like usual.
Also 6m/2m/70cm tribander with the same wide RX.
Sadly no #23cm even on receive.
Will be interesting to see what price point these end up on.

UV-K5 came in the mail yeeaaaaaaaaahhh!!
Had a nice time in the CQ VHF contest. Lots of 2m CW activity thanks to the popularity of the Quansheng UV-K5. No 6m openings though

#uvk6 #uvk5 mods for #hamradio digital modes -- both hardware and firmware -- are now documented here: https://github.com/mobilinkd/uv-k6-digital-mod/blob/master/UV-K6.ipynb
Für das Quansheng UV-K5 gibt es inzwischen eine ganze Reihe modifizierter Firmwareversionen. Einige sind irgendwie eingeschlafen, andere aus dem Netz verschwunden.
Die Mod von Egzumer scheint aktuell die Beste mit hinreichend intuitiver Bedienung, einem großem Funktionsumfang und mit Spektrumanalysator zu sein. Die aktuelle Version ist die v0.22 und lässt sich auch bequem über den Browser flashen.

Die Beschreibung ist umfangreich und es gibt auch ein Hidden Menu

Completely reverse engineered datapacket for Quansheng UV-K5 radio.
Not just schematics, but a complete kicad project, so that one can properly document modifications and make derivates.

Sachen gibts. Ein 34€ Handfunkgerät, welches für 2m und 70cm ausgelegt ist, lässt sich durch das Aufspielen alternativer Software sogar als Kurzwellenempfänger verwenden. #uvk5 #hamradio #Quansheng #Chinaböller #basteln #technik
Made a Sinitsa style CW adapter for the #Quansheng #UVK5 handheld radio.
To see if it would actually work.

Some #BK4819 news!
A programming application note for it was shared in the English language Quansheng UV-K5 Telegram group.
So I machine translated and mirrored it.
Here is a direct link to the machine translated one:

And here is the original Chinese language one to reference.

Receive LO leakage from a #Quansheng #UVK5 set to dual watch.
As the clocks are divided down to get the exact LO, the two leaking tones are quite close to each other. Unlike 1200MHz and 145.000MHz.

Test setup for measuring the RF output direct from the #BK4819 chip used in the #Quansheng #UVK5 radio.
It is soldered to the transmit output pin via the stock DC blocking cap, suspected to be 100pF.
Picked up a $30.00 Anysecu UV-K5 it arrived from China a whole 5 or 6 days ahead of time.....
And it's both better, and worse then I thought it would be.
With some interesting features, like NOAA channels, and airband - And only a few dollars more then a UV-5R - this could be the new beginner radio to give to new hams. #baofeng #UV5R #UVK5 #Anysecu #hamradio #ham #radio
