I paid less than $16 USD and mine came with a US adapter, a dock with a slot for just the battery and a slot for the whole radio (only charge one at a time though), and a earphone mic with PTT surveillance kit. I bought these under the WLN brand and the Zastone brand and model X6, both in black. (They are also available in white also). One unit has low mic audio from the internal mic, but external mic is good, so it's a mic problem, probably need replacing. I haven't done that yet. My friends really like it also. Great for the kids, one of them said. There is a hack to program it on VHF, but I won't TX on it. Just for RX but the antennas isn't resonant on VHF. So not very sensitive there.

wow i never expected to find something when typing in "wln kd-c1 disassembly" but seems like youtube has everything. thanks! (i'm wondering how can i put a battery in this thing that lasts longer than the stock 16 hours standby)

[@dayohadayhart]

Could you please take out the internal antenna and check on what frequency it is matched?

[@dayohadayhart]

Can we replace the mini USB port with TYPE-C?

[@boggs2005]

Will it work on FRS Frequencies?

[@caloocandrrmo1710]

do you have software for kd c90u

[@AECRADIO1]

FCC is not law, only rules. Too many wrongly exchange the info. Any software to program it, or is it preprogrammed? DIP switch programming? Multi button hold/press to step through channels?

[@IMSAIGuy]

you can program it via USB cable. not chirp but they have a different program. hold press bottom button to start scan.

[@paulcohen1555]

We need some measurements, power out, spurious, receiver sensitivity.

[@maka5955]

@@IMSAIGuy Chirp works. It's have WLN KD-C1. Only Plus version with channel display need own program.

[@dayohadayhart]

There are two version of this in my country. One can be detected and programmed with chirp, another can't.

[@e75channel]

Interesting video.

[@bobkozlarekwa2sqq59]

I’m curious about power output and what frequencies were really programmed into this

[@riccardopapi5992]

Very likely PMR channels: 1 446.00625 2 446.01875 3 446.03125 4 446.04375 5 446.05625 6 446.06875 7 446.08125 8 446.09375 9 446.10625 10 446.11875 11 446.13125 12 446.14375 13 446.15625 14 446.16875 15 446.18125 16 446.19375

[@bobkozlarekwa2sqq59]

If they are on 446, that’s in the amateur radio band. Definitely needs to be reported to the FCC

[@AECRADIO1]

Impossible to get 5 Watts with 1.0A current. USB is common interface for data/charging these units. HYT has this, as do most.

[@AECRADIO1]

Screw holds antenna and chassis to front case.

[@AECRADIO1]

Volume control probably has a collar nut.

[@AECRADIO1]

Even cheaper...soldered antenna. Easy to retrofit an SMA.

[@brandonbarr2784]

Google the frequency it’s much faster than making a video

[@mjrtude]

Hey don't leave us hanging. Program it up lets make some measurements.

Looks a little like an HYT clone.
