This is an interesting radio that can be found very cheap on ebay or amazon. It’s a 16 channel, 400-520 MHZ radio and charges with a USB port on the side of the radio.
It’s programmed over the headphone/mic jack with a “baofang” type cable and does come reprogramming with 16 test channels. I used chirp with the radio, WLN is listed (the radios logo may say nlw it is just backward) but you can use the factory software at Download
Overall the radio is not as bad as you would expect for $15 audio is clean, and the microphone is better than the Baofang 888s and lacks any part 90, 95 or 97. The range also is a factor in this radio, the smaller antenna makes the radio suffer in range, If you’re close to a repeater however this radio should work fine. it does support shift on transmit along with DPL and PL tones.
An interesting note with the factory software is the file at C:\Program Files (x86)\KD-C1\config.ini
This seems to define the high and low programmable frequency a HackADay.io tare-down shows the radio has some of the hardware to do 134MHz-174MHz, 200MHz-260MHz, and 400MHz-520MHz its unlikely to transmit there, but it may pick up a signal that is strong.
