Valley Enterprises Compatible with HYT FTDI USB PC26 Radio Programming Cable TC500, TC600, TC700; Tera 500, 505, and 590; Blackbox, Blackbox Plus, and Bantam-M1

I ordered this with a Tera TR-505 radio from the same seller, it arrived packed neatly in the same box as the radio. It works, the chipset is FTDI so it should be compatible with whatever operating system you're running. The radio only has 16 preset channels (15 if you enable scanning), but that's enough for GMRS or MURS. You can't legally transmit more than 0.5w on GMRS channels 8-15 anyway so I just skipped them.
