K1EL is now only offering one kit version, WKUSB-HV. With its rugged solid state relay outputs, this device can key virtually any transceiver or transmitter, even those with grid block keying. The kit includes enclosure, pushbuttons, PC board, and all parts including a USB cable. There is one surface mount part which is pre-soldered to the PCB. All you need to provide are keying cables from WKUSB to your transceiver. WKUSB uses standard RCA jacks for both Key and PTT outputs. Please note: WKUSB now ships with the newly updated WK V23 IC.
