The KHP hand portables, newly redesigned from the precedent series deliver exceptional value. The radio contains highly integrated PCBs, mounted on a rigid aluminum die-cast inner chassis. This fully CPU controlled intelligent radio is smart enough to fulfill diversified needs from market today. All those features at an excellent cost scheme.

Ergonomics design
Comfortable grip and hold, Large control knobs, tn-color LED indicator, bright LCD backlight, amiable beep tones. Slightly slant PTT apron design. Finger rest on a side sets your palm comfortable around the radio and secured grip and drop prevention. Our scope to professional design.

Your System Integration
The TRX part and the Logic part are segregated by design which will enhance your own logic designs and local contents. The TRX board provides the ready I/O ports for various interfaces including one for FFSK modems for trunking logic or other custom applications of your own. The radios without our original Logic board are available in all bands.
