KXPA100 features include:

• 100 W output on 160-6 m with 5 W input typical
• 13.8 VDC powered; 20 A typical current drain
• 7 lbs with KXAT100 installed.  10 x 5.125 x 4.25"
• Compact unit ideal for both desktop and mobile use
• Solid-state diode T/R switching — fast, silent T/R and QSK
• Large convection-cooled heat sink for reliable and quiet operation
• Modern design with rugged MOSFET output stage
• Internal wide-range automatic antenna tuner (KXAT100 ATU option)
• Second antenna jack provided with KXAT100 ATU option; controlled by KX3's ANT switch
• Fast, bright LED bar graphs for power and status; KXAT100 ATU option adds SWR bar graph
• Seamless integration with the Elecraft KX3 transceiver
• Works well with any low-power transceiver, requiring only RF and PA KEY inputs
• RF-based frequency counter automatically switches bands with any rig
• Optional band-data input support the K3/10, KX3, Yaesu FT-817, Icom IC-703, and other rigs
• Dual APP power connectors for additional friction-fit if needed (mobile); optional daisy-chaining of 13.8 V to power rig
• Optional KXPACBL adapter connects KX3 to the KXPA100 with a single cable for keying, band data, and control
• KXPA100's PC port allows use of remote-control and logging applications with the KX3 without software configuration changes
• KXAT100 internal ATU option matches 10:1 SWR (5:1 typical on 160 m and 6 m); uses Elecraft's fast matching algorithm
• KXAT100 ATU settings saved per band, per band segment, and per antenna for instant recall
