✔ Selectable 1W or 5W drive
At last, the number one requested new product is here! The
PA100 is a professional quality FM power amplifier with 30-40
watts output that has variable drive capabilities. With a mere one
watt drive you can boost your output up to 30 watts! And this is
continuously variable throughout the full range! If you are currently using an FM
transmitter that provides more than one watt RF output, no problem! The drive input is selectable for
one or five watts to achieve the full rated output! Features a multifunction LED display to show you output
power, input drive, VSWR, temperature, and fault conditions. The built-in microprocessor provides AUTOMATIC
protection for VSWR, over-drive, and over-temperature. The built-in fan provides a cool 24/7 continuous duty
cycle to keep your station on the air!

past with PLL control making your signal rock solid all the time - just like
commercial stations. Kit comes complete with case set, whip antenna, 120 VAC power adapter, 1/8" Stereo to
RCA patch cable, and easy assembly instructions - you'll be on the air in just an evening!
