Brand new! ... specially designed for CW work ... specially for novices ... the Heathkit HX-11

Here is an excellent CW transmitter for the novice or general class amateur who appreciates a clean, quality signal and wants the most quot;watts-per-dollar" in an amateur transmitter. The new HX-11 is designed exclusively for CW work on the 80, 40, 20, 15 and 10 meter amateur bands, using either crystals or external VFO. The efficient circuitry features a single 6DQ6A final amplifier stage with full 50-watt plate power input and a 6CL6 crystal oscillator. The husky power supply uses a heavy-duty 5U4GB rectifier and top-quality "potted" transformer for long service life. Other features include single-knob bandswitching, switched antenna relay power, pi-network output coupling, built-in low-pass filter for minimum TVI, and easy-to-read panel meter for final grid or plate current indication. Easy access to crystal socket is provided by a metal pull-out plug on the side of the cabinet. Very easy to build and operate with the complete instructions supplied.
