The Model C-6500 is a synthesized, general-coverage, communications receiver; a new "Standard" with high-quality, low-cost performance that will please the most critical listener. Reception capability is provided for a-m, CW, and SSB.
Unusual stability is achieved by using a synthesized, drift-cancelling injection system in 30 tunable ranges, covering the entire broadcast band starting at 500 kHz through 30 MHz. A 10-MHz reference oscillator provides the frequency stability necessary for excellent SSB reception.
Dial accuracy is better than 5 kHz, which is sufficient to locate and identify stations on known frequencies.
There are two separate detectors, product and diode, to provide excellent performance for both SSB and AM signals. A mode switch provides wide or narrow selectivity. A tunable preselector allows the user to adjust for maximum sensitivity and interference rejection.
Completely solid state in design, the Standard C-6500 operates from AC mains as well as eight internal type "D" flashlight cells. Automatic switchover to battery operation is accomplished if the AC power should fail.
