208/240 volts, 1S%. 50/60 Hz. three-phase.

820E-1: 5.5 kw max. with built-in reduction to 1 kw.

820F-1: 10.6 kw max. with built-in reduction to 5 kw. Trimmer capacitors provided on the RF exciter for adjusting crystals to exact center freguency. Stability as follows:

±S Hz. 0°C to +35°C (32°F to 95°F)

±10 Hz. -10°C to +45°C (14°F to 113°F)

Oesigned for feeding standard 50-ohm coaxial transmission lines. Matching to other impedance op-tions can be supplied on special order.

Complies with or exceeds FCC regulations regarding harmonie and spurious radiation.

Eguipment incorporates high level modulation with most desirable response characteristics for broad-cast use.

150/600 ohm, balanced.
