7. SPECIFICATIONS
7.1. Parameters
a) Frequency Coverage

NOTICE
In continuous carrier modes (RTTY etc.) for transmissions longer than 15 minutes (up to
several hours depending on ambient temperature), the external auxiliary fan must be
mounted.

• 50-54 MHz - better than 66 dB below rated output;
f) Input and Output Impedances
• Nominal value: 50 Ohm unbalanced, UHF (SO-239A) type connectors;
• Input circuit: broadband, SWR less than 1.3:1, 1.8-54 MHz continuously (no tunings, no
switching);
• Bypass path SWR less than 1.1:1, 1.8-54 MHz continuously;
• Output (antenna) impedance matching capability: SWR up to 3:1 or higher;
g) RF Gain
• 12.5 dB typically, frequency response less than 1 dB (50-60 W drive power for rated
output);
h) Mains Power Supply Voltage
• 85-132 VAC / 170-264 VAC (100, 110, 120, 200, 210, 220, 230 & 240 V nominal taps,
