SPECIFICATIONS:
Power Ratings:
SSB 800 Watts Nominal PEP Output on High Power
AM 500 Watts Nominal Output on High Power
AM 300 Watts Nominal Output on Low Power
Frequency Coverage:
26.0 to 30.0 MC
Tube Complement:
Four 8950’s in grounded grid and one 8950 Driver in grounded cathode.
RF Drive Requirements:
AM Operation - Nominal 3 Watts
Single Sideband - Nominal 7 Watts PEP
Meter:
Reads relative output RF voltage.
Relay Keying:
In SSB position, automatically switches the amplifier into the “Transmit” mode when SSB
modulation is present. Returns to receive mode after a short delay when no modulation
is present.
In AM position, the AM carrier of the transmitter keeps the amplifier in the
“Transmit” mode as long as the transmitter is keyed.
“PI” Output Circuit:
Matches 52 to 75 ohm load and other impedances where the SWR does not exceed 2.5:1
Pre-Amplifier:
Provides approximately 6 db gain for received signals.
Power Supply:
Computer grade electrolytic capacitors and conservatively rated silicon rectifiers together with a
heavy duty power transformer provide a reliable power source.
AC Input: 117 Volts, 50-60 Hz
