Band Coverage: 1.8 - 2.0, 3.2 - 4.7, 6.5 - 8.5, 13.4 - 19.6, 17.6 - 23.0
MHz, With 10 meter modification, 17.6 - 26.5, 20.6 - 31
MHz.
Drive Power: 65 to 80 watts typical for 1500 watts output.
Efficiency: 50 - 65%, depending on frequency, drive level, and load.
Distortion: -35 dB from 1 KW RF output level.
Harmonics: -50 dB typical.
Input/Output Impedances: 50 Ohms.
CW Break-in: QSK with vacuum relay. RF sensing circuit prevents keying or un-keying if 10 mW of RF present on the RF drive line. Switching time less than 8 ms.
Tube Complement: Two Eimac 3CX800A7 ceramic, external anode triodes in a grounded grid circuit. Plate dissipation, 1600 watts.
Plate Voltage: HI = 2400 Vdc, LO = 1800 Vdc, no load.
Cooling: Ducted forced air, vertical exhaust, using a two speed centrifugal blower.
Metering: Full time plate current. Switch selected plate voltage, grid current, forward power or reflected power. Peak power is indicated on a 10 element LED bargraph display. The first nine elements are amber - the tenth LED is red and indicates 1500 watts output.
ALC: Negative-going, adjustable threshold.
LED Status Indicators: Overdrive, Standby, Wait, Operate..
Primary Power: 220 - 250 VAC @ 20 A, maximum. 117 Vac operation possible but not recommended.
Protection: Primary line fuses, plate current fuse, ac line and high voltage interlocks.
Front Panel Controls: Power ON-OFF; Mode (Standby-Operate); plate voltage select (HI-LO); Plate TUNE; Loading; BAND Switch; METER Switch.
