- Bypass path: VSWR less than 1.1:1, 1.8-30 MHz continuously, 200 W maximum;

- Output (antenna) impedance matching capability: VSWR up to 3:1 or higher.

g) RF Gain: 11dB typically, frequency response less than 1dB (50 to 70 W drive power for rated

output).

h) Primary Power: 85-132 V/170-264 V ac (100, 110, 120, 200, 210, 220, 230 & 240 V nominal taps),

+10% -15% tol.), 50-60 Hz, single phase, 1200 VA.

i) Complies with CE safety and electromagnetic compatibility requirements as well as FCC-regulations

(10 & 12 m band locks provided).

j) Operating size & weight, incl. feets, excl. knobs and connectors (see also S.2-3 Amplifier Location

Selection): WxDxH: 407x315x169mm, 18kg (16x12.4x6.65 inches, 39.7Lbs).

k) Operating environments:

- Temperature range: 0 to +50 degrees Celsius;

- Humidity: up to 95% @ +35 degrees Celsius.

- Height: up to 3000 m above sea level without output deterioration.

6-2. Functions

a) Antenna Impedance Matching Process: aided by a plate-load True Resistance Indicator (TRI).

b) Two antenna outputs selectable by a button on the front panel.

c) Protections:

- Cover interlock for operator's safety;

- Inrush power-on current limited to the nominal consumption;

- Control grids, screen grids, and plates currents;

- T/R sequencing - 10ms minimum hold off delay required between transmit request and RF

appearance;

- Antenna relay contacts, including RF power induced in antenna from another nearby transmitter;

- Antenna matching quality;

- Reflected power.

d) LED bar-graphs for forward peak power and reflected power.

e) Service visualization of grid 1 DC currents, grids 2 DC voltage, and plates DC currents.

f) Tubes: two 4CX250B (7203) ceramic-metal tetrodes with a total plate dissipation of 500W (forced

air cooling), grid-driven.
