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 grid, screen grid, and plate currents;

- T/R sequencing;

- 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 current, grid 2 DC voltage, and plate DC current.

f) Tube: a single Svetlana 4CX800A (GU74B) high-performance ceramic-metal tetrode with plate

dissipation of 800 W, grid driven, forced air-cooling.
