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.
