Overview Of Tuning Settings; Evaluation Of The Resource Used; Backing Up The Non-Volatile Memory; Cable Required From The Radio Station - Acom Owner's Manual

8.2.6. Overview of Tuning Settings

Method for overview of all tuning settings is provided. Also, provided is method for deletion of individual or
all tuning settings.

8.2.7. Evaluation of the Resource Used

Provided is a method for evaluation of resource of inductors and capacitors used for each stored user tuning.

8.2.8. Backing Up the NON-Volatile Memory

Method for backing up to a file, and restoring from a file the contents of the non-volatile memory of the
tuner using a computer connected through the amplifier RS-232 port (using the ACOM TERMINAL S program,
freely distributed).

8.2.9. Cable Required from the Radio Station

A single cable is required from the radio station to the tuner. Along with the RF power, the coaxial cable from
the ACOM amplifier to the tuner combines also the DC power supply of +26 VDC and the 60 kHz FSK data for
bidirectional control. Note the type and maximum cable length (see Section
).
Input Coaxial Cable

8.2.10. Protection Mechanisms

From too high or too low power supply voltage (22 to 30 VDC);
•
From power supply voltage with reverse polarity;
•
From excessive RF voltage at the antenna output (above 500 Vrms);
•
From excessive RF current at the antenna output (above 10 Arms);
•
From excessive reflected power at the antenna output (above 400 W);
•
From excessive forward power at the antenna output (above 1600 W);
•
From excessive input power during tuning (above 60 W);
•
From relay switching under RF power (hot switching);
•
From extreme air temperatures within the internal volume of the tuner
•
(-40...+65 °C / -40...+150 °F);
From accumulation of atmospheric electricity and lightning strike close to the antenna - by a
•
leakage resistor and lightning arrestor in the circuit of the operating antenna and direct
grounding of the unused antennas;
When the power supply is turned off, all antennas are automatically grounded.
