General information

Carrying case and transceiver together form a portable VHF station. The easily-portable VHF station can be used, for example, for mobile and fixed operations on airfields or landing strips. It an also be used in hot air balloons, for ferrying aircraft or or recovery of gliders.

The carrying case contains the battery, speaker, antenna socket, the way diode connecting socket for the microphone or microphone speaker and the voltage converter. A microphone/speaker, a headset or a helmet (ultralight) can be connected to the 5-way diode socket. The built-in battery is a maintenance-free rechargeable 12 V / 2.2 Ah dry lead battery.

The battery can be charged via the external d.c. socket. The charging voltage can be varied between 10 V and 32 V. The charging time for a heavily discharged battery is approximately 8 hours. The nominal operating time for the portable VHF station is approximately 6 hours at a keying ratio of 1:10 normal radio traffic) and transmitter output power of 5 W. Reception is then still guaranteed for a further 2 hours.

The portable VHF station contains a monitoring stage for the battery voltage which is activated when the unit is switched on. If the battery voltage drops to between 11 V and 10.5 V the indicator begins to flash.

The portable VHF station is ready for operation after the antenna is screwed in place and microphone speaker plugged in.

When the ILL button is pressed, the panel lighting in the AR 4201 - ( ) comes on for approximately 10 to 20 seconds.
