Radio Navigation Equipment - Signalspaning.se

Radio Compass AN/ARN-6 is an automatic radio
compass which will provide either aural reception of modulated
radio signals in the frequency range of 100-1750
kilocycles, aural-null directional indications of the arrival
of signals using a loop antenna, or automatic loop orientation
and loop azimuth indication in degrees.
In addition to the four band frequency coverage
from 100 to 1750 kilocycles, a 2800 to 5900 kilocycle high
frequency band has been added for emergency communication
use. The setwill notfunction as an automatic compass
on this band.
Two loops are being developed: Loop AS-141/
ARN-6 having the electrical characteristics of the LP-21
and Loop AS-140/ARN-6 having the characteristics equal
to a 12 inch air core loop. Bothloops contain an iron core
type of loop in order to decrease overall size. These loops
have the best possible anti-precipitation static characteristic
and are of the blister type to reduce drag to a minimum.
The smaller Loop AS-141/ARN-6 is to be used on
fighters and the larger Loop AS-140/ARN-6 is to be used
on bomber and cargo planes.
The equipment operates from a 24 volt d.c. power
source.
Test equipment for maintenance will consist of
a test set incorporating I-100 and a special adaptor.
Army Supply Program requirements as of 8 February
1945 were 2,000 equipments for the calendar year
1945.
