GENERAL INFORMATION
VOR MODE
9.96 kHz sub-carrier
Range:
0 to 49.9% depth in 0.1% steps.
Modulation:
Frequency modulated by a 30 Hz tone with 240, 300, 360, 420,
450, 480, 510 and 540 Hz deviation.
30 Hz tone
Range:
0 to 49.9% depth in 0.1% steps.
Arithmetic sum of 30 Hz tone and sub-carrier AM depth are
limited to 99.8%.
Selection:
By keyboard entry of depth and variable by

keys and rotary
control.
Bearing control: Relative phase of 30 Hz tone and sub-carrier modulation
adjustable from 0° to 359.9° in 0.1° steps by entering VOR
bearing. Bearing can be entered as TO or FROM the beacon.
Bearing
accuracy
±0.05°.
Additional
modulation:
Available on 0° bearing from an internal or external modulation
source.
AM depth accuracy:
±3% of setting ±0.5% for carrier frequencies up to 400 MHz.
Frequency:
The VOR repetition frequency of 30 Hz may be varied in 0.1 Hz
steps. The sub-carrier frequency and deviation maintain a fixed
relationship with the VOR repetition rate
Frequency accuracy:
As frequency standard.
Audio output:
Available from the LF OUTPUT socket.
ADF MODE:
Provides default modulation of 30% AM depth on a 190 kHz
carrier at 1 kHz modulation rate. AM depth, carrier frequency
and modulation frequency can be changed from the default
values.
SEL-CAL MODE
Provides amplitude modulation with SEL-CAL (SELective
CALling) tones.
Data entry
By soft keys labeled A to S, of up to 2 pairs of characters.
Timing:
Default 1 s tone duration, 250 ms tone gap. Tone gap, duration
and start delay can be changed from the default values.
