25 AND 8.33 kHz CHANNEL SPACING
The TDAM-1000 is capable of both 25 and 8.33 kHz channel spacing. Selecting the desired
channel spacing is achieved during the frequency entry procedure. The TDAM-1000 uses the
ICAO standard where 5, 10 or 15 kHz is added to the 25 kHz channel frequencies to represent
the additional 8.33 kHz channel steps:
