Radio Shack DX-394 - Specialized Frequency Bands; Aircraft and Maritime Communications; Time Standard and Long Wave Bands

Aircraft Frequencies
Most transmissions are in SSB, although
you
car
stil
hear
some
AM
transmissions.
Aircraft on international routes sometimes
use SW. Here are some ranges where
you might hear aircraft communications.
Note: Try to receive primarily in the USB
mode, but you can try LSB and AM, alsa.
4,650-4,750 MHz
6.545-6.765 MHz
8.815-9.040 MHz
10.000 10.100 MHz
11.175-11.400 MHz
13.200-13.360 MHz
15.010-15.100 MHz
180018,030 MHZ
Ships and Coastal Stations
Most transmissions from ships and
coastal stations are in USB and CW. You
сап hear these transmissions in the fol
lowing bands.
Note: Try to receive primarily in the USB
modo, but уси can try LSB and AM, азо.
2,000-20 MHz*
4.063-4.139 MHz
4.361-4.438 MHz
8.195-8.181 MHz
12.330-12.420 MHz
13:107-13 200 MHZ
16.460-16.565 MHz
* The Coast Guard and small toats use
this band, with 2.182 MHz sot asido as tho.
International
distress
and
emergency
channel.
Time Standard Frequencies
The following frequencies announce the
exact me of day at specified intervals,
WV in Fort Collins, Colorado:
2.500 MHz
5.000 MHz
10.000 MHz
15.000 MHz
20.000 MHz
CHU in Canada: 71325 MHz
VNG in Australia: 4.500 and 12.000 MHz
Long Wave Band
‘The 150-509.9 kHz range is known as the
long wave band. Moet stations 1 this
range serve as beacons for aircralt and
marino navigation by continuously trans-
mitîng their call leters. Through your
local library, you can find books on air and
marino navigation, which contain lists of
the beacon stations and their locations.
Reception for this range ie best betwoen
6:00 PM ard midnight (your time)
Some ships also use thi range, with 500
kHz set aside as an international distress
ard emergency station,
Most stations in this range use CW
(Morse
coda),
although
scmo
usa
AM
voce transmission for weather brcad-
cass.
