MFJ-8100
World Band Receiver
17
30 meter ham band (CW and RTTY only in the USA) is at 10.1 to
10.15 MHz. This tuning range is generally busy 24 hours a
day.
Range D: 13.2 to 16.4 MHz.
On the 20 Meter ham band (14.0 to 14.35 MHz), you can hear
strong CW and SSB voice signals from around the world
throughout the day and well into the evening. This is the
most active and crowded of the international ham radio bands.
You also are able to tune the 21 Meter shortwave broadcast
band (13.6 to 13.8 MHz), and all of the 19 Meter band (15.1
to 15.6 MHz). Station WWV at 15.0 MHz provides precision
time and frequency information.
The 19 Meter band is very good in the morning hours of winter
and the late afternoon hours of summer.
Range E: 17.5 to 22 MHz.
This tuning range is provided to assure good listening
variety during daylight hours. It includes the 16 Meter
broadcasting band (17.55 to 17.9 MHz), the 17 Meter ham band
(18.068 to 18.168 MHz, and the 15 Meter ham band (21.0 to
21.45 MHz). Station WWV also broadcasts on 20 MHz.
SHORTWAVE LISTENING IN GENERAL
In addition to the specific "bands'' highlighted above,
you'll hear thousands of OTHER shortwave signals. Many will
be military or government Morse code transmissions, plus very
"odd'' noises of weather FAX, wire service and other data
transmissions. You can also hear government or military SSB
voice transmissions and even an occasional unlicensed
"pirate'' station.
A rule of thumb is that the lower frequency ranges (A, B, C)
are most active during the late afternoon, evening and
through the night. The higher frequencies (D and E)
generally are most active during daylight hours.

Following are minor problems which are easy to solve:
Extremely weak volume on all bands.
