About The 9 Bands Of The Receiver - Ten-Tec 1253 Assembly And Instruction Manual

About the
9 Tuning Bands
of your 1253 Receiver . . .
The following tuning ranges are typical but can vary +5% due to
manufacturing tolerances of the inductors and capacitors in the
bandswitching circuits. Notice that the bands begin to overlap
each other above 8 MHz. Rather than trying for continuous
tuning with no "gaps," our main goal was to make sure that the
most popular bands are covered easily.
Band 1: 1.760 to 1.990 MHz.
This tuning range includes the most active segment of the 160
meter amateur band, 1.8 to 1.9 MHz. This band is very active at
night during the winter, with year-round SSB regulars chatting
with their local or regional friends just before dawn. If you live
near a coast or other busy waterway, You also may hear beacon
signals for navigation.
Band 2: 3.3 to 4.150 MHz.
This range provides full coverage of the always-popular 80 and
75 meter amateur radio bands, 3.5 to 4.0 MHz. Traditionally,
the 3.5 to 3.75 MHz half (CW, RTTY, packet, etc.) is called 80
meters, while the 3.75 to 4.0 MHz SSB voice section is called 75
meters. Like 160 meters, this band is most active between
sundown and dawn, but it is busy year-round.
Band 3: 5.5 to 6.9 MHz.
The main purpose of this tuning range is to give you lots of
strong shortwave broadcasts in late afternoon through early
morning on the 49 meter band, 5.95 to 6.2 MHz. Many other
transmissions also can be heard in this tuning range.
Band 4: 6.8 to 8.5 MHz.
The popular 40 meter amateur band is 7.0 to 7.3 MHz, with
many evening AM broadcasts among the ham CW and SSB
signals. Look for station CHU, the Canadian national time signal
at 7.335 MHz. Unlicensed "pirate" broadcasters can sometimes
be spotted around 7.4 MHz.
Band 5: 8.5 to 11 MHz.
This band lets you tune all of the popular 31 meter broadcast
band, 9.5 to 9.9 MHz. You can also find the WWV time signal
at 10.0 MHz (or on Bands 7 and 8 at 15.0 MHz.) The 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.
