REVISION HISTORY

1.0 – Initial release

1.1 – Added section Step 9 in Section 4

Page:7 print date: 2/14/06

150GTL Channel Display

The 150GTL has 4 bands which cover frequencies from 28.000 to 29.700 MHz in 5KHz steps.
The dual seven-segment channel display indicates the operating frequency.

BAND FREQUENCY RANGE CHANNEL DISPLAY RANGE

A 28.000 to 28.495 00 to 49.
B 28.500 to 28.995 50 to 99.
C 29.000 to 29.495 0.0 to 4.9.
D 29.500 to 29.700 5.0 to 7.0

You must be careful to note the decimal points!

This decimal point
shows the MHz band.

OFF = 28.xxx MHz
ON = 29.xxx MHz

These two digits are
determined by the status
of the decimal between
the channel numbers.

Decimal OFF = 28
Decimal ON = 29

This decimal point
shows the last digit.

OFF = xx.xx0 MHz
ON = xx.xx5 MHz

x x . x x x MHz

These two digits are
taken directly from the
channel display.

The last digit is determined
by the status of the far-right
decimal point.

Decimal OFF = 0
Decimal ON = 5
