Introduction
The
Bandmaster III
universal band decoder is a highly integrated unit that not only decodes band
information using
YAESU
“band data” (
note 1
), but can sense band information for all bands from
160M through 6M, including 160M, separate 80M and 75M, 60M, WARC bands and 6M by
monitoring
CAT
(
note 2
) data going to and from the radio. The
Bandmaster
III
also contains all
circuitry for level conversion thus eliminating the need for a separate
CAT
radio interface (
note 3
).
It supports radios from
ICOM
,
KENWOOD
,
YAESU
as well as other radios like the Elecraft
K3
or
TENTEC
ORION
using CAT protocols from these manufacturers (
note 4
). You can even use the
decoder as a stand-alone unit where it will monitor the
CAT
commands,
YAESU
“band data” (
note
1
) or
ICOM CI-V
data from the radio and automatically switch to the band being used at that time
by the radio and this without any computers attached to the
Bandmaster III
or the radio! Or it
can be connected to your computer and used with your favorite logging or radio control program
as your CAT interface or level converter, thus replacing your existing converter (
note 3
) and
antenna selector.
Using the
Bandmaster
III
software you will also have the ability to configure the radio interface
and set the frequency limits for each band, thus providing even a great deal more flexibility. The
Bandmaster
III
gives you two separate relay contact outputs for each band. One set of contacts
(The B contacts) switch to ground when activated and the other set (A) is switched to a
"Common" pin(13). This "Common" pin may be connected to ground or any voltage source you
desire.
Note 1:
YAESU
BCD Band Data information does not support 75M and 60M.
Note 2:
CAT
=
C
omputer
A
ided
T
ransceiver, CAT is used to control your radio via computer based software, these are
often stand alone software or can be integrated into logging software and/or satellite control software.
Note 3:
ICOM
CT-17 or
YAESU
FIF-232 or the
KENWOOD
IF10a/IF-232C.
Note 4: The
K2
uses
KENWOOD
protocol and some of the
TENTEC
emulates an
ICOM
IC-735, the K3 produces Yaesu
Band-data.
