Radio Model, Control
Head, and Version
Identification
Model charts for the different versions are found in the basic service
manual. “Versions” are identified by the model number “suffix.” Although
the charts are very similar, there are subtle but very important differences.
Determine from the radio's identification label, which model control head
and version is yours. Keep this information handy for future references.
Determine the model and version of the radio as follows:
SPECTRA
Typical model number – D
4 3 K M A 7 K A 7 A K
If your model number begins with a “D,” your radio is dash mounted; if it
begins with a “T,” it is a remote unit. In the above example the “4” refers to
the radio power; “8” is high,“4” is mid, and “3” is low power. The “A7” refers
to the control head model number, and the letter “A” refers to the version.
ASTRO SPECTRA
Typical model number – T
0 4 S L F 9 K W 7 A N
If your model number begins with a “D,” your radio is dash mounted; if it
begins with a “T,” it is trunk mounted. In the above example the “L” refers
to the radio power (“A” is low power, “L” is high), and varies between “A”
to “L”). The “A7” refers to the control head model number, and the letter
“A” refers to the version.
