[Motorola] What do i have?

[Glen Zook]

Look at the part number for the receiver "front end". 
It should start out with the letters TLB (the "B"
indicates "low band").  Then, there will be 4 numbers
and a final letter.  The final letter will indicate
the actual "sub" band range.  This is as follows:

A = 25 - 28 MHz
B = 30 - 36 MHz
C = 36 - 42 MHz
D = 42 - 50 MHz

Also, the exciter and the final amplifier assembly
should have a similar type of part number.

This same thing holds true for most Motorola equipment
manufactured between 1955 and at least 1980.  Highband
and UHF also have various letters that indicate the
sub range.  
The "P" transmitter has a 8560A type tube in the
final.  This is a conduction cooled tube.  The "LHB"
type of equipment, which is more common, has the 8643
type of tube in a few of the very latest versions and
the 5894 in most versions.
