Notice that, for frequency parameters, the 100
MHz digit must be present and set to zero for
frequencies below 100 MHz. Also notice that
decimal frequency data must be translated into
BCD (binary-coded decimal) parameters for sen-
The rightmost column of the Instruction Code
Chart indicates the number of Status Update
bytes to be expected after sending each com-
mand. The Status Update Chart and accompany-
ing tables show the format of these bytes:
notice some parameters and flags are carried
in bit fields.
The CAT jack also provides access to the PTT
(Push-To-Talk) line at pin 4 to allow keying
the transmitter. This pin has 8V DC on it
when open-circuit (during reception), and ac-
tivates the transmitter when grounded (sour-
cing 8 mA).
Also, the AGC signal at pin 5 of the CAT jack
provides a high-impedance analog sample of the
receiver AGC voltage: from 4V (with no signal)
to OV (with strong signal). This may be ap-
ding, and that the LSD (least significant plied to an A-D converter to provide a digital
digit, Parameter 4, 100's and 10's of Hz) is signal for signal strength indication and
sent first. scanning control by your computer.
