Write to CTCSS TX Frequency/NRZ Baud Data Rate Register –A/C 73
H
(7B
H
) followed by 2
bytes of Command Data.
The information loaded to this register will set either the:
(a) CTCSS TX Tone Frequency
(b) NRZ TX Baud Rate
(c) NRZ RX Baud Rate
The chosen mode for this register (a, b, or c) is determined by the MX805A modes enabled by the Control
Register, as shown in Table 8.

The two words, P and Q, loaded to this register are interpreted as:
P =
a binary number to set the TX Sub-Audio Lowpass filter bandwidth (applicable to NRX and CTCSS
modes).
Q = A binary number to set the frequency r baud rate of the selected functon.
