3.12.14 Concerning the programming of Frequency No. zero some considerations
are to be made; refer to paragraph 3.11.6.
If no transmitting frequency information is to be stored at Frequency
No. zero, the following information must be programmed at this
Frequency No.:
Input address = 0
Control bit
= 1
BAND = 1111 (Keying the transmitter will be inhibited)
MODE = 0
Synth. freq. = 5999.9KHz
