3.11.5
Information about the transmitting mode of every Frequency No. in use
must be stored in the memory, whether it is a radiotelephone frequency
(A3A,A3J, orA3H)or a wireless telegraph frequency (Al, A2H, or Fl).
3.11.6 Programming Frequency No. zero can be done in two ways.
If it is convenient that this Frequency No. contains the information
associated with an often used transmitting frequency, the programming
instructions do not differ from the instructions concerning any other
Frequency No.
On the other hand, if it is not desired to store any transmitting
frequency information associated with Frequency No. zero, this can
either be done as described in paragraph 3.12.14, if it is convenient
to let the local PROM-distributor do the programming, or in paragraph
3.13.22 If the programming is
performed by means of the optional
PROGRAMMING UNIT /241\
3.11.7 The easiest method of checking the programmed frequencies when the
PROM's have been mounted in the MEMORY /238\ is by connecting a
frequency counter to the output BNC socket, 231SK7, of the Exciter. The
output socket is the one carrying no colour code. It is normal
connected to the Transmitter Power Amplifier via a coaxial cable.
Unplug the cable and connect the counter to this socket.
The check is made with the SUPPLY switch in STAND BY. The frequency
measured is the transmitting frequency, ft. Radiotelephone frequencies
are measured in the A3H mode, DUPLEX. Wireless telegraph frequencies
are measured in the Al mode, morse key down.
3.12 Ordering programmed PROM’s
3.12.1 To make it possible for the local PROM-distributor to do the
programming the customer must fill in a Word Pattern Sheet, supplied by
the distributor, for each PROM which is to be programmed.
3.12.2 First of all one must find out which of the 32 input addresses of the
PROM corresponds to the wanted Frequency No. It is done in accordance
with table 3.12.1.
