MANUAL AND ALE PROGRAMMING
To use ALE, the databases in both the receiving and transmitting
radios must be setup properly. The following paragraphs describe
how the database is entered into the KCU 1051 using the controls
and display on the front panel of the KCU 1051.
MANUAL DATABASE PROGRAMMING
The manual database is entered on the manual page (MAN). There
are 100 manual channels available for programming. Each channel
holds four parameters: receive frequency, transmit frequency, modu-
lation type, and tune information. The frequencies and the modula-
tion type are entered manually. The tune information is stored when
a transmit is attempted on an untuned channel. An untuned channel
is indicated when a U is displayed in the last character position on the
top line of the display.
There are six fields that are cursorable on the manual page;
1. Operation/Mode field Selects different top level pages
ALE, SEND, MAN, SYS.
2. Channel Type ChMan, ChALE, ChITU and _____
3. Channel number 1 through 100
4. Communication type R&T, Rx, Tx (simplex, semi-duplex)
5. Frequency 2.0000 through 29.9999 MHz
6. Modulation type USB, LSB, AM, A3A
MANUAL CHANNEL PROGRAMMING
The operator must enter the frequency and modulation type for each
manual channel. Select the manual channel by placing the cursor
over the channel number with the cursor control and turning the VAR
knob to select the desired channel. After programming of the manual
channels is done, the KCU 1051 is ready to use in manual HF mode.
The first time a transmit is attempted on an untuned channel, the
radio automatically tunes and stores the tune information.
