the correct DTMF tone. In that setting the display will show T-SQ. Compared to Europe,
CTCSS is more familiar in USA, where most repeaters use it for selectable functions.
Note: European repeater station are –in most cases- not transparent for CTCSS. This
means, that received CTCSS signals are normally not transfered to the transmitter. This
would require special decoders, encoders or regenerators. As a consequence, CTCSS
cannot be used if a conversation will use a standard repeater not specially equipped for
CTCSS. You may have a better chance if you use the highest CTCSS frequencies- test
it from case to case.
MEMORY : Programming of memory channels for frequent use. Before entering the setup
menu, you should select the desired operating frequency in VFO mode, repeater shift
and CTCSS setting. You can store a complete setting into each of the 10 memory
locations. All settings can be different!
• Start setup menu by FUNC longer than 0.5 sec. Memory is the first menu step.
ME is flashing. A memory location number appears below ME (1-0 or C for the
call channel). Free location numbers are flashing!
• Select the memory location with up / down or rotary knob.
• Press MR / MS at the radio front panel for saving the complete setting under this
location number.
A successfully saved memory location number will not flash any more and will remain
continuously on!
Erasing memory locations
• Recall the memory channel You want to erase.
• Start the setup menu step for memory (FUNC longer pressed, first setup menu
step ME appears)
• Press MR / MS at the radio’s front panel
After erasing the memory location, the location number will flash again.
DTMF: You can store up to 10 different standard numbers (similar to a phone number). Each
number can have up to 5 digits. You can select one of these numbers for auto
transmission, as soon as PTT will be pressed (next menu step dA, DTMF automatic),
or You use one of the numbers for Your own DTMF decoder (menu step dt MF on / off,
see below).
• Select address (1-0) first by Up / Down or rotary knob
• Enter the number (1 to 5 digits) digit by digit using the keyboard (e.g. 12345).
• Store setting with DTMF key on microphone.
dA: Activate (oN) or deactivate (oF) automatic DTMF transmission by means of Up /
Down-selection. If activated, the previously selected DTMF number will be transmitted
at the beginning of each PTT pressing. This is used e.g. for selective calling, if the other
party has a decoder.
Notes about DTMF:
You may also manually transmit one or more single DTMF tones as digits of a „phone number“ with Your
keyboard. Press and keep PTT button pressed at first. While still transmitting, enter the desired DTMF
digits into keyboard. Each digit will be transmitted as long as the digit will be pressed. Most selective
calling systems used in amateur radio accept manually entered numbers without problems. As a special
add-on your AE 540 is even able to transmit the additional DTMF digits A, B, C and D, so together with
1-0, *, # you have 16 different DTMF tone pairs.
dt If activated (DTMF oN), the speaker of your radio will be muted. If the distant party will
transmit Your decoder number (e.g. 12345), the speaker will switch on and You can
hear the transmission. This performs a selective calling system.
