CONFIGURATION
In principle the ILER-DDS may seem very complicated, but it is not.
Prior to making any changes in the configuration you will have to study your project needs. Once you
know exactly what do you want and how to do it: configuration will be easy, simple and fun!
To activate the configuration menu you will have to power on the ILER-DDS while you keep
pushed the encoder. (push power-on).
On screen you will see the first entry of the configuration menu, and turning the encoder will cycle
through all the options. One of them is “EXIT”, which will allow you to go back and start up the ILER-DDS
normally without making any changes.
LOWER LIMIT:
One of the entries is “LOWER LIMIT”. This is used to set the band lower
limit. Make a quick push, then you will have the option of entering any
frequency in the range 0 to 40 MHz in 50 kHz steps.
This is usually the lower limit of the amateur band the receiver or transceiver
is prepared for, but it may be placed at whatever frequency you like, even
out of band. Once the frequency is set, make a quick push and the ILER-
DDS will start-up normally.
Note: If you plan to use the ILER-DDS as RF generator you may adjust the limits to the ones you like for
your generator, even 0 and 40 MHz!
UPPER LIMIT:
Keep turning the encoder until you see “UPPER LIMIT” when you want to
set the band upper limit. Make a quick push, then you will have the option of
entering any frequency in the range 0 to 40 MHz in 50 kHz steps.
This is usually the upper limit of the amateur band the receiver or
transceiver is prepared for, but it may be placed at whatever frequency you
like, even out of band. Once the frequency is set, make a quick push and
the ILER-DDS will start-up normally.
YOUR CALL ?:
Keep turning the encoder until you see “YOUR CALL ?” and make a quick
push. You will program a welcome message at turn-on, typically your
amateur radio callsign.
With a quick push you will cycle between “CALL ON” and “CALL OFF”.
“CALL OFF” may be selected with a quick push when you do not want any
welcome message.
Should you want to program a message, go to “CALL ON” and make a quick push. Now you will se the
last programmed word (i.e. EA3GCY). You may enter up to 8 characters on the top line. The underline
shows the position to be programmed. Turn the encoder to cycle between letters, numbers and symbols
for each position. Once you are happy with the character selected make a quick push: the character will
get stored and the cursor will move to the next position. Complete all 8 positions. One of the available
characters is an empty space which may be also used. You will have to go through all 8 positions, even if
they are blank spaces to complete the process. After the 8th position is programmed, a quick push will
complete the process and the ILER-DDS will start-up normally.
