CCIR493 Selcall Controller for ICOM
Price $150.00 + postage. GST free.
- Adds CCIR493 HF Selcall encoding and
capability to ICOM transceivers.
- Send a selcall at the press of a switch.
- Automatically responds to incoming
selcalls with a revertive tone and blinking display LEDS and audio
- The Senders selcall number is stored in
receiving ICOM radio together with the time in minutes since the selcall was received.
- Allows selcall scanning of up to five channels
receipt of a selcall, the ICOM can transmit a local area alert
on a VHF or UHF frequency.
- Once settings are loaded they are
EEPROM, so COOEE can then be used on a non-Icom radio, with reduced
- Adds Codan syle "Roger beep" when PTT is released.
Australian designed and built at Waikerie S.A.
- Empty radio memories
- Set the radio address to
- Set the radio baud rate to 4800
- Nett the radio
- Plug COOEE into the rear of the ICOM
accessory socket and the CAT socket.

a selcall by pressing the SEND switch.
you receive a sellcall the RED led will blink then the RED and GREEN
leds will blink continuously. Control
line D12 will go high for 1 second. The
senders selcall ID will be loaded
into Memory 42 for later redisplay, and COOEE will send
a revertive tone sequence. (Memory 42 is cleared at powerup/reload.)
beeper will beep and the LEDs will blink untill PTT is triggered.
you have a freq > 100Mhz loaded into Memory 45, upon receipt of a
selcall the ICOM will also send a revertive tone on that frequency,
typically it would be a VHF or UHF FM freq, to alert a handheld radio
that an HF selcall has been received.
For IC706 MKIIG radios Menu item 30 VSEND SEL must be set to OFF,
otherwise PTT will not key up on the VHF freq.
To send a Beacon call, put 1000001 in Memory 51, and all sent selcalls become Beacon calls.
the AUX line in pulled low, COOEE will scan the following memory
channels in order 41,46,47,48 and 49. Empty channels will not be
scanned. The default selcall preamble is 2 seconds, with the call
channel lodaed into MEM41.
Each additional channel (46 - 49) adds
1 second to the selcall preamble. With all five selcall scan
channels loaded the preamble is 6 seconds.
Full Microprocessor Reset.
Holding the SEND line low whilst rebooting COOEE resets the EEPROM values to:
CAT address 48 hex
My Call 1234
Target Call 5678
the switch to the SEND
position has one function.
- Send a selcall or send a Beacon call
the switch to the RELOAD

- Read in new updated Selcall numbers and
- Clears MEM 42 & MEM 43 (last received selcall number) and
- Reset COOEE.

In the event COOEE is to be used with a non-Icom radio the
selcall numbers can be loaded via serial port using a RS232 to TTL level converter eg.MAX232.
