The big question is:
"How does the ID-O-Matic
IV
compare to the ID-O-Matic II and III?"
The big news -- VOICE ID is available as a low-cost option!
All IDs are "polite"
. Morse code IDs are attenuated if the repeater is in use. Voice IDs are replaced by a Morse ID if someone is talking. And, you can set an optional early ID timer to let the ID-O-Matic IV try to ID when the repeater is idle.
A
real-time clock
lets you synchronize beacons to the clock time, and can even be kept accurate with input from a
GPS receiver
.
"Quiet time"
lets you silence beacon transmissions during selected hours (like at night).
The circuit board is slightly larger than the -III (3" x 1.95" / 7.6cm x 4.95cm) , keeps the same connector locations, and the same mounting hole locations.
The DB9 connector and serial port used on the ID-O-Matic II are replaced by a
USB
mini-B connector.
The 10-pin terminal block used on the ID-O-Matic III is replaced with a 12 pin block. The pinouts are similar. There's a second ground for the audio output, and an added an output to indicate when the ID-O-Matic is sending an ID or a beacon.
A dedicated output can switch power to a cooling fan, with user-specified turn-off delay.
All I/O signal polarity is set via the setup menu; there are
no jumpers to set
.
The board is better optimized for repeater use, with improved volume control.  Receiver audio has enough gain to drive virtually any repeater setup due to the on-board low noise audio amplifier.
A protection diode prevents damage to the board if power is connected backwards.
Terminal block pins are marked more clearly.
The setup menu is vastly improved. As before, no special software is needed -- the device shows up as a regular COM serial port (but needs no tricky serial configuration).
The new bootloader software enables
field upgradeable firmware
. You can load new firmware using a very simple process, no special hardware or software needed. Installing new features or bug fixes takes about five minutes.
There's no need for a separate power supply during setup and testing -- power can be drawn from the computer's USB port. This also enables a handy backup power source in the form of a cheap, readily available mini-USB cell phone charger, or a battery with a mini-USB connector attached.
Random beacon timing option - great for fox hunts!

The
ID-O-Matic IV
is a multipurpose, microcontroller based device intended primarily for repeaters, but with other uses as well. With a heritage dating back to the original ID-O-Matic featured in the 2008-2012
ARRL Handbook
, its primary application is that of a simple but feature-laden repeater controller with automatic Morse code station ID. It can also be used for beacons, fox hunt transmitters, automatic station ID and many other uses.
Thousands of ID-O-Matics have been sold to hams around the world
and are in use in beacons, repeaters, link transmitters, Echolink & IRLP stations, and even providing automatic CW ID for HF, VHF and UHF stations.
So what are the more interesting features? There's a programmable delay timer that announces your call sign or any other message, in Morse code at a speed and audio tone you choose. Then there are the CW keying and PTT outputs so you can attach it to a transmitter, transceiver or repeater. The COR/squelch input can be used to make a repeater controller/IDer that works the way you want it. And how about a new USB interface to connect to your shack computer, laptop or terminal for quick and easy configuration? It's all there.
Using the built-in USB interface, connect the ID-O-Matic IV to a PC (Windows, Mac, or Linux) with a free terminal emulation program such as PuTTY or Minicom and you can use the simple menu to configure the ID-O-Matic IV the way you want it. Just type in your ID message. When the COR input is activated the
ID-O-Matic IV
will send the message at regular intervals.  And now, with the optional add-on
voice ID board
-- record your own voice ID and use that instead of (or in addition to) Morse code!
The COR input is used to control when the
ID-O-Matic IV
sends your programmed Morse code ID. You can use a squelch, COR, PTT or other signals from your equipment according to your needs. The built-in interface circuit and programmable signal polarity let you use either active-high or active-low input signals. You can optionally have the ID-O-Matic send a courtesy beep (or up to three Morse code characters) at the end of each transmission, and you can specify a "hang time" to keep PTT active for a brief period after the input stops. If you want the repeater to ID every so often when it's idle, there is a beacon timer
and a separate message for that too
. You can, for example, have the repeater ID with its call sign while being used, and a longer message every hour or two when it's idle. Or use Morse for the regular ID, and a voice announcement for the beacon. The ID-O-Matic IV has a real-time clock, so you can synchronize the beacon ID to the wall clock if you want.
There's a PTT watchdog timer to keep your repeater from being "hung" by stuck mic buttons or long-winded users. And, you can use the ALT MSG input to send a different ID message (and even change the courtesy beep) based on the state of an input signal - useful if, for example, your site switches to backup power, or if a link is active. For an example of how you could use the ID-O-Matic IV in a repeater setup, there is a nice write-up here:
http://www.repeater-builder.com/kenwood/pdfs/tkr-n20-idomatic.pdf
Regardless of the mode used, the PTT output is active during the CW ID, with a programmable pre- and post-ID delay. Speed is variable from 5 to 40 words per minute, and the audio pitch for the CW ID and the courtesy beep is also programmable via the setup menu. All outputs are equipped with robust 2N7000 MOSFETs that can handle up to 60V at up to 200 mA to key transmitters or other loads.
Improvements have been made to the original ID-O-Matic's Morse audio output. The -IV boasts a smooth, nearly pure sine wave audio signal rather than the raspy square wave found in some ID circuits.
The on-board Morse ID is filtered and fed to a passive audio mixer with volume control. An input is provided for external audio from your receiver or other source; this input has a low noise audio amplifier IC with volume control and is mixed with the Morse audio. There is a de-emphasis filter on the external audio input that can be included or left off at build time, depending on your needs.
"Future-Proof"
: The heart of the ID-O-Matic IV's functionality is the firmware program that controls the processor. The controller can be upgraded with new firmware in minutes, without the need to return it for programming, swap chips or even remove it from the repeater (although a few minutes of down time is required). New features are planned for future release, giving you added capabilities at no added cost.
The
ID-O-Matic IV 4 from Radiodan is completely professionally built and tested.
All you need to supply is a source of DC  power (unless GM/CDM cables are ordered, then power is taken from the Motorola receiver radio)
