- ID timer/repeater controller with Morse code output
- Keyed CW, audio, and PTT outputs
- PTT/audio combination for keying HTs
- AMPLIFIED audio mixer for repeater audio and ID
- Optional de-emphasis for repeater audio
- Super-easy USB port for configuration
- Fan control with auto delay (200 ma MAX, fan relay option highly
suggested)
The big question is: "How does the ID-O-Matic IV compare to the
ID-O-Matic II and III?"
- 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!
- Many... many new or enhanced features - and even more to come!
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 an enclosure if desired
IN-STOCK for Immediate shipment. We get it out the same or next day depending on when you order.
