<div class="moz-cite-prefix">Some repeaters like Tait, Vertex, and
others have simple repeater controller functionality built-in. In
some cases, all it takes to enable/disable the internal controller
is one logic line. In cases where I cannot afford to have a
repeater fail if the computer dies or the USB radio device stops
responding, I have used a simple circuit that looks for the flashy
- flashy on the FOB, and if it fails, reverts the internal
controls. <br>
<br>
Scott Zimmerman (and I) have developed a new USB radio interface
device that has this functionality built-in. The new device will
be ready for full production in a few weeks.<br>
<br>
Our interface is like most USB radio devices in that it converts
the USB to audio and signaling, (it's CM119 based) but is also
includes some other features not currently included on the
interfaces available today. One of those features is monitoring
the health of the computer and interface. If the LED stops
flashing, a pin will go to the opposite logic state and allow
control to revert to internal controls, or another device like a
in-between repeater controller. The source of the health circuit
can be slaved from the LED or GPIO1, and is capacitor coupled so
it doesn't matter if the input fails to ON or OFF - it still has
failed, and will revert.<br>
<br>
There are several other features that address a number of
compatibility issues. One of these features allow this interface
to be connected to a radio, or invert the logic to allow easy
connection to a controller. The logic is programmed by solder
jumpers. The audio filters have been pushed out some, but more
importantly have more poles to insure none of the clocking gets to
the modulator in instances where the interface device connects
directly to the modulator. There is an on-board DC to DC
converter so you can take advantage of higher audio output levels
without needing to route a source of 12 Volts to the device.
Several audio levels into and out of the device are possible
without the need of additional attenuation or amplifiers.<br>
<br>
Watch for the release of this new product soon - the Repeater
Builder USB-RIM.<br>

If it involves the use of an external controller, then that's

I still use my RC210s at all my sites. I have a lot of
confidence in AllStar running a repeater but the controller is
one thing I have a hard time letting go. I deal a bunch with
PCs and no matter what OS you are using, they will lock up
eventually because of hardware, heat, etc. I had a site that
had a good PC, but every once and a while, the machine would
lock up or do something and allstar would halt. Couldn't even
remote in. So, I had to go to the site and reboot just to get
the machine back on the air. After the third time, I
reinstalled the controller. Machine was still flaky but all I
lost was the link and the repeater was still on the air.<br>
