Very cool. Just what I am looking for...although it doesn't look
like the PCGM has made it on the web site for sale yet...at least I
couldn't fine it.<br>

The PCGM (Programmable Clock Generator Module) is a device used
for some configurations<br>
of simulcast with the RTCM. For transmitters that can "swallow"
a 10 MHz external reference clock source<br>
(such as the Motorola Quantar, etc), all you need is the output
of the RTCM driving the direct <br>
modulation of the transmitter. For radios that do not have an
external reference clock source<br>
(or have one, but not at 10MHz), the PCGM will take the 10Mhz
reference from the GPSDO (generally<br>
a Trimble Thunderbolt) and "make" whatever frequency your
transmitter needs for a reference<br>
(at least one of 17988 frequencies possible). Transmitters that
do not have an external reference<br>
clock input at all generally need to be modified to disconnect
the normal internal reference oscillator<br>
and make provisions to allow injection of the reference clock
frequency from the PCGM. <br>
<br>
In addition the PCGM also generates the voltages (3 of them, I
believe) to run the Trimble<br>
Thunderbolt, with a single (generally 12 volt) input to the
PCGM.<br>
<br>
These devices are available for sale from the Micro-Node.Com
site.<br>
<br>
There was also a question on the list about the ClockSynth
project. This was merely an initial prototype<br>
to prove the base design of the PCGM. There were only 2 boards
of this type built. They worked and<br>
demonstrated the validity of the general concept from which the
PCGM was then based.<br>
