IRLP Node 4676 comprises a standalone Micro-Node running the Centos 4.8 Linux
operating system connected to an
FM rig. A powerful PC is not needed, the audio bandwidth
8KB/s (64000kbs or 8bit word x 8khz sample compressed by a factor of 2 yielding
32kbs) and a low end, available spare PC is just fine. Before the addition of the new Micro-Node I was running a Dell PII 400Mhz machine with an old SoundBlaster ISA card. This worked great (see photo below) for about 6 years (24x7x365)! However, there is a requirement of
an always connected cable (or DSL) connection
with a dedicated or DHCP IP

Tune to 223.600 Mhz,
simplex with a 141.3 Hz PL tone. Make certain the frequency
is idle with no ongoing QSO.
Touch-tone in the 4 digit node,

Wait until you hear the station you are
connecting to identify itself.
Pause a few seconds to make sure
there is no ongoing QSO and then make your call to the node or reflector

carrying on a conversation the connection will not time-out. Be sure to
disconnect when you have completed the call.
- Before you utilize this node please make
certain you understand ALL of the operating procedures by going to
