IRLP Node 4676 comprises a standalone Micro-Node running the Centos 4.8 Linux 
operating system connected to an
Alinco 
DR-235T 222mhz
FM rig.  A powerful PC is not needed, the audio bandwidth
is about 
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
address.
How to Access IRLP via Node 4676
	- 
	
		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, 
		channel or reflector number (click HERE for a list of 
		nodes) you would like to contact. 
- 
	
		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 
		(a reflector is just like a repeater
 so use normal repeater protocol, guidelines
		
		HERE).
 
- 
	Be sure to allow
		several seconds after keying up before speaking to allow the connection 
		across the Internet to send audio to the distant end.  If you
 don't do this, the first word or two will be chopped off at the distant 
		end.
 
- 
	
		When the session is finished, wait 
		for a silent period and then touch-tone in "73".  You will hear the station you were connected to ID. 
		Remember, you
 must type in the 
		"73" while
		the distant end is idle.
 
- There is a time-out timer, 
	therefore if you are only listening the connection will automatically shut 
	down after a few minutes. Of course, if you are 
 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 
	the IRLP site.
