IRLP Nodes 5160 & 3908
Node Guidelines:
To call a Node or reflector:
* Please listen for 30 seconds to see if the
node is already in use.
* Put out a call asking if anyone is using the
IRLP and then wait 30 seconds for a response.
* Following this, state your call-sign and
announce the node number you wish to call. E.g. This is ky0bbo
calling node 1234 on the IRLP. Immediately after announcing
this, dial the node number you wish to call.
* To connect to a Node or reflector, Dial the
Node Number with your DTMF keypad.
* After connecting to a node, listen for 30 seconds to
ensure you don't interrupt a QSO. Your then free to put out a
call.
* During a
QSO, please pause 2 seconds (minimum) before keying up to allow
other stations to disconnect or break in.
* When
connected to a reflector or node, key your radio then wait one
second to allow the other node/s to begin transmitting.
* To Disconnect from a Node enter
"73". NOTE: You can only enter a
disconnect code when the link is idle. If the operator on the
other end is long-winded, you're at his mercy, until the node
timeout breaks in. An 8 minute timeout has been set to drop
the node if no audio is detected from this end.
* There are no "access codes" for
this node. It's open for everyone to use. Enjoy

What is a Node?
A Node refers to a computer that is either connected to a
repeater or runs on a simplex basis. Nodes can be connected to
each other in 2 different ways The first way is Node to Node, and
the 2nd is via a reflector. Node to Node is virtually 2 linked
repeaters located anywhere in the world on the IRLP
system.
What is a reflector?
A reflector is a computer allowing multiple nodes to connect
simultaneously e.g. If I was talking to node 6220 and we both
needed to talk to node 6000, we could all dial in to a reflector
and be all connected simultaneously. More than 20 nodes can
connect to a reflector simultaneously.
The reflectors have 10 'channels' each. You can access these
different channels by dialing the three-digit reflector number,
plus a channel number from 0 to 9. For example, channel 3 on
Reflector 925 would be "9253". The most commonly
used channel on a reflector is channel 0.
Two of these new channels, 8 and 9, have a special purpose. They
use a special audio encoding method so that nodes on dial-up
connections can now use the reflectors. This means very little to
us locally, except that if you want to talk with a group on a
reflector that includes a dial up node you'll have to be on
channel 8 or 9. However, if you're making a direct connection to
a dial-up node there is no difference.
Node Information
and Short Operating Guidelines
* To Connect to Another Node: Enter the node
number.
* To Disconnect from the Node: Enter
"73"
* Note: You can only enter a disconnect
code when the link is idle .i.e. no radio traffic
* Node to Node timeout: 8 minutes
* Node to Reflector timeout : 20 minutes
* There are no access codes on these nodes
About Node Timeouts:
* The timeout for reflectors has been set to 20
minutes. e.g. If no one transmits locally for 20 minutes the
reflector will disconnect.
* The timeout for Node to Node QSOs has been
set to 8 minutes. e.g. If no one transmits locally for 8 minutes
the node will disconnect.

* PL (CTCSS) Tone: 123.0
Node Technical Information:
Node 5160
* Node
Computer: Pentium II 300Mhz
* Operating System: Linux 62 Redhat
* Radio TX/RX: Yaesu FT1500
* Antenna: X500HNA DIAMOND - 144Mhz -
8.3dB/ 440Mhz - 11.7dB @ 25 feet, Length 17 Feet
* Power Output: 100W ( currently testing

Coverage:
The Node has excellent
coverage over the entire Sioux Falls Area extending in all
directions. The node works well for mobile units up to 25 miles
from Sioux Falls. There is good handheld coverage of the downtown
area, as well as the entire Sioux Falls Metro Area.
Node
Number: 3908
* Location: Sioux Falls, South Dakota

* PL (CTCSS) Tone: none
Node Technical Information:
Node 3908
* Node
Computer: Pentium II 300Mhz
* Operating System: Linux 62 Redhat
* Repeater: GE Master Exec II
* Antenna: X500HNA DIAMOND - 144Mhz -
8.3dB/ 440Mhz - 11.7dB @ 25 feet, Length 17 Feet

Coverage:
The Node currently covers the
Sioux Falls area. When relocated to the new location coverage
should improve immensely.

Latest IRLP News: During Space Shuttle flights the node
will be connected to the NASA mission control feed for
approximately 70% of the time. From time to time the node will
also be connected to Live Hurricane Nets.

Latest News: My repeater is up and running on 442.000Mhz,
+ (447.000Mhz). I'm working on putting the repeater on a 240ft
tower. This should give some great coverage of Sioux Falls and
surrounding areas. My second IRLP node will be operational full
time on this repeater shortly.
Other projects in the works:
? Build a VHF repeater for node 5160 (Already started)
? Install my APRS unit in SUV full time (completed)
? Possible construct a 6M Simplex Node linked to one of the
repeaters (on Hold)
If anyone in South Dakota, North Dakota, Southern Minnesota or
North West Iowa would like help in building an IRLP node, please
let me know. I'd be more than happy to assist.
