WHERE AND WHEN ARE CLUB MEETINGS HELD?
We are a small informal club mainly comprised of a few family members and friends so we do not have formal meetings. We’ve never really had the time to invest into meetings or formal gatherings. We would be interested in pursuing that if someone wanted to take that on.
WHAT IS EXPECTED ON THE REPEATERS?
The FCC requires that amateur radio operators give their station call sign every 10 minutes and at the end of the conversation. We also believe and enforce giving station call sign before you dial up or communicate on the nodes. This is because many times we have run into trouble on the reflectors because a user would not abide by the reflector rules (not ours) and get the node blocked from the reflector and since they never gave their call sign, then there is no way to get in touch with the user to explain the rules. We reserve the right to shut down any node, repeater or both when people cannot identify themselves on the repeaters. Also if someone dials up a node without identifying first, then the user may be connecting in the middle of an ongoing conversation on the other end. If this conversation goes on more than 10 minutes, then the local user would not be able to abide by the FCC 10 minute ID rule without interrupting another conversation.
We expect courtesy to others while using the repeaters or nodes. Do not use profanity or treat others with disrespect. If someone is jamming the repeater, just sign off and do not discuss it on the air. When you do, you are giving them what they want, attention. If you must talk about it, go to our FACEBOOK GROUP and discuss all you want.
WHERE ARE THE REPEATERS?
The repeaters are in the Oklahoma City suburb of Del City, Oklahoma City, Oklahoma USA. It is located on the Southeast side of the metro area near Tinker Air Force Base. Del City is the nearest suburb to downtown Oklahoma City. Physically the repeaters are 110 feet above the ground and are between SE 15th Street and SE 29th Street, and between Sunnylane Road and Bryant Avenue. The two meter antenna is at the top, 110 feet, and the 70 cm repeater is on the South side of the tower with the top at 95 feet. If you want to find them, just go to http://aprs.fi and search for IRLP-4122 and you can see them on the map. It sends out beacons on APRS.
WHAT IS IRLP?
Internet Radio Linking Project (IRLP), the name given to a voice over IP system, based on a Linux version of Speak Freely. It is used for communicating long distances, using repeaters connected to the Internet. A repeater connected to the IRLP system in Oklahoma City can easily connect to a repeater thousands of miles away by simply entering a DTMF node number of the distant repeater IRLP node. One of the high points of IRLP is that each node has a 128 bit Pretty Good Privacy (PGP) encrypted key. When a node is dialed, the remote node verifies our PGP key to see if our node is legitimate or a hacked system. IRLP is only accessible via a radio, meaning that you cannot communicate through a connected computer using the computer microphone. IRLP is very secure and has superior audio because of the audio codec used is more wide band. It requires a greater Internet bandwidth than Echolink and is a bit more difficult to set up. It is not a digital system like D-Star, or System Fusion, though it does convert the analog audio into a digital signal as it is transmitted over the Internet and then reconverted back to analog audio on the other end. All is needed is a two meter or 70 cm analog radio with DTMF and CTCSS capability.
WHAT IS VOICE OVER IP?
Voice over Internet Protocol (VoIP) is a system that takes audio from our repeater and converts it into digital data. That data is transmitted over the network (Internet) to remote nodes. The remote node computer takes the data and converts it back to analog audio for the users on the remote end to hear. Voice over IP is a widely use technology today carrying voices over the Internet as data much cheaper than using a standard telephone. In fact, most cellular telephone companies today are already doing this.
WHAT IS A NODE?
A node is the name that refers to a computer access point. Every node is assigned a node number. This is analogous to a telephone number. Our repeaters have node numbers that correspond to the computer access point attached to them.
WHAT NODE NUMBER ARE WE?
An occasion may come when we may be connected to an reflector that a person on the other end may ask you what node you are on so they can call you direct.
146.700 MHz IRLP is 4122 – ECHOLINK is 164667 (W5DEL-R) is a repeater
443.300 MHz Allstar is 28941 – ECHOLINK is 794636 (W5DEL-L) is a repeater

WHAT IS A REFLECTOR?
A reflector is a special kind of node used on IRLP that allows multiple repeaters and simplex nodes from anywhere in the world to connect simultaneously. This way when one person speaks, all connected nodes will hear it and therefore all of the people in the listening area of those nodes will hear it. A reflector node number always begins with a nine (9). The last digit of the node number signifies which of the 10 reflector channels it is. For example… If we dial 9451, we are connecting to the Dallas reflector 9450, channel one (1). This allows ample channels for multiple repeaters to meet up on a channel for a private meeting. The owner of the reflector has the power to block any node at any time. Reflectors may have ten channels but they are numbered 0-9, 9100, 9101, 9102, etc. Channel zero is the main channel.
WHAT IS THE WIN SYSTEM?
The WIN System, or Western Intertie Network, is repeater linking system originating from San Diego, California. It was created by Jeff (Shorty) Stouffer K6JSI. There are more than 90 repeaters throughout California, and throughout the world. The WIN System has some rules that must be adhered to and can be found here. We are confident you will love this system. Our 443.3 MHz repeater use to be a WIN System affiliate but we have decided that it is not beneficial to leave any node connected 24 hours a day simply because there is not enough control operators available to monitor it. Anyone may connect either node to the WIN System or any other reflector or individual node whenever they like. We just no longer leave it connected 24 hours a day.
HOW DO I MAKE CALLS TO IRLP, ALLSTAR LINK OR ECHOLINK AND HOW DO I DISCONNECT?
To get connect and disconnect codes, send an email to email@example.com with your call sign and simply ask for the codes and we will give them to you. We do not openly publish them because doing so opens the door for improper activity on the nodes. We freely give the codes out to licensed operators that ask so that we have some sense of order. If the operation becomes out of control, we can change the codes at any time and even make it a closed system. That is not our desire and would be a last resort.
DO YOU HAVE A FACEBOOK PAGE?
We do have a Facebook page located here but we prefer to use our Facebook Group. The reason we prefer the Group over the Page because a Group allows anyone in the group to post questions, announcements, or comments prominently in the Group. The Facebook Group allows greater interaction among the users. The Facebook Page can only be posted on by an administrator. Others can comment on the Admin’s posts but they are not as prominently displayed. You can feel free to join either or both as shown below…
