EchoLink and IRLP are both voice over internet protocol (VOIP) technologies specific to amateur radio. IRLP ( was created in the 1990's by David Cameron, VE7LTD, and EchoLink ( was created sometime later by Jonathan Tayler, K1RFD. Several thousand nodes exist all over the world and can be found online at their respective websites.


Bear River Amateur Radio Club members are welcome to use K7CDD's Raspberry Pi based EchoIRLP node implementation by tuning to simplex frequency 447.800 Mhz using a PL tone of 71.9 Hz.

Before utilizing the EchoIRLP node, please check the node status by holding PTT and dialing "A1" on your keypad. The node will response with it's current status. If the node is not in use, you can call any IRLP node by simply holding PTT and using your DTMF keypad to dial the target node number. To call any EchoLink node, press the "A" key followed by the target node number. After you've dialed the number, release PTT and wait a couple of seconds for connection confirmation. If no confirmation is given, try the process again as the system likely did not recognize the DTMF code entered. You can also connect to conference nodes on both systems. IRLP has given conference nodes the name of "reflectors". A popular IRLP Reflector for our area is the Alaska reflector on node number 9077. As always, ensure you are following FCC rules by properly identifying and pausing before transmissions to ensure the system isn't already in use. It's also a good idea to hold PTT for a second or two before talking to allow the VOIP system to establish a connection.

Once you're done using the node, dial 73 to disconnect. If you'd like to check the status of the node at any time, dial A1. The node is in Cam's basement, so the range isn't huge, but feel free to give it a try! The node status is below for your convenience.
