George Smart - M1GEO

An online scrapbook full of half-baked projects and silly ideas.



My EchoLink node, M1GEO-L (524497) went off air in September 2014. This page remains as a reference for those interested. It was an SvxLink node supporting various services, including EchoLink. The link was running on a Raspberry Pi. More information on the technical aspects can be found on my EchoLink On The Raspberry Pi page.

A Quick Guide

The SvxLink node is split into modules. These include a simple parrot module to allow you to replay transmissions for testing (module 1). Another module, relevant here is the EchoLink module, which allows SvxLink to interface with the EchoLink system (module 2). Module 10 is the Propagation Monitor module, which collects propagation information from GoodDX and DXMaps. To select a module, you need to enter the module number, followed by # (hash). The hash is the terminator, and is always sent to terminate a string of DTMF instructions. You can key 0# to get help at any point, or *# to get the current status of the node.

Before connecting out, I suggest that you experiment with the features on the node and check audio with the parrot module. There are many options for each module, so one you have selected a module (module number followed by hash) try requesting help (0#).
