This feed relays traffic originating over an IRLP (Internet Radio Linking Project) node repeater with callsign G4CUI on a simplex frequency of 145.3375MHz. The
repeater is accessible only by licenced radio hams who use CTCSS tone access of 71.9Hz. The purpose of the IRLP node repeater is to allow radio hams to connect to other nodes world wide for the purpose of technical conversations, and the feed relays local stations on the uplink and remote stations (via the internet) on the downlink.
IRLP was invented by Dave Cameron VE7LTD as a means of connecting ham radios via the internet. My node repeater is part of that network and has been running since 2001.
