Echolink Node

Please bear in mind, when connecting to my
node, that you may not get any replies when you call for a contact. The node is very new, and therefore does not have many listeners at present. It is hoped that as time goes by, more operators will use the node. The
RF side of Echolink now uses Courtesy Tones using
EchoNewsMP3Plus, K for Local and
I for Internet. |
Update... 29 09 2013 Antenna Repaired (Thanks Keith)
Update... 20 01 2016 NEW NODE CALL SIGN
Coverage over the last few
months has been terrible (only a few hundred yards)
thanks to Keith, everything is working again.
Just to clarify, the NOV for the MB7IWG link only allows for 1.5 Watts maximum output (3 dBW)
I NOW RUN UNATTENDED, SO THE NODE SHOULD BE ON 24/7
Echolink runs under Windows and uses Dimension 4 to sync the clock
