Echolink Node

My Node Status, MB7IWG-L, is listed here (is there another way to do this?)

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 Echo123, K for Local and I for Internet.
Please leave a pause to allow for these tones before transmitting. Thank You

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
