Text Box: MB7IFH

MB7IFH is a development node located at the QTH of G4RKY in Shipham, Somerset.

Its primary function is for test and development using the Allstar platform. That’s a posh way of saying that Matt uses this to try out new ideas before deploying them on the main repeaters!

The first of those is the Allstar Web Transceiver, which works well on ‘IFH

The first thing to remember about MB7IFH before you start to use it is:




With a simplex link, you may not be able to hear the station that is working the link—its not like a repeater where everyone can hear everyone else!


If no links are connected, if you can reach the node, Alison will respond with “All Links Disconnected”. If a connection is present you will hear a “K” tone ( dah-di-dah ). You can then find out what is connected by using the *70 code as detailed below. Please check no-one is using the link before disconnecting.


Here are the DTMF codes to control the link:


*70           Check link status

*72           Last node to key us up

*73           All connected and onward connected nodes


*10           Disconnect last connected node


Allstar Nodes:

*3nnnn    Connect to Allstar node nnnn

*1nnnn    Disconnect Allstar node nnnn


Echolink Nodes:

Note: any node numbers lass than 6 digits need to be padded to 6 with zeroes. i.e. Echolink node 1332 must be dialed as 001332

*33xxxxxx             Connect Echolink node xxxxxx

*13xxxxxx             Disconnect Echolink node
