TX/RX   145.2875 MHz  CTCSS 110.9   (Node encodes CTCSS 110.9)

Welcome to MB7IUK Allstar Node simplex analogue gateway in Manchester UK

Allstar Node Number 40535


Status: OFF AIR 17/08/2017 (2840_161017)

Due to Fault with GB3KU and them both being linked to the same GSM Switch, regretably MB7IUK has to remain off air until I get chance to look at GB3KU on Saturday 21st October 2017.


See who's connected?

How to get started with your own Allstar Node




28th June 2017

As the network MB7IUK is permantly on is very quiet these days I have decided to allow local Licensed radio amatuers to use this node. If it does get abused I will remove the ability for it to be remotley switched to different networks.

Please Note that after 15 mins of local RF inactivity (people talking into MB7IUK locally in GTR Manchester), it will default back to the UKHUB 2.

Wait for MB7IUK Carrier to drop then key up and dial DTMF

31st March 2017

MB7IUK was restored to service last night around 19:00, the SW update has not been completed. Apologies for the belated update to my 2 listeners ;O)


30th March 2017

Both MB7IUK and GB3KU are both off air for software updates, hope to have this completed by early this afternoon.


13:00 24th March 2017

New Diplexer arrived and installed, node back on air.


16:24 23rd March 2017

Diplexer replacement ordered, thought I had an origional Diamond, on having a conversation with a well know HAM radio dealer turns out that this was a cheap chinese copy. The VHF side of the diplexer was not affected and users of MB7IUK would have been none the wiser.

I should hopefully receive the Diplexer on Friday March 24th and will fit it straight away to bring the system back on line.


16:54 21st March 2017

Due to a Diplexer fault, MB7IUK has had to be taken off air and priority of the antenna given to GB3KU. The Diplexer fault was affecting GB3KU output power which was reduced by 75% for the duration of the fault.

Will try and get this fixed as soon as possible.


MB7IUK will operate on internal antenna only until Diplexer issue resolved.

Range will be significantly reduced and will be limited to approx 1 mile.



MB7IUK is now on air 24/7.


NOTE: If you notice anything wrong with MB7IUK or GB3KU (They are co-located and share the same antenna) then please let either myself Nick M0NCZ 07919 048347 m0ncz@raynet-uk.net or Jon M0RFU know 07842 230604 m0rfu@raynet-uk.net know.


About MB7IUK

MB7IUK is an analog simplex node which is located in the town of Ashton-Under-Lyne in Greater Manchester, UK. It is a "Pure" Allstar node, its node number being 40535. The Allstar "Node" software runs on a Raspberry Pi 2 Quad Core miniture computer, which runs 24/7. The RF access to the node is achieved through a Diamond V2000 at 600ft ASL and a  Motorola GM340 link radio. The GM360 receives the analog signal and then sends it out through the data port on the rear of the radio to a CM108 USB fob which was made by Alan M0AQC. The FOB then converts this analog signal into a digital signal and sends this to the USB port on the raspberry pi 2, where it is processed by the Allstar software on the node.

To access the node in Greater Manchester, please go to 145.2875MHz FM-N and use a tone of 110.9.

  • If you hear 1 tone, then the node is not connected,
  • if you hear a two tone (high/low) then the node is connected on the Allstar/Echolink network and is acknowledging that local RF traffic (ie what MB7IUK is receiving) is going through the node. Please be aware you may not be able to hear the station talking into the node as this is not transmitted out of the node, only received
  • If you hear a Family Fortunes type buzzer (der derh!), then the mode is in TX mode only and will NOT process any incoming local RF traffic.
