Radio Settings.

To use a simplex gateway you need to listen and transmit on the same frequency,  MB7INM transmits and receives on 145.2875MHz and requires a CTCSS tone of 82.5Hz. 

MB7INM is permanently connected to a group of local repeaters, GB3BY Chorley, GB3EG Wigan, GB3FC Blackpool and GB3PN Lytham. 

All simplex gateway nodes are licensed for narrow deviation only so please make sure your radios are set to narrow. If you operate your radio in wide deviation mode you could cause distortion and your signal may be dropped by the gateway radio. Leave a gap of four seconds between overs to allow all linked nodes to reset and for anyone else to join in. Before transmitting into a gateway please listen for a while to make sure it's not in use. Two people can use the same gateway to talk with other users but as it's only simplex you will be hearing the other local user directly from their radio to yours.

The tones from the gateway assist with determining who is operating from where.

When you transmit into the repeater and it's connected to another node, as you unkey, the gateway will reply with a morse K (dah-dit-dah) with a higher frequency of 1200Hz.

When you transmit into the repeater and it isn't connected to another node, as you unkey, the gateway will reply with a morse K (dah-dit-dah) with a lower frequency of 800Hz.

When a remote user on the network ends transmission you will hear a morse I ( dit-dit).
