5.Press SELF (F2) to start the self-call.

6.You may select now a specific channel to perform the call, by pressing CHAN (F1). See details on page 27.

7.When ready, press SEND (F1) to start transmitting. The display alternates between your self-address and the channel used for the call is sent. If you did not select a specific channel, the channel number changes as the radio sends the call on each channel assigned to the selected net.

After all the channels have been used, the call automatically stops.

You can press STOP (F1) at any time to end the call sooner.

The bidirectional handshake is used to exchange LQA scores with other stations without establishing a link.

options).

A bidirectional handshake can be carried out with a single station or with all stations in the net. It can be carried out either on a single channel, or on all the net channels. When required, a message can also be added to the procedure.

After a bidirectional handshake with a single station, the LQA matrices of both radios are updated. The operator can then initiate a call to that station and obtain the best channel automatically.

When the bidirectional handshake procedure is performed with a net, all the stations in the net update their LQA tables.

MICOM-2 will wait for responses for a certain time before entering the link state with all the stations that responded within this interval (the maximum number of stations that are accepted in a bidirectional handshake is 16).
