DSC OPERATION

D

Test call

Testing on the exclusive DSC distress and safety calling
channels should be avoided as much as possible. When test-
ing on the distress/safety channel is unavoidable, you should
indicate that these are test transmissions.
Normally the test call would require no further communica-
tions between the two stations involved.

Test Call

” in the DSC menu.
