After we have found the rod position of the Grundstellung and the Stecker it only remains to find the Ringstellung. Usually this would be known already, as, at this period, the wheel order and Ringstellung were only changed about once a fortnight. However if these have just been changed it is necessary to read one message. This could always be done, as a great many messages were sent in two or more parts. In such cases the call signs and signatures of the parts were essentially the same, and the parts after the first began by saying that they were continuations, giving the time group of the last part of the message as a reference.

Making Contact – All that is required to make a contact with another station (calling
CQ) on a local repeater is to push the PTT switch on the microphone and give your call
sign. If the repeater is quiet, just say your call sign, to attract someone’s attention. You
will then hear a funny noise, that is the unmodulated repeater carrier, for a second or two.
This is what’s called the squelch tail. It lets you know the repeater is working. If
someone is interested in speaking with you, they will call you after you give your call.
Some repeaters have specific rules for making yourself heard. In general, however, your
call sign is all you need.
