So, your shiny new DMR radio has arrived. You’ve obtained the programming software and necessary programming lead, stuffed in a few channels and ‘hello world, here I come’. But how to wet your feet in DMR without sounding like the newbie that you are?
First, DMR operation does share some commonality with ‘normal’ FM repeater operation. However despite the availability of worldwide communication little similarity to HF operation exists. Remember, one reason you have just spent some of your hard earned cash is to sample the ‘crystal clear’ audio quality of digital radio. It therefore makes little sense to repeatedly, or singly, call CQ. Leave that to the DX bands where it serves the purpose of enabling station discovery and tuning.
Second, think about how DMR works and what you are saying. You listen through a repeater but listen on a talk group.
Third, when you call say what talk group you are calling on. For example if I am scanning all the ‘channels’ on GB7MB and hear a station calling ‘G9ZZZ listening through’ by the time I have looked at the display of my belt mounted radio I have no idea what time slot/talk group G9ZZZ was calling on. better to say ‘G9ZZZ listening world wide’ or ‘G9ZZZ listening MB local’.
Fourth, treat the limited resources of the DMR-MARC network with respect. If you need to do testing, do it on the local non networked channel. Avoid long QSO’s on the world wide talk group, the suggested polite limit is 2 minutes. Move to a more local talk group if possible.
