Yes, to dial up a frequency only takes a couple of seconds but if you do it "by the book" you would then call Stockholm Radio for example to check transmission/reception, get a Selcal check and if there are more than one box, it takes a little longer.
That's not what I meant - I meant that it's not difficult to make sure you either have the SELCAL not selected to HF, the HF's off, or the HF's on a non-used frequency. Takes scant seconds.
