Dick,
There are no fixed periods. The essential thing is to keep QSOs as
short as possible.
A typical minimum QSO might be:
CQ G3XDV K
(note that 'de' is never used and only one
callsign is sent)
G3XDV PA4VHF K
PA4VHF XDV O O K
(just the sufffix is used after full callsigns
have been exhanged. Reports are O for
100% readable, M for readable with difficulty,
and T for unreadable)
XDV VHF R O O TU SK
(use TU for "thank you")
VHF XDV R TU SK
(and that is the end)
When there is more time, you might give a locator. Some stations send
"73", but this is very time-consuming. A question mark is used as a
short form of "QRZ?"
For an expedition things might be even more brief as they are on HF
(but some people argue that full calls must be exchanged to make a
valid QSO). Perhaps an expedition with callsign LX1XX might have QSOs
like this:
CQ LX1XX
XX G3XDV K
G3XDV O K
R O SK
R SK
XX G3YXM K
G3YXM O K
R O SK
R SK
and so on .....
There have been QSOs where the DX station works two people at once
since two QRSS stations can often be copied at once, but I would not
recommend this.
I do suggest that before you leave home you notify this group of your
transmit frequency (say 137.730kHz) and a receive range (say 137.680-
137.690kHz) and try to operate split to avoid long delays when
unsuccessful callers are still on your frequency.
Hope this helps.
