[Dx4win] Prefix Logic

[WO2N]

Okay that makes sense, tnx. That's previously stated. That's what I wanted
to know so I can take a reasonably close guess when Prefixing searching.
BTW
Here are my Malpelo QSO's, maybe it will help data base :
    Date	               Time   	Band	Mode	Call sign
Country	Conf	Label	Zone	QSL Date	QSL Mgr	Callsign Notes	QSO
Notes
3/11/1990	23:41	14MHz	CW	HK0TU	Malpelo Island	Y
9	29/12/01	HK3W		
4/11/1990	11:55	14MHz	SSB	HK0TU	Malpelo Island	Y
9	29/12/01	HK3W		
5/11/1990	23:30	21MHz	CW	HK0TU	Malpelo Island	Y
9	29/12/01	HK3W		
6/11/1990	20:52	21MHz	SSB	HK0TU	Malpelo Island	Y
9	29/12/01	HK3W		
16/04/01	18:20	28MHz	CW	HK3JJH/HK0	Malpelo Island	Y
9	29/12/01		Op Pe	
26/04/01	0:30	7MHz	SSB	HK3JJH/HK0	Malpelo Island	Y
9	29/12/01		Op Pe	
1/5/2001	23:17	18MHz	SSB	HK3JJH/HK0	Malpelo Island	Y
9	29/12/01		Op Pe	
21/06/01	23:57	14MHz	CW	HK5QGX/0M	Malpelo Island	Y
9	21/09/02	JA0MGR		
23/06/01	0:07	18MHz	SSB	HK5MQZ/0M	Malpelo Island	Y
9	29/12/01		862,

The simple answer is that if a sub-prefix can be specified that is unique to
that DXCC entity (i.e. PY0F, PY0S, PY0T or VK9W, VK9L, VK9C), then that
prefix (without the slash) is used as the "reference"
prefix.  HK0M is not a unique prefix for Malpelo; in fact, other than HK0TU,
and an HK5/0 that was on a few years ago, I don't know that any other
callsign has been used from there.  HK0 is/was also used from San Andres,
Bajo Nuevo and Seranna Bank.  So that is why the / notation is used.  Same
for VP8s, E5, FO, etc.
