[Dxbase] Prefix mappings

Tue Nov 29 22:03:11 EST 2005

Ed,
Going backwards a bit to find out something about those
callsigns - it appears that they were added in for DXbase2005
.. The recommendation for any DXbase 2005/2006 user would be:
Update your Call Map TAB as follows:
Callsign Prefix Old1PFX Old1Date
AC0H K A5 19760101
AC1H K A5 19760101
AC6H K A5 19760101
AC7A K A5 19760101
AC7H K A5 19760101
AC8H K A5 19760101

Since the WW contest was CW and the SS contest was SSB, I was confused. Certainly I had KL7, KH6, KP2, KP3, etc. already, after having several years of sweeps. I ran Joe's report that told me new band-mode countries worked in a contest. It told me that on 20M SSB, I had worked a new country A5, from a QSO with AC0H. Huh? Checking the prefix mapping, I saw the following entry:
>> MAP PFX: AC Pri PFX: K OLD1 PFX: A5 Old1 Date: 31-12-1971
> MAP PFX: AC0 Pri PFX: K 
>> Why did it map this AC0 call worked in 2005 to an A5 prefix? Was the alias list busted? No, so I checked the call map. There it was. AC0H mapped to A5. So was AC1H, AC5H, AC6H, AC7A, AC7H, and AC8H. I checked these calls in QRZ and they are valid US calls.
