Specifications

The Prefix table
This table keeps all prefix combinations and associations (2800 entries)... The Prefix table
includes the following fields Prefix - DXCC - Longitude - Latitude - Continent - CQ Zone
- ITU Zone - Territory . This table allows you to associate a given prefix with a DXCC
country and any of these geographical data.
Notes
Warning: you must use a reference to an existing DXCC prefix of the DXCC table.
Example: you may associate VK0IR to VK0/H (DXCC = Heard Island) or distinguish latitude and
longitude between W2 and W6… < /P>
Advanced: You may also define special callsigns from the Prefix table by adding the sign - to the
Prefix (i.e. K5D-). TRX-Manager searches for a strict match with this particular callsign before
browsing the prefix database. However, a recommended alternative is to create an entry in the
special callsigns database (see above).
The DXCC table
You do not have to edit this table except when a change is made by the ARRL in the DXCC
country list. In this case, it is recommended to wait for a program update… You may wish to
edit this table to make the change yourself in the DXCC country list. This table includes a
DXCC field (or index), the DXCC country name and the ARRL code (or ADIF code).
Loading a customized prefix database
According to your needs, you may prefer using your own customized database while keeping
the original Prefix.mdb. This is possible by opening an other Prefix database (it must exist)
from the Preferences/Logbook tab.
