Re: DX View Distances


 

re "When presented with a callsign (scenario #1 above), DXView does not
currently perform a callbook lookup or inspect previously logged QSOs with a
specified callsign in order to determine a more accurate location."

However, if you type a callsign into DXKeeper's Capture window and strike
the Enter key, then DXKeeper will inspect previous QSOs (if enabled),
perform a callbook lookup (if enabled), and direct DXView to select that
station's location. In determining the station's location, DXKeeper gives
information extracted from logged QSOs precedence over information obtained
by callbook lookup, and gives information extracted from more recent logged
QSOs precedence over information extracted from less recent logged QSOs.

Hi.
Apologies if this has been covered or answered before but I'm a newbie
to this program.

Could anyone tell me what use the Latitude/Longitude, Distance and Grid
values are in DXView?

DXView lets you select a "location" by
1. typing a prefix fragment or callsign into DXView's Main window; this
selects a location based on prefix and callsign analysis

1a. if the callsign was issued by the US Federal Communications Commission
(FCC) and the USAP database is installed, the location is the center of the
zip code registered as the station location with the FCC

1b. if the station's country unambiguously associates call areas with
geographic regions, a representative location within the callsign's region
will be selected (e.g. Russia, Japan)

1c. otherwise, a representative location within the callsign's country will
be selected


2. clicking on a QSO in DXKeeper's Log Page Display; if the QSO specifies a
grid square then its location will be selected, otherwise callsign analysis
will be used to select a location as described in 1 above


3. double-clicking an entry in SpotCollector's Spot Database Display; if the
entry specifies a grid square then its location will be selected, otherwise
callsign analysis will be used to select a location as described in 1 above


4. specifying an IOTA tag (if the IOTA database is installed)


5. specifying a latitude and longitude


5. specifying a grid square


6. clicking on a location in DXView's world map


The primary uses of a selected location are to
a. aim a directional HF antenna (including the determination of whether
short-path or long-path propagation is more likely)

b. assess the signal path's likely interaction with the auroral zone, the
position of which is estimated based on the K-index provided by
SpotCollector

c. generate an HF propagation forecast using PropView


When presented with a callsign (scenario #1 above), DXView does not
currently perform a callbook lookup or inspect previously logged QSOs with a
specified callsign in order to determine a more accurate location.
