Locked What's the use of grids in FT8.


Amos Sobel 4X4MF
 

I did try hard to find a cluster application which can locate an active  station according to it's grid. None was found.
I did try DX Spider but it is too complex to install under Win10.
Can anybody recommend one?
If none is found then what's the use of grids in FT8?

Amos,

are you serious?

On VHF and up grids are useful for determining beam headings.

Many ops chase grid square and grid field awards and certificates.

Many contests use grids as multipliers.

Many contests use distance calculated from gridsquares for points.

EME operators require the DX station gridsquare to calculate Doppler frequency shifts.

OTOH the DX Cluster network has no field for gridsquare in the spot message format passed between nodes, so gridsquares are a very loosely managed piece of data in that domain. Usually managed by each cluster node keeping a local table mapping calls to grids AFAIK.

Plugging the received gridsquare into WSJT-X will yield a distance and beam heading. DXAtlas can display a map with grid squares as an overlay, and can also provide distance and beam heading. These are two that I use regularly. I'm sure there are others.

If you're using Linux you can use GridTracker, it automatically logs to several logging options (including LoTW and eQSL) and will show you where on the map your making a contact with.  It connects to the UDP server of WSJT-X.

Hi Timothy,

thanks for that. Just a small technical correction. WSJT-X is a UDP client for the WSJT-X UDP Message Protocol, it is the interoperating third-party applications, like GridTracker, that are the servers in this relationship.

Got it, thanks for letting me know that!  I'm a developer myself, so I should know these things!

Hi Timothy,

no problem, it can be a bit vague which is client and server with UDP, the key here is that there can be multiple clients (multiple WSJT-X instances) talking to one server. Here the clients need to know the server address and service port and the server listens for traffic there.

Hi Timothy.

GridTracker also runs on Windows.
