SITES.DAT Site database

SITES.DAT contains locations of many high spots and the QTHs of many microwave operators This was originally started a very long time ago (by G3YGF and others in the BBC computer days) and I put together this version around 1990 to go with the original DOS based height database software. Subsequently Mike G0MJW took the site database and incorporated it into his path plotting software while keeping the original format. By which route I found I'd got it back, although it appears to have done the rounds as several more sites had been added.

I've now taken that version, cleaned up the GB3 Beacons listing a bit, deleted several SK's and placed it here SitecalcWin.zip along with a utility for reading it and performing all the calculations needed with NGRs or Locators or Lat/long

By now there are many obsolete sites / QTHs, SK's I've missed and other errors. So it is long overdue for an overhaul. Can I ask you to check your entry and any others of note and email me any changes to be made, and most important, deletions that are needed. All direct to me at andy.g4jnt[at]gmail.com
In particular, for any site / QTH with only a six digit locator could you supply either NGR or 8 digit locator. The 6 digit ones really aren't good enough for accurate dish pointing at 10GHz and up on medium length paths. THIS PARTICULARLY applies to BEACONS which we often rely on for an accurate bearing reference. The latest version will always be available at that URL as changes come in.

The format is a simple text file (you may need to tell your PC to treat .DAT files as text and open with a suitable text editor)
Each entry consists of a line containing site name followed by a tilde ~ followed by the location. The location can be stored as either a 2 letter plus 6 digit NGR which is the preferred form and accurate to 100m or as a locator. Ideally this will be the 8 digit version (eg. IO90IV58) accurate to around 450m. While there are many 6 digit locators stored their 4.5km accuracy is not really good enough for bearing determination, and certainly no good when used with path profile and height plotting software.

SitecalcWin.zip
Distance / Bearing calculator, generate listing. Combines the functionality of SITECALC, LOCATION and GETSITE from the old DOS software. Uses SITES.DAT

G0MJW Path Profile software

And now for something completely different - Postcode Lookup
This utility allows you to enter a postcode and if it is stored in the database, will generate an approximate locator and NGR. This will be accurate for urban areas, but less so for rural ones.
The download is quite large at 28Meg. Unzip both files to one folder. Run FindPcode.exe and insert the full path and filename where PCODES.TXT can be found. This will be stored for future use.
