What's new

The latest releases, from each tool's own release notes.

  1. Coverage Predictor v1.61.2 Path profile opens in the same corner window as the Ruler, and its elevation axis now reads the right way up.
  2. Link Planner v1.5.15 The Ruler opens in a window in the corner of the map, like the Sites window, with the distance and bearing between the two sites.
  3. ACMA Database Map v1.6.3 A full review of the tool: LM 08 distances by band, corrected link physics, safer paid reports and faster search.
  4. RF EME Exposure Modeller v1.4.8 A blank or missing input no longer passes or crashes the tool, results stay current after an edit, and the report names the standard it was computed against. Method 1.4.5: valid ARPANSA, ICNIRP and IEEE scenes compute exactly as before.
  5. HF Link Planner v1.4.2 Predictions change. The field strength now follows ITU-R P.533-14 as printed in four more places: the excess loss Lz, the reflection height each mode's field is built on, the takeoff angle each antenna gain is read at, and the method used beyond 7000 km, which the LUF now uses too. Storm risk drops a storm MUF factor that is in no ITU-R document. The engine is now version 2.20.0, so saved coverage maps show as made by an older engine until you recompute them.
  6. BESS & Solar System Designer v2.8.0 Cable sizing, battery autonomy and the compliance summary are stricter and more honest. Re-run saved designs: some cables step up a size and some autonomy checks now fail.

How the tools connect

Real data under the tools

10 tools read the national licence register, refreshed every day, and 19 draw on the component catalogue's 55,000+ real parts, so a design starts from what is on air and from equipment you can actually buy.
