I also stumbled across the Museum Ships booth and chatted nostalgically about the origins of APRS back in 1983 when I first hooked up an Apple-II to the Navy’s NTDS to display hostile and friendly surface, aircraft and undersea symbology.</p>
<p class="MsoNormal"> </p><p class="MsoNormal">I have always felt that EVERY museum ship should have APRS displays in the radio rooms and CIC to entertain the visitors.</p><p class="MsoNormal"> </p><p class="MsoNormal">In a moment of levity, I thought about adding Submarines, and Torpedos and Hostile aircraft and missiles to the symbol set for playing wargames on museum ship weekend…. Then realized that the Aircraft symbol set should have many more too. So I ended up making these changes:</p>
<p class="MsoNormal"> </p><p class="MsoNormal">AIRCRAFT</p><p class="MsoNormal">/^ = LARGE Aircraft</p><p class="MsoNormal">\^ = top-view originally intended to point in direction of flight</p><p class="MsoNormal">D^ = Drone</p>
<p class="MsoNormal">E^ = Enemy aircraft (too bad I cant use the original Hostile)</p><p class="MsoNormal">/g = was glider and \g was Gale. We should re-use these and</p><p class="MsoNormal">Gg = let this be Glider</p><p class="MsoNormal">
H^ = Hovercraft (new may 2014)</p><p class="MsoNormal">J^ = JET (new may 2014)</p><p class="MsoNormal">M^ = Missile (new may 2014)</p><p class="MsoNormal">\O = was made a Rocket in 2004, but that destroys overlayed balloons</p>
<p class="MsoNormal">R^ = ROCKET is now the preferred approach (new may 2014)</p><p class="MsoNormal">V^ = Vertical takeoff (new may 2014)</p><p class="MsoNormal"> </p><p class="MsoNormal">SHIPS: #s</p><p class="MsoNormal">
/s = Power boat (ship) side view</p><p class="MsoNormal">\s = Overlay Boat (Top view)</p><p class="MsoNormal">Cs = receive as Canoe but still transmit canoe as /C</p><p class="MsoNormal">Js = Jet Ski</p><p class="MsoNormal">
Ks = Kayak</p><p class="MsoNormal">Hs = Hovercraft (new may 2014)</p><p class="MsoNormal">Ts = Torpedo (new may 2014)</p><p class="MsoNormal">Us = sUbmarine U-boat (new may 2014)</p><p class="MsoNormal"> </p><p class="MsoNormal">
As usual, the <a href="http://aprs.org/symbols.html">http://aprs.org/symbols.html</a> web page has been updated.</p><p class="MsoNormal">I suggest that any use of symbols for EXERCISEs include the word EXERCISE as the first word in the object text.</p>
