Launched on 20 May. See <a id="yui_3_16_0_1_1433302799723_4319" rel="nofollow" target="_blank" href="http://aprs.org/psat.html">http://aprs.org/psat.html</a></span></div><div id="yui_3_16_0_1_1433302799723_4320" class="yiv5260960677MsoNormal"><span style="color:#1f497d;"> </span></div><div id="yui_3_16_0_1_1433302799723_4324" class="yiv5260960677MsoNormal"><span id="yui_3_16_0_1_1433302799723_4323" style="color:#1f497d;">What we need is more IGates bringing the downlink into the APRS-IS. So, if you have a spare radio and can run another IGate instance, we invite you to tune it to 145.825. The satellite signal is weak with only 350 mW, but when it is over your station, it is 10 dB stronger than on the horizon. A good OSCAR class station has no problems…</span></div><div id="yui_3_16_0_1_1433302799723_4325" class="yiv5260960677MsoNormal"><span style="color:#1f497d;"> </span></div><div id="yui_3_16_0_1_1433302799723_4327" class="yiv5260960677MsoNormal"><span id="yui_3_16_0_1_1433302799723_4326" style="color:#1f497d;">I don’t expect anyone to wear out their rotators tracking PSAT, no, just a simple vertical over a ground plane will do. Either a 19” vertical whip over a large 6 foot square ground plane or even better, a 58” vertical monopole over the ground plane. This ¾ wavelength vertical has almost 7 dBi gain and will pick up signals during the few minutes overhead. If we have enough of these simple omni monitoring stations/igates then the fact that they only receive near overhead is made up for by the larger number of such simple stations.</span></div><div class="yiv5260960677MsoNormal"><span style="color:#1f497d;"> </span></div><div class="yiv5260960677MsoNormal"><span style="color:#1f497d;">The larger ground plane (as large as possible) gets closer to the theoretical 3 dB gain of a reflector.</span></div><div class="yiv5260960677MsoNormal"><span style="color:#1f497d;"> </span></div><div class="yiv5260960677MsoNormal"><span style="color:#1f497d;">Bob, WB4aPR</span></div><div class="yiv5260960677MsoNormal"><span style="color:#1f497d;"> </span></div><div><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0in 0in 0in;"><div class="yiv5260960677MsoNormal"><b><span style="font-size:10.0pt;">From:</span></b><span style="font-size:10.0pt;"> Robert Bruninga [mailto:<a rel="nofollow" ymailto="mailto:bruninga@usna.edu" target="_blank" href="mailto:bruninga@usna.edu">bruninga@usna.edu</a>] <br><b>Sent:</b> Monday, June 01, 2015 9:19 AM<br><b>To:</b> <a rel="nofollow" ymailto="mailto:amsat-bb@amsat.org" target="_blank" href="mailto:amsat-bb@amsat.org">amsat-bb@amsat.org</a><br><b>Cc:</b> <a rel="nofollow" ymailto="mailto:bruninga@usna.edu" target="_blank" href="mailto:bruninga@usna.edu">bruninga@usna.edu</a><br><b>Subject:</b> PSAT digipeater is ON</span></div></div></div><div class="yiv5260960677MsoNormal"> </div><div class="yiv5260960677MsoNormal">I just turned on the PSAT digipeater.
