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.

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><span style="font-family:"helveticaneue","serif";color:black"></span></p></div><div><p class="MsoNormal" style="background:white"><span style="font-family:"helveticaneue","serif";color:#1f497d"> </span><span style="font-family:"helveticaneue","serif";color:black"></span></p></div><div><p class="MsoNormal" style="background:white"><span style="font-family:"helveticaneue","serif";color:#1f497d">The larger ground plane (as large as possible) gets closer to the theoretical 3 dB gain of a reflector.</span><span style="font-family:"helveticaneue","serif";color:black"></span></p></div><div><p class="MsoNormal" style="background:white"><span style="font-family:"helveticaneue","serif";color:#1f497d"> </span><span style="font-family:"helveticaneue","serif";color:black"></span></p></div><div><p class="MsoNormal" style="background:white"><span style="font-family:"helveticaneue","serif";color:#1f497d">Bob, WB4aPR</span><span style="font-family:"helveticaneue","serif";color:black"></span></p></div><div><p class="MsoNormal" style="background:white"><span style="font-family:"helveticaneue","serif";color:#1f497d"> </span><span style="font-family:"helveticaneue","serif";color:black"></span></p></div><div><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0in 0in 0in"><div><p class="MsoNormal" style="background:white"><b><span style="font-size:10.0pt;font-family:"helveticaneue","serif";color:black">From:</span></b><span style="font-size:10.0pt;font-family:"helveticaneue","serif";color:black"> Robert Bruninga [mailto:<a href="mailto:bruninga@usna.edu" target="_blank">bruninga@usna.edu</a>] <br><b>Sent:</b> Monday, June 01, 2015 9:19 AM<br><b>To:</b> <a href="mailto:amsat-bb@amsat.org" target="_blank">amsat-bb@amsat.org</a><br><b>Cc:</b> <a href="mailto:bruninga@usna.edu" target="_blank">bruninga@usna.edu</a><br><b>Subject:</b> PSAT digipeater is ON</span><span style="font-family:"helveticaneue","serif";color:black"></span></p></div></div></div><div><p class="MsoNormal" style="background:white"><span style="font-family:"helveticaneue","serif";color:black"> </span></p></div><div><p class="MsoNormal" style="background:white"><span style="font-family:"helveticaneue","serif";color:black">I just turned on the PSAT digipeater.
