I don't think I can/should manually enter TLE's into that program. They might get wiped out with the next network TLE refresh -- or go stale otherwise. If the PSAT TLE's aren't yet part of the celestrak feed, is there a web site out there (e.g. ariss.net, aprs.fi, etc.) providing PSAT tracking? Would also be nice to see some web-based tracking integration with openstreetmap.org -- it's becoming quite polished lately. If time permitted, I'd tinker with that myself.<br></div><div aria-label="Compose body"><br></div><div aria-label="Compose body">My igates don't yet run 24x7, but I'd like to see whether my setups can hear it for passes when I'm able to tinker in the shack.<br></div><div aria-label="Compose body"><br></div><div aria-label="Compose body">73, KD0KZE / Paul<br></div><div><br></div><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;" data-mce-style="color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><b>From: </b>"Nagi Punyamurthula via aprssig" <aprssig@tapr.org><br><b>To: </b>"Stephen H.
