<div>I use GPredict, which leans on
celestrak for TLE's. 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>

I'm trying to track the orbit for PSAT using celestrak TLE
however, can't seem to find him there. Can someone share
where one can find the TLE for PSAT<br>

this is a fantastic milestone in the APRS technology wave;

I currently have an Icom AH-7000 discone monitoring 145.825
for the ISS digipeter running 24/7.<br>
<div><br>
</div>
Go to <a class="moz-txt-link-rfc2396E" href="http://WA8LMF.net/map" target="_blank"><http://WA8LMF.net/map></a> and follow the links
there.<br>
<div><br>
</div>
It appears to be not very effective for high-elevation RX. I
assume the <br>
discone has more of a vertical dipole-like pattern that favors
the horizon rather than over head, perhaps with slightly
fatter lobes than a normal vertical dipole. As I often say,
it's equally poor at all frequencies from<br>
50-1000 MHz.....<br>
<div><br>
</div>
I assume the 3/4-wave vertical, over an adequate ground plane,
would have multiple lobes with one up-tilted substantially,
and would favor high-angle RX better than the discone. Albeit
with still a null at at or near the zenith.<br>
<div><br>
</div>
Any sense how the 3/4-wave compares with the discone?<br>
<div><br>
</div>
I am considering building a Lindenblad antenna (four 1/2-wave
dipoles arranged in a horizontal square with each one tilted
about 30 degrees from horizontal) that supposedly creates a
nearly hemispherical pattern that is circularly polarized at
the zenith. Apparently the FAA uses these to communicate with
aircraft anywhere from the horizon to directly overhead.<br>
<div><br>
</div>
Anyone have experience with the Lindenblad for satellite
downlinks on 2M? How <br>
does it compare with the other two above?<br>
<div><br>
