Re: Satellites Over US West Coast
OK now I'm getting somewhere! My SatPC32 predictions DO NOT match the info on the AMSAT link below!
My location appears to be entered correctly into the tracking program, the PC clock is correct and the keps are updated against the 'nasa.all' source.
AMSAT shows next FO-29 pass as 22:41:15 - 23:01:29
My SatPC32 shows FO-29 pass as 22:24:00 - 22:33:00
No wonder I don't hear anything! Now...what could be wrong in my SatPC32 setup to cause this?

Can you hear the beacon on FO-29? You also might have to adjust the uplink frequency in he CAT menu in SatPC32 to find your signal.
Do your SatPC32 predictions match the ones from the AMSAT online prediction?

i'd be happy to be on one of the passes to listen for you or transmit.

I agree with the Amsat times for the next pass over west coast. Get a free copy of Orbitron.

Paul,
for each entry in the listbox (amateur.txt, geo.txt ...) highlight the entry and click "Update Keps" separately.

Paul,
There are really only three possibilities. Your QTH, your Keps, or your system clock. Fortunately, it is easy to find the culprit.
On the AMSAT predict page, select pass prediction, and then near the top of the table, "View current location of FO-29." That will bring up a real time map. Look at both maps, and make certain your QTH is correctly displayed on both.
Next, compare the AMSAT page position of the satellite with the real time SATPC32 prediction. (Both give the Sub-Satellite Points numerically, but use different conventions.) The maps are sufficiently different you may need to wait until the satellite passes some readily identifiable point such as a coastline to compare. (Even if your QTH is wrong on one of the programs, the current position should be correct. If not, then your system clock or Keps are suspect.)
If the QTH is good but the current satellite position is not, then on the main SATPC32 page open the Satellites menu, and then check the Source Files in the left window. Make certain it is NASA.ALL and look at the very bottom where it will give you the date File Date. It should be today if you updated it. It is entirely possible to have a different source file than NASA.ALL selected. If it is an old one, then you will see an error. Right now, FO-29 agrees exactly on SATPC32, the AMSAT tracking page, and another program I use. (The are other issues which apply only to the ISS, but are not a factor on FO-29 since it is "well behaved.")
There are some more obscure possibilities, but knowing the result of your tests should allow us to narrow down the possibilities.
73s,
Alan WA4SCA
