Dear all
I would like to know if there is a mirror of the pages located at the USNA
web server specifically the
PCsat WEB page http://www.ew.usna.edu/~bruninga/pcsat.html
ISS-APRS FAQ: http://www.ew.usna.edu/~bruninga/iss-faq.html
CUBESAT Designs http://www.ew.usna.edu/~bruninga/cubesat.html
APRS LIVE pages http://www.ew.usna.edu/~bruninga/aprs.html
APRS SATELLITES http://www.ew.usna.edu/~bruninga/astars.html
I found that the server may have a firewall not allowing connections from
Brazil.
Yours

Bruce, N7RR sent me this email via APRS and so I have no way to respond
but here:
>How [do you] set [the] D7 [to] 145.827 for [PCSAT]? 73 Bruce
Doppler is +/- 3 KHZ, so set to 145.830 at first part of pass and then
shift to 145.825 towards the end. The highest rate of change is in the
middle, so you hardly miss anything during the transistion. Or just set
145.825 permanently and it will work just fine...
The bandwidth of an FM signal is 15 KHz and so having the center off by 2
KHz makes little difference. We purposefully lowered the deviation to
minimize any problems of doppler or small offsets.

I have been using a hacked (see http://www.radiohound.com/randgps.htm) Rand
McNally Palm III GPS connected to my TM-D700A in my truck for a few weeks
now. Just recently I noticed that my posits are wandering. See
http://www2.findu.com/cgi-bin/breadcrumb.cgi?call=kd7qhx-1&start=100=00.
According to FindU my truck is currently in North Platte, NE. Yesterday I
watched it go from Montana in the morning to the Caspian Sea in Russia at
lunch time to the Bahamas in the evening to Glendale, AZ by nightfall.
Has anyone else experienced problems with this combination? I find that
power cycling the GPS will bring it back to reality for awhile but after a
few hours it wanders off again... Anyone have suggestions on what to do
with it?
