- Ref AO-13:
-
- I found out today that "nobody likes the Cushcraft satellite antennas".
- Is this a fact or just an opinion?
- I wonder what is the "better" antenna combination for 144/430? Is the KLM
- that great?
- I have an Cushcraft R7 and a Mosley CL 33 that I use for
- HF right now. I have used Cushcraft antennas for six and VHF before with
- no particular problems. Is there a problem with the AOP-1 or what?

- Subject: Portable AO-13 operation
- To: ham-space@ucsd.edu
-
- Looks like Mode S is the way to go for most
- portable station that can work well through
- AO-13. Maybe that is why they have Mode B
- receiving contests--takes a lot more work to
- hear the transponder noise floor....
-
- As I thought, as confirmed by G3RUH in a
- recent published letter, the beacon uses
- *all* the transponder power, thus you
- want to be *weaker* than the beacon.
- During a busy pass, I guess this means you
- want your signal to be at least 6 dB
- weaker, to accomodate at least 4 users.
-
- My 2 foot dish for for 2.4 GHz receive
- is probably too big, I'll be trying a
- small helix with a 0.4 dB system NF converter
- when (if?) the weather gets nice outside.
-
- Wonder if anyone has gotten the HP PHEMT
- to work well on this band? The data sheet
- says a device NF of 0.13, but given the
- error inherant in such a measurement, it
- might be no better than other PHEMTs. I'll
- be bringing something to the West Coast
- VHF conference for comparison.

- The most current orbital elements from the NORAD two-line element sets are
- carried on the Celestial BBS, (513) *253-9767*, and are updated daily (when
- possible). Documentation and tracking software are also available on this
- system. As a service to the satellite user community, the most current
- elements for the current shuttle mission are provided below. The Celestial
- BBS may be accessed 24 hours/day at 300, 1200, 2400, 4800, or 9600 bps using
- 8 data bits, 1 stop bit, no parity.
-
- Element sets (also updated daily), shuttle elements, and some documentation
- and software are also available via anonymous ftp from archive.afit.af.mil
