Patrick and Lizeth,
Thank you both very much. I appreciate the suggestions, and I guess I will
just plan on buying a FCD Pro+ this Friday.
I will say that I am enjoying the RTL-SDR for some other non-satellite
projects. It is great for monitoring my local repeaters and listening to
the commercial stations in my area, so it is certainly not a complete loss,
and even if it was it was only ~$20.
I have not been able to get HDSDR to work with the dongle, though, but I
was able to add the plugin to SDR# to interface with SATPC32 last night.
Perhaps I will have better luck with the FCD Pro+.
In the end the FCD Pro+ is probably something I will use with some other
radio projects on HF, so I am sure that I will get plenty of use out of it
no matter what, but I am excited to find out all of the satellite uses I
will have for it.
Thank you again for the information. I'll catch you guys on the linear
satellites in the near future.

W1AW/7 will be on FO-29 for the western pass at 0200 UTC,
followed by AO-73 passes at 0400 and 0534 UTC. It looks like
Hawaii should be in the footprint for a few minutes, starting
around 0204 UTC, if anyone out there is interested in getting
I plan on having W1AW/7 on the air Monday afternoon from the
DM33/DM43 grid boundary for the 1845 and 2027 UTC passes.
The earlier pass around 1705-1713 UTC has maximum elevation
of only 4 degrees, not really a workable pass from the Phoenix
area with the mountains around the city, so I will focus on the
two later passes. After these passes from the grid boundary,
W1AW/7 will be on FO-29 and AO-73 passes in the late afternoon
and early evening to wrap up the W1AW/7 satellite activity from
Arizona as part of the ARRL Centennial QSO Party.
As a reminder, QSL cards for all W1AW/x operations will be handled
by the ARRL. As ARRL receives logs from the W1AW/x operations,
those logs are uploaded to Logbook of the World - including the grid
locator(s) for each QSO. QSOs with W1AW/7 on the AO-73 passes
tonight and tomorrow night also count for N8HM's new 73 on 73 award,
if you are looking to get unique calls in your log.
