In addition to its own archives, amsat-bb used to be archived at
mail-archive.com here:

For whatever reason, that seems to have stopped in 2014. If we could get
that restarted, that would be useful, since it has a pretty good Advanced
Search capability.

No, the problem is that those native mailman archives, while complete, are
not searchable.
The mail-archive.com archives have a proper Advanced Search option. That's
pretty much why mail-archive.com exists. It would be easy to get amsat-bb
added again, but I don't know if there's a reason they were stopped in 2014.

Brad,
Good find. Though Bob wants a dual band filter with 1 in/1 out. I wonder if
those might be able to be combined some way.
I will definitely save the article. Thanks.

Hello Bob,
In these parts, North Texas Microwave Society (https://www.ntms.org/) is
a gathering of microwave enthusiasts. I'm a relative newcomer to this
group, but there are a lot of good articles and presentations on the
website.
W1GHZ (http://www.w1ghz.org/) has a site chock-full of various microwave
projects, ideas, and publications.
The RTL-SDR folks have an entire category dedicated to microwave
projects and links, but it is not all amateur radio.
https://www.rtl-sdr.com/tag/microwave/
These sites just scratch the surface of microwave work. I'm sure there
are many on the -bb list that could provide other pointers.

Hawkeye 360, a company I cofounded, has its next cluster of 3 spacecraft
through testing. It has significant new capabilities. And there are FIVE
more clusters planned for launch in 2021.
This candidate for the board of directors of AMSAT brings experience and
capabilities that can help AMSAT.
I ask for your vote and if you can find a more qualified candidate vote for
them.

Good luck, Bob!? 'great to have your willingness, experience, contacts, and
energy!
Ev, W2EV
PS: Remember the thread about finding people with a "6-degrees of
separation" from resources that could be helpful to getting amateur radio
payloads into HEO?? Yeah, the one that somehow got so heated that a
moderator asked that it be ended?? It seems that the nay-sayers have some
rethinking to do.? Lol.

Fantastic about the launches Bob, with the next cluster is there any
possibility that they could include amateur radio payloads?

Folks,
I am an AMSAT life member and very much want to participate in the upcoming
election of directors. I have been watching the mail for a ballot envelope
from AMSAT and have yet to see one.
Were the ballot envelopes mailed out all at once or are they being sent
"batched"? When should I start to worry? Thanks much in advance for your
answer.

Content-Type: text/plain; charset=utf-8; format=flowed
Hello all,
In order to evaluate antenna effectiveness in the 70cm downlink band,
I'm trying to visualize the orbits of the following satellites:
AO-27
SO-50
RS-44
I can find the perigee/apogee and output power on these, and, so far, I
have:
AO-27 788x801 km 1W/0.5W/0.1W
SO-50 603x713 km 0.25W
RS-44 1175x1511 km 5W
On the FM birds: My observed data shows that SO-50 is difficult to hear
while AO-27 is booming, so I hypothesize that AO-27 is transmitting with
0.5W or 1W.
RS-44's beacon seems to be fairly weak, while CW/SSB signals on the
transponder are quite strong.
Does anyone know where I might find more details on RS-44's construction
such as antennas and power output for the beacon?
Thanks,
--- Zach

I couldn't find any tech specs other than what you have, but I did find a

Also consider using Lilacsat-2 for your comparison. It has a circularly

I founded Federated Wireless with Dr. Joseph Mitola (father of SDR and
Cognitive Radio), Dr. Charles Clancy (VP for Intelligence MITRE), and Dr.
Jeffrey Reed of Virginia Tech. The patents I am assigned and the ideas I
helped with enable Spectrum Sharing now approved by the FCC. Verizon is our
largest customer. I am a candidate for the AMSAT board of directors. If you
find someone more qualified, vote for them.
