I have never seen this on any other mailing list.
Is it because the mailing list configuration sets "reply" to be the
user who sent the email and not the list, and then it is easier to
send an email to the list by starting a new thread as opposed to
"reply all" and then having to edit out all the email addresses except
amsat-bb?
If the information in the emails to this list is helpful to others who
search google and find it in the archives, it will be harder to find
if it's across multiple threads.
Additionally, not keeping things in thread makes it harder to follow a
conversation and more difficult to manage email. If I am not
interested in a particular thread I can just mark the whole thread
read as opposed to two or three other threads.
If a reply to an original thread is truly a different subject then it
is common practice to change the subject like so:
How do I search the archives? (was: Why do people start new threads
when replying to a post on amsat-bb?)

I looked into the Toshiba Module solution mentioned, and it is a pretty
decent solution, but my problem with it was filtering. Those modules
are great but have pretty bad third harmonic and spur rejection. This
means that final stage filtering will be required to stay within FCC
limits (I think -60 dBc is the requirement, can't remember off the top
of my head). The W6PQL reference is fantastic and is closer to a good
solution because he has the filtering problem solved in his designs (you
may have to get the filter board separate for the 70cm design, I think
he includes a filter in the 80W 2m Amp design). For the budget
conscious, this is the path I would recommend. I would probably look
into using the Toshiba modules with lower output power (single digit
Watts) as a driver for something like a Mirage Amp (that I think has the
final stage filtering built in).
====snip
The W6PQL board is wide-band and one only needs to use proper value
bypass capacitors and wind coils for 435-MHz. Not saying that is
trivial but that is all that would be needed for filtering using that
pc board. In the past others made generic pc boards for using the
Toshiba modules. This is going to require some engineering to
accomplish or you can spend big bucks and go the Kuhne Engineering route.
I assume anyone using the Ettus B210 is willing to do that.

So let's give this a try. I did a reply to all from gmail and it is
sending both to you directly and also to the bb.
I seldom have this problem, but I suspect 2 or three variants of reasons:
1) The mail client you use employs something other than the subject to
group conversations.
2) The mail client someone else uses does not keep the thread number
3) The most likely may be that they get a digest and start a new mail
message rather than making the other common mistake of quoting the entire
digest.
My ideas anyway. See if mine comes in the same conversation for you...

John,
The main problem that I have seen with threads is that some people are
just utterly unaware of the existence of threads. I have seem people
even "recycling" threads that happen to have the right addressees in
them. So pressing reply all and then changing the subject.
They are just blissfully unaware of how that is displayed on E-mail
clients post 1990.
One other thing that happens to me a lot: people who are asking me a
question in a thread with a completely unrelated subject. Often, I
have just deleted the thread, because that's what I do. If the message
is not about the subject, chances are that I have just deleted it.
Example: someone asking a technical question in a thread that has
subject "activation of grid XYZ" wil not be seen by me, because I do
not care about grids and delete all email with subjects related to
grids.
Nothing against sending grid emails though, just to be sure that I
don't upset someone.
Anyway, you may be attempting to herd coconuts, but maybe someone will
take notice.

This is a legitimate reason:
3) The most likely may be that they get a digest and start a new mail
message rather than making the other common mistake of quoting the
entire digest.
There is no easy way around this, but it is helpful to try and use the
same exact subject by copying and pasting.
It's not on my end, most emails are threaded fine.
Anyway, as someone has said off list, this is not likely to change
everyone's behavior. It's just a slight pet peeve.

Was looking with a chary eye at the Mitsubishi boards available on the
net. Pulled the trigger on 4 boards and 2 amp controllers from 'pql.
Spent many, many nights browsing his homepages.
Need to decide which part I should mount.
