Well, I don't want this to devolve into an OT issue but it is well
established that any feedline loss ahead of the receiver adds to the
total noise figure of the system. (outside influences such as sky
temperature, local noise sources, etc notwithstanding)
So if you place a preamp with a NF of .5 dB at the "rig end" of a
feedline run that exhibits 3 dB of loss at the frequency involved,
you now have an effective noise figure of 3.5 dB ahead of your
receiver. Placing the preamp at the antenna has an obvious advantage
of reducing that NF by 3 dB.

That depends on settings within the email reflector and also on
settings within your email program. And it also depends on whether
you are paying attention when you compose your email. When an email
reflector defaults to "reply to both," I try to remember to delete
the email to the sender and respond only to the reflector. In my
email program (Thunderbird) it's easy to see what's going on in the
address section of the email.

I thought of something later. When you reply to the list does your
email client also send a private message to the person you're replying
to? If so, that would explain why you're getting the message as your
client is sending two messages. I presume the response message is to
enable a white list from real people to the recipient.
