PSA: it's 2011, not 1971. The plaintext filter on l-w is stupid. If
its main goal is to ensure that patches come through correctly, it
doesn't help that much. Independent of plaintext, people still have to
jump through hoops to make sure the line wrapping comes through okay.

See below mail.

Are you forgetting to account for the 3 dBi--7 dBi antenna gain?
