I wasn't thinking of amateur frequencies, >but my fingers sometimes have a mind of their own ;) Interestingly enough, my primary objection was NOT really commercial encroachment on an existing amateur structure (though that is an important consideration!); rather, it was the fact that because we're talking really short-range communication (way less than a kilometer, in most cases) using frequencies below a gigahertz would be a counter-productive shame. Here, we WANT "line of sight"!

I get a free (bingo-card) magazine industry magazine called "Microwaves and RF," which is sort of the EDN for the high-frequency communication crowd. You'd be amazed at the level of technical (chip) development there. Chip sets that do frequency synthesis/full RF/IF on surface mount chips. Jim Bell, N7IJS (BTW, I use Eudora, and I have PGP.

With a tightly focused beam (light is easy, I don't know about lower frequencies), you can prevent interception except by very obvious physical devices. (e.g. Someone in a cherry picker truck.)

Windows Eudora and PGP

It is not as easy as I would like. You have a couple of options: 1) Use cut-and-paste into Private Idaho. Private Idaho will allow you to paste back into Eudora. (Or you can send out from Private Idaho directly.) This option is useful becuase it supports nyms and chaining of remailers. 2) Get one of the standard Windows PGP shells and paste into that. After signing, you will have to repaste into Eudora again. These seem to be the only options. I am not certain if there is a standard DDE or OLE interface that could be used to feed message information back and forth between Eudora and some other app. There have been a number of promises of Eudora/PGP integration, but nothing has materialized yet. There are no easy answers I know of... If you need a copy of Private Idaho, I can point you to a web site or bring a copy along to the meeting on the 20th.

What are the legal risks of writing (and releasing) a remailer, and what steps can an author go to to minimise any unwanted (legal or civil) attention ? ob.

What to do about Germany
by Michael C. Peponis 17 Dec '03

17 Dec '03

What the German goverement threatned to do was inexcusable, but something can be done about it. The way that mail and postings are handeld, it is possible to trash mail and posting coming or going to a certin destination. This is censorship, but maybe the members of the goverment have justified such an action. If they can censor others, should others not be able to censor them? That's one of the beauties of the electronic age, the only thing that matters is intelligence, numbers or political power have negligable effects. Are the german authorities worthy of such an reaction? Have they crossed the line? If they have, maybe they can serve as the example of what happens when a group of people attempt to force their will on others. Regards, Michael Peponis PGP Key Avalible form MIT Key Server

There are several vendors offering 2.4GHz wireless with ranges up to 20 miles. Though the 900MHz stuff is much cheaper. Unless you have a pager cell on your roof, 900MHz should serve you fine. >I get a free (bingo-card) magazine industry magazine called "Microwaves and >RF," which is sort of the EDN for the high-frequency communication crowd. >You'd be amazed at the level of technical (chip) development there. Chip >sets that do frequency synthesis/full RF/IF on surface mount chips. If you don't want to build your own, there are various vendors that use the NEC 900MHz bridge card in their products. Or just buy the card, get an old 486, and round up the software from somone. >(BTW, I use Eudora, and I have PGP. Could somebody explain how to PGP-sign >messages, ideally EASILY?)

That's assuming the phoneco cooperates. Punknet is a 'Guerilla ISP'. Twenty of us share a 128k ISDN line, distributed via high-speed modems. It's been running fine for over a year now, but Pacific Bell has evidently decided to get rid of us. How? Simply by refusing to either repair or replace our 25 pair trunk line, which is rapidly degrading. We've offered to replace it ourselves, but according to them, it's illegal. Right now, we've got three dead lines, and two others that only will do 1200 baud. We've been told that what they're doing is probably illegal, but it's the old problem: Where does an 800 lb. gorilla sleep? We're fighting this like all hell, but who knows?
