Lansing, MI 48825 > Internet: kjh@usc.edu UUCP: ...!uunet!usc!pollux!kjh > ---------- Sorry, the boundary between near and far field is a function of effective aperture diameter in addition to wavelength. "Reference Data for Engineers" gives the boundary as D squared over lambda, where D is the diameter of the equivalent aperture and lambda is wavelength. For a half-wave dipole, D= .41 wavelengths. For a quarter-wave vertical (over a ground plane) D=.82 and N8DGN's definition is almost right. For a 6 foot C-band TVRO dish, D is about 24 wavelengths. For the 230 foot dish at Goldstone that tracks interplanetary spacecraft at 8.2 GHz., D is 1916 wavelengths, so the far field starts at 4 million wavelengths or 83 miles.

If it was only one ham talking directly to another, that would probably be a factor. But when they start acting as agents or "volunteer carriers" (as opposed to "common carriers") for third parties, it becomes a different ballgame. In that case, we aren't talking about message content; we're talking about whether or not we are allowed to act as agents for third parties REGARDLESS of message content. In that context, the FCC is undoubtedly fully within its mandate from Congress (and the ITU). The bottom line is that we, or rather the bad apples among us, brought this on ourselves. I've been criticized in this newsgroup for being a legalistic vigilante, and yet the so-called "20 meter letter" issue came about because we hams, both severally and individually, have become lax over the last few years in policing ourselves strictly "by the book". It is becoming increasingly obvious with every passing day that the anarchism masquerading as liberal constructionism is damaging our cause. If we don't march in step, it isn't a parade - it's just a bunch of jaywalkers. -- Uucp: ...{gatech,ames,rutgers}!ncar!asuvax!stjhmc!234!1!Jim.Grubs Internet: Jim.Grubs@f1.n234.z1.fidonet.org ------------------------------ Date: 14 Dec 89 17:32:55 GMT From: zaphod.mps.ohio-state.edu!samsung!cg-atla!raybed2!ewb@tut.cis.ohio-state.edu (EUGENE BALINSKI) Subject: DAYTON '90 !! Message-ID: <1422@raybed2.UUCP> DAYTON is comming up soon and will be here faster than you think (APRIL 27, 28, and 29). There was some talk about a USE-NET meeting as well as a calling frequency. This year we should try the same. I would like to nominate 223.60 (dir) as the calling channel as 2 meters is useless. Also, There was some question as to whether a new hotel was going to be constructed on the fleamarket site. Does anyone know if this has happened ? 73 Gene WA1UXA ------------------------------ Date: 14 Dec 89 16:57:44 GMT From: hpda!hpcuhb!hpscdc!rkarlqu@ucbvax.Berkeley.EDU (Rick Karlquist) Subject: electronics parts store - info request Message-ID: <5490079@hpscdc.scd.hp.com> > Can anyone recommend a place in the Menlo Park, Palo Alto, Mountain > View area that sells electronics parts?

This is broadcasting, not an informational bulletin pertaining to amateur radio. No wonder the FCC gets so disgusted with our lack of judgment and self-discipline. -- Uucp: ...{gatech,ames,rutgers}!ncar!asuvax!stjhmc!234!1!Jim.Grubs Internet: Jim.Grubs@f1.n234.z1.fidonet.org ------------------------------ Date: 14 Dec 89 19:27:35 GMT From: hpda!hpcuhb!hp-ses!hpdml93!jmcvey@ucbvax.Berkeley.EDU (John McVey) Subject: Help on SONY 2001 mods wanted Message-ID: <530009@hpdml93.HP.COM> I saw a base note on mods to the SONY 2010.

This is one of the reasons I settled on the 140. Out of all the purchases during that time, the 140 was by far the best. It's really nice when you buy a product and you wind up with more features than you expected. One of the nicest features that I leveraged off of (while getting over "mic-fright") was the 10 memories reserved for "band-spreads". In these memories you program in two frequencies: a low end and a high end. While operating in these tunable memories, if you "roll off" the top end, it loops you back to the low end. As long as you're in this memory, your legal. So far, I haven't found this feature on any other rig (though it is not something I've researched). I work mostly CW and have no problem getting out a good 100 watts. I have worked several other 140 owners and have not heard any bad comments about the rig. In addition to CW, I also have it connected to a PK-232 and do RTTY and PACKET. I'm having a little RF feedback causing me some PACKET problems, but I have to do a lot of work on the wiring and 232 before I can blame the 140. The only changes that would be appreciated would be if the squelch and power controls were reversed (the power is a very sensitive slide switch and would be better as the rotary POT) and if an SWR meter was included. But, in that price range you can't expect everything. Good luck with your decision es 73 Gene Marshall - AA6IY Cupertino, CA (15M CW) ------------------------------ Date: 15 Dec 89 14:30:30 GMT From: victim.dec.com!reisert@decwrl.dec.com (Jim -- LTN1-2/H03 -- DTN 226-6905 15-Dec-1989 0932) Subject: Pacific on 20 Meters Message-ID: <8912151430.AA14796@decwrl.dec.com> Last night I heard ZK1DD on 20 SSB around 0410Z, and worked KN0E/KH3 on 20 CW about 0450Z. There was almost no propagation northeast (into Europe, Asiatic Russia), a little East (ZS1VP, FH8CB and FR5ZD) and south (HC8/HC1LT, CE0OGZ, OH6NTO/CE3 and ZP6XDW). This was all between 0400 and 0500Z. The signals were not great, but perfectly readable nonetheless. jim, AD1C =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= "The opinions expressed here in no way represent the views of Digital Equipment Corporation."
