Often, two hams will spend more time trying to convince each other how sorry they are to have to end the QSO, then they do in actual conversation. The following recreation is typical: KG7OS: CQ, CQ, CQ, this is KG7OS calling CQ and listening... KB7LVU: KG7OS KG7OS this is KB7LVU KB7LVU over KG7OS: KB7LVU, you are 59 in Vancouver, Washington. How copy? KB7LVU: KG70S, you are also 59 in Seattle. KG7OS: Roger, LVU. Sorry, old man, but I have to QRT now. The wife asked me to put the cat out, and if I don't, she'll throw *me* out. KB7LVU: Yeah, I know what you mean. I have to go, too. My daughter asked me to do a few things for her today. KG7OS: I'd love to hear about it, but the cat's really starting to smolder now. I really should throw some water on him or something.. KB7LVU: Uh-oh! They just started the wedding march. If I don't get downstairs before she starts walking down the aisle, I'll never hear the end of it! 73 from KB7LVU! KG7OS: Oops! That stupid cat's got the draperies burning now, too! 73! KG7OS Clear! Of course, six seconds later, KG7OS was calling CQ down 5, and KB7LVU switched bands and did the same. While Miss Manners would no doubt approve of each ham's efforts to spare the feelings of the other, as do I, such herculean efforts are a needless waste of bandwidth. On the other extreme, one ham would go suffer from selective deafness on hearing the other's call, and the conversation would not take place at all. Slightly less extreme would be brutal honesty: . . . KG7OS: Roger, LVU. Look, you sound like a real jerk, so why don't you go away, and give someone with half a brain a chance at answering my call? KB7LVU: Sure thing, OS. I've got better things to do than talk to an old geezer like you. Why don't you go downt to the hypochondriac net on 160, and tell them all about your prostate surgery? KG7OS: Why you whippersnapper, I oughta... ...and so on. You get the idea: though more honest, the direct approach still wastes bandwidth. I propose we replace "73" (and its illegimate and much disdained sibling, "73s"), with the following: 129: No offense, Methusela, but I'd rather chat with someone born in this century. So long, and don't overdose on your Geritol! 3: No offense, sonny-boy, but I'd rather talk to a grown-up. Can you give mommy or daddy the microphone? 35: Sorry, but if my wife caught me talking to a YL she'd take a sledgehammer to my rig, and then go after me. (on a repeater, this can be followed with an invitation to meet somewhere for an "eyeball" (or is it "eyefull"?)). 6: California is NOT "DX". I said "CQ DX", not "CQ IDIOTS" 7.5: You're a bit dim. Turn off your radio, and let me talk to a person with a brain. 40: Huh? Are you still yakking away? Get lost before you put me to sleep. This only covers a few of the many possibilities, but you can easily see how much more efficient this would be: ... KG7OS: 7.5! KB7LVU: 129! I'm sure the ARRL is already collecting suggestions, and will shortly submit a list to the FCC for approval.

Your assertion is false. A repeater may operate under automatic control, 97.205(d). A control operator need not be present when a station is operated under automatic control, 97.109(d). A station licensee operating a station under automatic control is only obligated to cease automatic operations if notified by the Engineer In Charge of his district of harmful interference, 97.109(d). The FCC has consistently ruled that it is the originating station who is responsible for improper content of automatically repeated transmissions. Only in the case of third party traffic is a repeater licensee responsible for content, 97.109(e). No phone patch, no problems. Don't be misled by recent FCC statements regarding digital messaging systems (IE they mean BBSs). In that case, all retransmissions involve third party traffic.

That's what you're doing when you restrict access to only those who pay to use your system. Get a commercial license if you want to operate a radio business.

I assume you want to use the car antenna on other than the broadcast bands. I use my car antenna ('87 Accura Legend) on 144, 220 and 440 MHz with a homebrew band-switched tuner. The actual antenna impedance is not of much interest, since the impedance at the other end of the coax will be completely different. It will depend on the antenna length, coax length, and coax impedance. (And to a lesser extent on the antenna placement and shape of the car body.) I suggest doing what I did -- Just hook up a good VHF SWR meter and fiddle with the matching network until you get a 1:1 SWR.

Many years ago I worked briefly (a few weeks) at a stereo/TV repair shop. The owner was, IMO, a crook, if not legally then at least morally. Prices were based more on what he thought the customer was willing to pay than on what it actually cost to fix the set. If the customer asked how long the repair would take, I was supposed to say "a week." But I knew that there were shelves full of sets waiting to be worked on in the back room. If an irate customer came in weeks later wanting to know where his equipment was, I was supposed to say "on the bench waiting for parts." (That way, the customer couldn't yank his equipment and go somewhere else.) The owner got all his business by going through the paperwork to qualify as an authorized warrantee repair center for just about every consumer electronics vendor known to man. You see, that way he don't have to depend on repeat customers to stay in business. The whole experience accounts for much of my lost naievte as a young man. :=) AL N1AL ------------------------------ Date: Mon, 06 Jun 1994 14:54:36 GMT From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!howland.reston.ans.net!spool.mu.edu!cass.ma02.bull.com!claude!zds-oem!news@network.ucsd.edu (Reid Simmons - r.simmons@zds.com) Subject: TEN-TEC transverter To: info-hams@ucsd.edu In article <1994Jun1.104107.1@leif> jcraig@kean.ucs.mun.ca writes: >In article <2shqit$bi0@usenet.INS.CWRU.Edu>, co128@cleveland.Freenet.Edu (James J Martin) writes: >> >> Ten Tec 6 meter transverter kit (1208) for up to 5 Watts in on >> 20 meters will give you 8 Watts out on 6. >^^^^^^^^^^^^ >> >> kit $95.00 >> assembled $159.00 >> >> There has been a delay in shipping. >> -- >> JIM MARTIN W8AC >> co128@cleveland.freenet.edu > > >Does the xvtr really use the 20m IF?

I'm impressed with the circuit (16 transistor design). The SSB/AM/CW activity on 6 is at the extreme low end of the band (<50.5 MHz), above that is mostly Radio Control (for model airplanes, and FM repeaters). I plan on using mine with my TEN-TEC OMNI VI which tunes up to 14.530 on the 20 meter band - plenty of frequency coverage for serious 6 meter work.

It would have created a nightmare situation because of the impossibility of tracing who was newly licensed and who was bootlegging. The League has been pushing the FCC to implement Electronic Filing of applications, whereby the FCC would NOT have to waste time keying the data. The ARRL VEC has been online to do this for some time, and the bottlenecks on this have been at the FCC end (getting the new computers online, etc.). Please keep in mind that the ARRL has been working on SENSIBLE solutions to the licensing delay issue when you go and vote. -- --------------------------------------------------------------- Daniel Senie Internet: dts@world.std.com Daniel Senie Consulting n1jeb@world.std.com 508-779-0439 Compuserve: 74176,1347 ------------------------------ End of Info-Hams Digest V94 #637 ******************************
