And "first choice" and "second choice" don't mean one is more correct than the other. Either is correct. Webster's Ninth Collegiate says: pl _baud_ also _bauds_. And, on page 11 of the dictionary, it says: When another spelling is joined to the main entry by the word *also*, the spelling after *also* is a secondary variant and occurs less frequently than the first... Secondary variants belong to standard usage and may be used according to personal inclination.

To: info-hams@ucsd.edu Somewhat along the same lines. . . I purchase two Panasonic LCR12V2.2P lead-acid batteries for use with the HTX-202. These are fairly nice 2.2 amp/hour batteries that are about the same size as my HTX-202. I've used these batteries for hours on end without having to recharge them -- much better than the stock NiCds. The only "problem" I've run into so far is charging them. I have a small lead-acid charger of the type you can get in the Automotive departments at Wal-Mart, K-Mart, Target, etc. that is settable between 2A/6A charging rates. So far this charger seems to be working well but it's a manual type and I'm not sure how long I should charge the batteries. What I've been doing is letting the battery drop to about 10 to 10.5 volts then throwing it on the charger and checking it every 30 minutes to an hour with a DMM. When the battery voltage increases to about 12 volts, I remove them from the charger and put them back in the carrying case. One thing is absolutely accurate: I could use some tips on charging lead-acid batteries. The particular ones I have are stamped "Constant Voltage Charge" with the ratings "cycle use: 14.6-15.0V and standby use: 13.6-13.8V." Inital charge current is rated at 0.88A. -- Greg KE4DPX ------------------------------ Date: 8 Nov 93 22:50:42 GMT From: ogicse!emory!kd4nc!ke4zv!gary@network.ucsd.edu Subject: characteristic impedance To: info-hams@ucsd.edu In article <9311081152.AA32868@swmis> P.Lucas@mail.nerc-swindon.ac.UK writes: > >No-one has yet pointed out that you can 'measure' it directly!

That formula will work for *air dielectric* lines, but isn't correct for the more common cables with solid dielectrics of various values. There's no easy way to determine the dielectric constant of a cable by simple inspection. You can attempt to measure the inductance and capacitance per unit length and apply the formula Zo=sqrt(L/C) Gary -- Gary Coffman KE4ZV |"If 10% is good enough | gatech!wa4mei!ke4zv!gary Destructive Testing Systems | for Jesus, it's good | uunet!rsiatl!ke4zv!gary 534 Shannon Way | enough for Uncle Sam."| emory!kd4nc!ke4zv!gary Lawrenceville, GA 30244 | -Ray Stevens | ------------------------------ Date: 9 Nov 93 04:05:15 GMT From: news-mail-gateway@ucsd.edu Subject: Daily Solar Geophysical Data Broadcast for 08 November To: info-hams@ucsd.edu !!BEGIN!!

One can tune the band and find no, or very few, signals. Even when the band is obviously open, one may find very few signals. As an example, I worked two different stations on Pitcairn this last weekend and the weekend before. During the CQ contest, lots of activity on 10M. This weekend, not many signals, even when the band was open. Of course, I usually listen up and down the band for signals, rarely calling CQ. I think many folks do the same. If you think 10M is dead, try CQ a few times. You might be surprised. > >On numerous occasions I've gone up to 15 meters when it seems >absolutely dead, tuned around looking for anything interesting and >finally called CQ just before giving up, only to have several booming >signals answering my call.

There are penty of new hams in DX locationsthat are in the same boat as new hams here struggling with operating procedures and code speed. The point is you can't expect to work a Bouvet or Peter 1 dxpedition until you have developed the skills required to do it. There will be plenty of operators with excellent skill that miss out on a dxpedition like that. Run with the little dogs for awhile and develop the correct techniques, before you know it you'll be elbowing it out with the wolf pack in the pileups. The Novice license used to be kind of like a bunny slope at a ski hill. It gave you a chance to operate with others at your skill level so that you would be ready for what goes on in the other parts of the band. It is too bad that so many hams are skipping over this and missing out on a valuable part of their training.

I passed my Novice in November 1984. I didn't have a radio, and no means to get on the air. My first QSO was in June 1986. I had FORGOTTEN most of the letters! The novice bands were a fun, controlled environment where a 45-minute QSO, in which all you got to exchange were name, QTH, RST, and some basic info (yup, it was slow), was absolutely great. Chase DX on 15 and 10 meters, and during the winter, go down on 40 and 80 to chase the WAS. If I could have done the no-code, I don't know that I would have developed such a keen interest in the HF stuff, because 2 meter FM is SO much easier to do - kind of an instant gratification thing. Gee, I couldn't even get on 10 meter phone then! I SO anticipated getting my 13 wpm so I could plug in the microphone. Guess what... My 100 watt rig with a dipole just couldn't fish through the big pileups. It was OK for basic ragchewing, but if somebody came in 1 kHz away, the contact was over. I found myself getting <> frustrated with SSB. Every time I flip on the radio, and go down to the phone band, and realize how susceptible it is to interference, even with filters, I go back to CW. It requires skill, on BOTH ends of the contact. It uses very little band- width and can be filtered like mad. Last Field Day I was running QRP with a dipole. On phone, I made 0 (ZERO) contacts in 2 hours of trying. On CW, I made about 140 in 12 hours of operating. Rarely had to call more than three times to get through. Simply put, say what you will about it, for most of us CW is a much more reliable mode than phone when working on HF, VHF, UHF, or really anywhere else. SSB spreads that power out over a few kHz. CW has a punch. The Novice license got me hooked - it was the only way in. I LIKE the no-code license. My fiancee is a no-code. I'm just afraid, like many others who are religious CW ops, that people who could really enjoy CW are simply not learning it because there's DEFINITELY no instant gratifi- cation. None. CW is a BITCH to learn and get good at. I'm still not all that good, even though I can zip along at 25 wpm. I still make a LOT of mistakes, especially when using the keyer, and I certainly don't copy every single character that goes into my ears. But I get enough to fill in the blanks. After 6 years of CW operating, I FINALLY started to copy words instead of characters. SIX YEARS of operating!
