I asked to speak to her supervisor and asked him when did the state of Arizona reclassify amateur radio plates as vanity plates since amateur radio plates had been around long before vanity plates? He looked it up and found that amateur radio plates are not vanity plates and are a lot less expensive than vanity plates. Knowing ADOT, it wouldn't surprise me if they had instructions to collect vanity fees for amateur radio plates if the amateur doesn't object. 73, Cecil, kg7bk@indirect.com ------------------------------ Date: Mon, 1 Nov 1993 18:24:22 GMT From: pa.dec.com!nntpd.lkg.dec.com!peavax.mlo.dec.com!usenet@decwrl.dec.com Subject: CQWW checklog To: info-hams@ucsd.edu In article <9311010830.AA27984@ganges.beeldanalyse>, G.POLDER@CPRO.AGRO.NL writes: > can I send my CQWW checklog in by e-mail ???

Among the bargains I found at the Hamfest this weekend in St. Paul MN, was the following Oscilloscope for which I now need manuals etc: 140A Oscilloscope Hewlett Packard I don't know the age of this beast. It is quite heavy. It has the following modules: 1423A Time Base Hewlett Packard 1402A DC 20MCI6CMI Dual Trace Amplifier Hewlett Packard. I don't know if it works at the moment. I still have no power chord or test probes. Then I paid a total of $17.50, so if it never works it wasn't too much of a loss, and if it does work I really have a nice find. Can anyone tell me anything more about this unit? How old would it be? How can I tell what the maximum frequency it can handle is? Am I resigned to paying several times the price of the scope for the test probes? (I need 2 of them.) Does anyone know how I can find a service manual? Other manuals? Help! ________________hamfest observations_______________________________________ In general I felt that there was not much radio equipment and lots of computer equipment at this hamfest. There were quite a few oscilloscopes there, so bargains were to be had. This pleased me since this was on my shopping list. I got a nice temperature controled soldering iron. (Hexacon Therm-o-trac $20) I didn't see a single straight key. I saw many glow in the dark boat anchors going for many hundreds of dollars. (Ok, I didn't see them go, but that was what was being asked. Sombody had a couple of nice anchors from "Collins". One for $300, and one for $200. Another person had a "Schwan" was it? 100 watts on 10 and 11 meters. Glow in the dark rig. He wanted $200, and then "$175, but that is my best offer." I saw a HW 101 going for $100. I probably should have taken that one. Someone else did after I passed it up. I saw those others all there at closing time though.) --- ______ Sourdough and Ham KG0IO/AE | | | | | | obten comida, --David C. Adams dadams@cray.com | | | y sal de aqui!

NODXA member Walid, OD5ZZ, informed OPDX that this award will be issued by the "President Karami Radio Society" (PKRS) for any amateur station who has worked 10 different PKRS members on two different bands between the period of November 15th and December 15th (1993). The same station can be worked on more than one band and one of the contacts must be with OD50RAK. The station OD50RAK will be active daily on 14308 kHz (time was not given). The GCR rules will apply for all stations. A special plaque will be available to any station that meets the above requirements but on five different bands on any mode. The fee for the basic award is 5 USD and fee for the plaque is 25 USD. Requests for the award can be sent to: OD5ZB, Bassem Sibai, P.O. Box 782, Tripoli, Lebanon, Asia. PKRS stations are: OD50RAK, OD5JY, OD5KM, OD5LT, OD5PL, OD5RF, OD5SA, OD5SB, OD5SC, OD5SF, OD5SH, OD5SK, OD5QH, OD5QS, OD5WD, OD5XY, OD5YL, OD5YT, OD5YU OD5ZB, OD5ZN, OD5ZM, OD5ZZ and AA3EI. 8Q7, MALDIVES.

I believe that it has to do with one of the lvels in the radio. I don't want to mess with my 850 so I just put a toggle swithc in line and cut out the one wire that was causing the problem. I think if you unplug your mike it should do the same thing. When I switch form Digital to SSB, I thorugh one switch. I think a better solution is to use the FSK instead of the AFSK/. this way you can use a CW filter in line. I am going to switch my cabling when I get a chance.

To: info-hams@ucsd.edu There's currently a discussion about workbenches for *woodworking* in rec.woodworking, but I assume you want one for electronics. For over 15 years I have used the following scheme for electronics workbenches with success. I employ two 2-drawer file cabinets to support a top, which is actually a solid core wooden door, obtained as a reject from a lumber store. On top of that, I placed steel shelves to hold a scope, lot of meters, sig jennies, etc. Instead of building a 6 foot tall set of shelves, I built two sets of 3 foot tall shelves and sat them on top of my workbench side by side. I used industrial steel shelving, but you could the cheaper Hirsch "Erector Set-type" steel shelving available at most home center stores. Lots of test equipment sit on the shelves, plugged into a 6' long AC outlet strip which rests at the rear of one of the shelves. I store equipment repair and user manuals in the file cabinets. PS - Scott Landis' "The Workbench Book" is a good book if you are considering a woodworking bench. It's published by Taunton Press. -- ============================================================================== Copyright 1993, Bob Parnass, AJ9S AT&T Bell Laboratories - parnass@ih4gp.att.com - (708)979-5414 ------------------------------ Date: 2 Nov 93 03:25:07 GMT From: ogicse!uwm.edu!news.moneng.mei.com!howland.reston.ans.net!noc.near.net!news.delphi.com!usenet@network.ucsd.edu Subject: Yaesu FT-890 TX Mod Information To: info-hams@ucsd.edu If anyone is interested, following below is the TX mod for the new Yaesu FT-890 HF rig.

Remove the two side-mounted screws that will allow the front panel to hinge forward. 3. Look for jumper spot JM3001 on the display unit. It is located behind the front panel, near the top edge of the board. It is very small and has a circle around it. Make a solder bridge across JM3001 with a fine-tipped iron. 4. Turn power on and off. 5. With power off, press and hold PROC, AGC-F, IPO, and ATT buttons simultaneously (you may need an extra hand! :). 6. While pressing these buttons, turn the power back on. 7. The display will show two digits and "on" or "off". Rotate the main dial to make it display "02-on". 8. Press PROC button to write the data to memory. 9. Turn the power off and remove the solder bridge from JM3001. 10. Reassemble the radio. The modification is complete.

There are other references kicking around, and for a completely up-to-date one, see if you can track down the September and October 1993 issues of _Electronics & Wireless World_. The September issue has a very good overview of spread spectrum (concentrating on direct sequence), and the October issue has construction information on a 435 MHz direct sequence spread spectrum system. The articles were written by James Vincent, G1PVZ. In typical spread spectrum fashion the transmitter is (relatively) simple, while the receiver is quite complicated. It uses some very interesting techniques for acquiring and keeping correlation, and does not need an external reference like some of the stuff in the ARRL spread spectrum book... Just in case, no, I have no connection with E&WW, or with Reed Business Publishing. I have no idea who Mr. Vincent is, though I do like his style. 73 from Burnaby laura VE7LDH ------------------------------ End of Info-Hams Digest V93 #1301 ****************************** ******************************
