Section 97.405 Station in Distress (a) No provision in these rules prevents the use by an amateur station in distress of any means at its disposal to attract attention, make known its location and situation, and obtain assistance. (b) No provision of these rules prevents the use by a station, in the exceptional circumstances described in paragraph (a) of this section, of any means of radiocommunications at its disposal to assist a station in distress. ------------------------- Hope this helps everyone. /Matthew (Still waiting for my ticket, 4 weeks and counting) -- Matthew Cravit | All opinions expressed here are Michigan State University | my own.

To: info-hams@ucsd.edu Hello and thanks for reading this. I am a student in Wales (UK) and my dad and I are both licensed radio hams. As there are no packet radio op's around here, we use the Internet gateway N0ARY to communicate. This is an excellent service, however, if such a gateway exists in europe, I would very much like to change on to it, as it would shorten the time for mail to get to dad and would reduce the packet travel time, which is good for packet in general. If such a gateway exists, I would be extremely grateful if you could mail me direct, at the following address :- smd2@aber.ac.uk Many thanks in advance of your replies. 73s de Simon G0HXU. ------------------------------ Date: Fri, 3 Dec 1993 16:41:13 From: news.service.uci.edu!biivax.dp.beckman.com!falstaff.css.beckman.com!capulet.css.beckman.com!srphillips@network.ucsd.edu Subject: Jeep Cherokee '87 Computer Noise! To: info-hams@ucsd.edu My 1987 Jeep Cherokee's Ignition Control Computer under the dash spews the loudest most annoying EMI I have ever heard on 2 meters and 220. Has anyone a cap fix for this? I have all the service manuals to do the repair from scratch but I thought someone on the net may have already done this. The spark noise from the distributor etc. is not nearly as loud as the computer with just the key on and engine off!

One major question I have is: (I mean I agree w/ the acceptable use of emergency comm out of the ham band etc.) back to the question: Isn't it the cellular phone company's responsibility to make sure their customers realize that their conversations are NOT private- and that they CAN AND WILL be listened to? I mean, really folks, congress just passed another law that saved the big and powerful businesses (here the phone guys, other times the coal/oil industries) a lot of money. If this law wasn't passed poor little Mobile Link and Comm1 and all those other fellas would have had to shell out Millions (maybe more) to make their services more secure agains the general public. (Not to mention that all the old cellular phones would be crap, and that the new ones not only would cost more, but would be a bigger). So, here we see congress helping little old us the public by saving all the big phone companies the hastle of having to tell their (not so smart users -not inclusive) that the great new way of communication- cellular phones- is not as secure as you may think. I think that the mobile-phone companies should explicitly say that the phone calls are easily monitored by an FM reciever. I have heard many many things before on cellular freqs. (the on thing that really supports my above sentence is that I onee heard Name, Mastercard Number, and Expiration date all give out on the freq. -come on folks!- how easy can you make it for someone to steal from you?!? (I never stole from them because I just enjoy radio communications as a hobby and not as a way of life -although sometimes it may seem like that ;) (hope we don't feed the flame war too much, but talking about it helps to ease the pain) 73's et TNX, Allen Hall n9rzc@uiuc.edu (I will try to keep up w/ any of the rest of this string, but if anyone wants to post a question directly to me, please

AXD and AXH are really more appropriate than TXD for coping with a repeater. AXD is the keyup delay of the repeater; AXH is the 'hang' (delayed-drop-out) time. The TNC will insert a delay of AXD length at the beginning of a transmission if there has been more than AXH time elapsed since the last transmission or detected carrier. In other words, the TNC takes a good guess at whether the repeater is still keyed (or on a trunked system, if the channel assignment has expired) and doesn't delay if it's not needed. That's better than using TXD, which would delay EVERY transmission, even if not needed. - Brian ------------------------------ Date: Wed, 1 Dec 1993 17:15:26 GMT From: swrinde!cs.utexas.edu!math.ohio-state.edu!darwin.sura.net!fconvx.ncifcrf.gov!fcs260c!mack@network.ucsd.edu Subject: Poor Man's Spectrum Analyzer --- comments?

The guy who made hte kits was quite helpful on the phone. You don't see much below a certain limit (I forget what maybe <10MHz) because of some inbuilt limitation. Also you need to get ground and other loops our of the connection to the CRO, or else your output is noisy. I haven't used mine for about 5 years now. I really never did much with it becasue it never got into a box and at that stage there was no easy way of telling freq (you had to get out your ovoltmeter and do some things). There are improvemtns to the set up - someone has made a better swawtooth generator and I believe there's a freq readout now.

I don't recall if I commented on this before, but the FCC regulations (Part 97) say something to the effect that if there is eminent danger to life or property, an operator is authorized to use _any means at their disposal_ to obtain assistance (emphasis mine).

What I am specifically looking for are a fair to gud Windows Packet pgm and a Windows based Rig keyer pgm. I hv seen a commercial package that is a complete logging, packet, rig control package (Logview, Packview, Rigview), but feel the performance of the Log database is terrible (at least for a 386sx!). If you hv seen anything gud or hv written one urself, plz let me know. Tnks. De KA3PLS, Ken....
