To: info-hams@ucsd.edu HELP! Industry is invading our 10 Meter band! There are several industrial RF devices, perhaps poorly configured RF thermoplastic sealing machines, which have invaded our 10 Meter amateur band. You may not even be aware of it, but some of the serious noise, swishing, buzzes, squeals and drifting garbage is what we NEED TO LOCATE and have the FCC take action on. I feel that I can provide some general information on the matter, but we need YOUR HELP too. My amateur activity on 10 Meters, and yagi antenna has given me a fairly good feel for which general part of the country that the worst industrial interference is coming from. Before I continue, keep in mind where I receive from, (Massachusetts) and that you may or may not be in the proper skip area. Lets hope that someone may be near enough to hear the offender(s) on GROUNDWAVE! I ONLY hear it when the band is open to the general area described below, AND IT'S STRONG! When the band is open from my area to the South Central part of the continent (perhaps Texas or New Mexico) I hear most of this trash. Specifically, what you will hear are unstable, cyclic and drifting AC modulated signals cross great portions of 28.5 to 29.5 Mhz. Gathering accurate information on the specific problem is a must if we are to keep our bands clean. Although everyone's effort is important, please don't provide the FCC with "wild guesswork". The closer we are able to get to the actual industrial firm or acutal address, the better. I would be very interested in hearing from anyone that has a GOOD IDEA where this junk is coming from. The FCC should be contacted too, of course. Lets get industry off our non-shared band! 73, Roger, W1OJ.

The ferrite usually has much higher mu (higher inductance for a given number of turns), but it also saturates more easily. It is usually used only for applications with essentially no net flux through the core, i.e. transformers (such as baluns). For inductors, where there IS a large flux through the core, you want powdered iron. It has lower mu, but saturates much less easily. If you use the Amidon powdered-iron KW balun core, it should be good for 100 watts as an inductor in a tuner. You really should calculate the core flux density and make sure it doesn't exceed the rating, the the above rule of thumb should work. The inductance value depends on the transmatch design. I would recommend borrowing a commercial transmatch and copying the design. Amidon's data sheet should tell you the microHenries per turns squared value. 73 AL N1AL ------------------------------ Date: 6 Apr 91 07:30:27 GMT From: swrinde!zaphod.mps.ohio-state.edu!unix.cis.pitt.edu!dsinc!netnews.upenn.edu!eniac.seas.upenn.edu!depolo@ucsd.edu Subject: Codeless = worthless?

I seriously hope that your comment was in jest, but seeing no smilies, I'll assume it wasn't. Let's look at your above statement. You don't want to acknowledge Robert (N3IFY)'s achievement in getting his ticket because he didn't know code, or possibly knew the code but didn't bother taking the test, right? Then how do you feel about your own extra class license, knowing full well that you weren't tested on physics of semiconductors, vector algebra for antenna radiation patterns, or digital signal processing, all of which, in some way, have a part in amateur radio? After all, an extra class license is the highest class license - to get it, you should have to know EVERYTHING about amateur radio to pass the test, right? CW is just one MODE, period. It's just like any other mode (ATV, FAX, Phone, SS, etc.). Why should it carry so much emphasis, particularly in the cases where it prevents or impedes would-be amateurs from joining the ranks? The fact of the matter is, it shouldn't. If Robert or any other no-code tech decides he wants to use code, then he or she has to learn the code. Same thing with any other mode - RTTY, ATV, etc. You need to understand it before you can use it. Ramming CW down someone's throat for historical reasons doesn't wash. Neither does the "I had to, so you have to" argument. CW has its merits, just like any other mode. But considering a no-code tech ham to be less of a ham than any other license holder due ONLY to the fact that they didn't pass a code test is disgustingly childish. --- Jeff -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Jeff DePolo N3HBZ/AE Twisted Pair: (215) 386-7199 depolo@eniac.seas.upenn.edu RF: 146.685- 442.70+ 144.455s (Philadelphia) University of Pennsylvania Carrier Pigeon: 420 S. 42nd St. Phila PA 19104 ------------------------------ Date: 6 Apr 91 04:05:12 GMT From: usc!zaphod.mps.ohio-state.edu!unix.cis.pitt.edu!dsinc!wells!k3tx@ucsd.edu Subject: Info-Hams Digest V91 #271 To: info-hams@ucsd.edu Thanks for the nice summary of the old special prefixes 0 0 0 but yes there were some kt prefixes - they were Temporary.
