That's because you didn't tune *high* enough Cecil. :-) The amateur satellites are extremely predictable, can offer near global communications, don't require maximum legal power, and aren't as much at the whim of the solar cycle. The phone companies quit using high power HF SSB for international circuits years ago. It's time more amateurs learned they don't need that sort of setup either to work stations in other countries.

In California this involves mutual aid whereby local authorities turn to an "outside resource" (outside of their jurisdiction) to augment their own forces (or where none exists) to accomplish their mission. Either way (i.e., augment or provide) the so-called "outside" mutual aid people are ALWAYS under control of the REQUESTING government. The structure by which that functions is part of the Incident Command System. In communications involving responding FCC Amateur licensees this aspect has at times been misunderstood by those not familiar with how mutual aid works in fire and law. Those "outside" resources NEVER come in to "take over". Mutual aid does NOT belittle the locals, but augments them with professionals trained in mutual aid response from other jurisdictions. It is inconceivable that any jurisdiction would ever call in distant professionals to spite the locals, as we once heard it expressed by an exasperated amateur. It just ISN'T done for a number of very good reasons. Just because there are local FCC licensed Amateurs doesn't necessarily mean a government will call upon them in an emergency if they haven't been active, trained in and familiar with a RACES or similar communications reserve program. It is professionalism, whether paid or unpaid. No professional ever responds in mutual aid to do anything other than to support the local needs. That is the true mark of a professional (paid or unpaid), whether law, fire or communications. Any communications responder who is such an amateur that he/she can't discern the difference between amateurish activity and professional activity shouldn't be responding no matter how well intended. Instead, that person needs to take training and familiarization programs to help understand the mutual aid process. An ACS/RACES response from a city, county, or State OES in support of another government is due to a request from that government. To respond without a verified official request is the height of amateurish activity, and can have severe consequencies except in the most unusual of instances.

There will be a youth net at the Dayton Hamvention on the first Friday night (April 29, 1994) of the event at 8:00 p.m. (Dayton time) of the Hamvention, this net will be held for approximately for an hour. The youth net will be held on the Miami Valley FM Association N8ACV repeater on 146.64 Mhz (negative 600 input). This is the first time a youth net will be held on a local Dayton repeater during the Hamvention, so I hope to hear you on the air. If you have any question, please send me a message to my packet address or to my e-mail address.

The left one sets the menu item, the right one selects the choice. A "save" button saves the setting as the default. Most of the newer and smaller radios are going to something like this.

What it does is prevent a weak or varying signal from sounding like a machine gun. I've designed several radios that required quite a bit of human factors research in squelch action. The Motorola Micor has a very unique adjustable release time squelch circuit. Kenwood decided that it's more important to have a smooth squelch adjustment than a usable signal and threw hysteresis out the window. Obviously, I don't agree with this. Incidentally, I don't listen to moonbounce while driving. However, I live in a mountainous area and signals tend to be weak, choppy, or suffering from multipath. >My settings were fine. Never had any complaints about the mic gain. Did you MEASURE them? I did. >Sure the radio isn't perfect, but as you said, they all seem to have their >problems. If you want Motorola, you have to PAY for Motorola. I see. If I want quality, I should buy Motorola. However, because I'm a ham on a limited budget, I should tolerate design flaws, mechanical abomonations, human factors atroscities, and durability problems. It's funny, but when designing commercial radios, I had the same dumb line thrown at me by the military-aerospace crowd. I guess hams are suppose to take any and all abuse because we're so tolerant. A major stupidity is how the TM732A handles the cross band repeat and remote control. In cross band, if the transmitter is on the air, you can't control the radio. Make the mistake of setting the frequencies backwards on a busy channel, the only way to disarm the monster is to unplug the antenna and punch the magic buttons. Same with remote control, but worse. You can ONLY get out of remote control with another radio using touch-tones. The only thing you can do at the radio is a total reset. I'm sure there's a rational reason why one must effectively lose control of the radio to use these modes. One nice feature about the radio I forgot to mention. On the air cloning. Push the magic buttons and the radio disgourges it's memories and configuration in the form of touch tones on the air. I make a tape recording of the tones. To reload the radio, I push the buttons and play back the tape over another transmitter to the TM732A. I travel a bit and have a seperate tape for each major city I visit. Not documented anywhere. It's interesting that Kenwood would not even mention what I consider a major feature and convenience in the TM732A and TH78A. Inspite of all these criticisms, I still like Kenwood. My experiences with other brands are far worse. I own a variety of other Kenwood radio products and have never had a catastrophic failure or major problem that I couldn't easily fix. -- # Jeff Liebermann Box 272 1540 Jackson Ave Ben Lomond CA 95005 # 408.336.2558 voice wb6ssy@ki6eh.#nocal.ca.usa wb6ssy.ampr.org [44.4.18.10] # 408.699.0483 digital_pager 73557,2074 cis [don't] # jeffl@comix.santa-cruz.ca.us scruz.ucsc.edu!comix!jeffl ------------------------------ Date: Wed, 30 Mar 1994 09:00:54 GMT From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!howland.reston.ans.net!europa.eng.gtefsd.com!emory!wa4mei!ke4zv!gary@network.ucsd.edu To: info-hams@ucsd.edu References <Cn8ttu.AHI@news.Hawaii.Edu>, <1994Mar26.180734.6273@ke4zv.atl.ga.us>, <bote.764956814@access1> Reply-To : gary@ke4zv.UUCP (Gary Coffman) Subject : Re: Plain old repeaters In article <bote.764956814@access1> bote@access1.digex.net (John Boteler) writes: >gary@ke4zv.atl.ga.us (Gary Coffman) writes: >>Mr. Herman wrote: >>>Gary: I'll be disappointed if your repeater beeps. > >>Sorry, you're disappointed.

Sadly, reality raises it's ugly head. Without the beep, people were jumping in when an operator merely drew a breath. If the beep didn't genuinely serve to smooth the flow of conversation, I wouldn't have it on there.
