SO WHAT, now you have EXTREAME QRO amp, they hear you: 200 dB over S-9
BUT you have NO antenna to HEAR them! I'd rather hear them, then talk to them with my 100W mobile with a Hi- Q-HF antenna. Charlie, VA7HIQ/W6 Charlie, you make a wrong turn on the 405? Where's your amplifier? Dreams, Fantasy's and Desires? It's just not acceptable to say I've done it all until they flip the lid shut for the last time. I've got 30+ years mobile. You aren't really making RF until your AM radio's front end has blown out, you've made the electronic fuel control on your diesel pickup "Shut OFF" or backfire while towing on the freeway, and your trailer brake controller needs RFI protection to keep from locking up the brakes every time you talk on the radio. The rig has dual batteries but have also added an extra alternator just incase to keep things up to snuff. You pull up to a toll booth on the Jersey Turnpike and smack all the light fixtures with your antenna bent over about 5 feet... The toll booth lady looks you in the eye and says, THAT'S NOT A LEGAL HEIGHT ON THE TURNPIKE and you answer, OH that's for measuring bridge heights, I'm a contractor working for the state do you want to see my authorization? Turning and mumbling its right here somewhere... Hey, It's totally adjustable, see look watch it go up and down, whirrrrrrrr.... Pull out of the booth, yeah standby I have to retune... You wouldn't believe what I had to do this time guys... Any mobile less than 1KW output and shorter than a 14 foot tall antenna is just more QRM on the band. Yeah you can hear them all right but you are the same guy they say... WHO'S the MOBILE IN THERE? Try again.. I'd rather have them say... "YOU'RE MOBILE?" WOW... My mobile has always been louder than most 100 watt home stations. To do mobile right, you take an acceptable vehicle platform, install 200 amp wiring, the optimum antenna, the best rig and the biggest amplifier. You then work all the bugs out of the vehicle until it tolerates what you need to do for radio. You can never run ENOUGH power mobile and that takes an amplifier. That's REAL RADIO.

You could probably get away with putting a penny in the fuse holder and just look out the window at your pole pig and “tune for the most steam” coming out its vent. ? Hal ? [snip] [snippety-snip]

Does that Combat Zone nonsense still occur** The Combat Zone was a one-time eruption that began c. 1975 and started to fade after about a decade. The dénouement was when we started discussing a subject that made a whole lot of the denizens nervous. After those discussions began, c. 75% ran -- some even dropping out of Ham radio altogether. Many of the regulars who didn't flee are now silent keys - or microphones. The remaining old- timers moved to 7255 because 7258 was taken over by drug and/or ethanol-dependent stations. Occasionally I hear a familiar voice and say hello. or did Riley drive all the jammers under ground?** No. Jammers are pretty much like death and taxes. In rare cases however, a jammer will have second thoughts and he will give it up. Example: Fresno, California. There was a virulent jammer whose location was discovered. He was contacted and advised to stop jamming but he kept on. One night in the wee hours someone drove by and discharged a number of warning rounds from a .308 caliber semi- auto rifle through his residence in such a way that no one would be likely to be struck. According to reports, the bullets went completely through one side of the residence, through interior walls, and out the other, and into a cotton field -- so he undoubtedly got the message. No one was injured. The jamming stopped. ** never ran into him. As I see it, jammers are often little boys who did not get the right kind of attention from their fathers prior to the age of 12 - 13. One of the most persistent 80m jammers in Southern California turned out to be from a entertainment-business family that apparently had a number of male members who had a carnal interest in little boys. cheers, Greg ...R.

You did not mention the saved monies otherwise

Actually it should be obligatory for any ham to own

Subject: [ham_amplifiers] Re: God Complex Extremely high power makes for an interesting experiment thats all. I have not used my big box on real antennas for many many years. However i still fire it up into a dummy load, and i still try and improve its circuits. Does that make sense probably not Anything above 1 kilowatt is very hard to justify on the needs of a communications circuit. I would argue that its only the lower bands where it may be of some help. Even then its hardly needed and is only helpful in the case of jammers etc. Its shame having a high electricity bill because someone else has a poor receiving location! Very few stations these days have the ability to radiate the power at the low incoming angles where it can do some good. With our greater understanding of NVIS propagation, a good NVIS antenna like a vertical yagi firing straight up in the air can just about compete with a 20db amplifier if its a short range circuit What gets most people unstuck running high power is either the ego or using one of the modern ham radio exciters as a driver. Its very hard to find a radio thats clean enough without generating snide remarks about signal quality. Lets face it just about every radio transceiver reviewed by the ARRL is as bad as the last bad lemon in this regard. Now this is a problem even for those running legal power. Most of us can build these amplifiers but few are willing to build an exciter thats clean enough to match the excellent signal purity of big amps. Maybe if the FCC changed its rules and allowed amplifiers that can be driven with 100 milliwats like every military amplifier this terrible situation might change. When i get stations telling me in a sincere manner that a crapped out old L4B makes 20 db of difference, imagine what can be expected if you asked for a signal report on the difference that a 20 db amplifier gives! If most stations used true calibrated S meter's they would not be rushing out to build or buy a high power amplifier considering the expense. A case in point is the high power fax station somewhere in Germany, listen sometime, Its on 13.381 or 382 DDK or DDH. It runs 20kw into a vertical for weather fax. I can hear most hams better who are using a low tribander than this station. This station is in an impressive location and it uses a optimised antenna. Its a good propagation beacon. This station essentially illustrates the futility of running high power. When the band is open the signal is impressive, when the band is marginal any ham with a decent antenna is heard with a better signal strength. I would say most hams play it legal simply because running high power in the places where most of us live is out of the question. Hams i think have extracted the maximum performance one can expect out of antennas and propagation, there is hardly anything to prove. In commercial shortwave link circuits this very same thing has occured with shortwave planners, the shift in power is downwards not upwards because even the military has too consider the economics of high power. The power level is dropping steadily, when once it was the norm for a military link station to run 40 kilowatts, 1 kilowatt with good antennas is the norm now. Most tactical planning for long distance links have a target power range of .400 too 1 kilowatts of power.On SSB 4 kilowatts is about the maximum power used. The Rockwell Scope HF system is an example. Just my take, as others can justify the need for gas guzzlers so too i am sure someone else can justify the argument for running high power and think it makes sense. Now if the electricity was free and i had a modern DSP transceiver that cancelled out the distortion and IMD as i spoke i might change my view. If i had the choice between high power and a hilltop location with sloping terrain in all directions i would take the hilltop location over the 20db amplifier any day. Better still is a saltwater island with verticals, i then could run these stations on solar power and achieve the same thing without contributing to global warming!
