Fine gentlemen of the reflector, As I am becoming once again enamored of the spectre of the hobby, I'm finding pseudo-professional groups (read: DX clubs) interested in engaging my services for custo
This information is furnished under seperate cover AFTER the amp is purchased by the end user. If operation above 15 meters is not possible during type acceptance testing, the amp passes this regula
Technically even that is questionable, although if the manufacturer asks for a copy of a valid license then the FCC considers it OK. The reasoning is it isn't contrary to FCC rules for an amateur to
Hi Charley, No-where is a big place. "Instructions for operation or modification of the amplifier ........in a manner contrary to FCC rules." Of course Part 2 and other areas of the rules clearly sta
And how about "metering" accuracy? Quoting some words by Peter G3RZP a few days ago about accurate knowledge of our rig's output power at legal max.: "Hewlett-Packard rates their generators as +/-1d
I go by what the people in charge of enforcement tell me. They can understand the gibberish in the rules better than I can. What I've learned is doing what they want is easier and cheaper than argui
Why would a CBer buy a 4-5 w radio when 200w ham-type radios are readily available? Trying to limit technical information is an excercise in foolishness. . To: <amps@contesting.com> - Rich..., 805.3
they use those amplifier to "drive" the BIG amps, like Henry 10k or even 1200 watt ham or commercial amp. I believe that the 50 watt drive requirement is a deterrent, but not a inhibiting problem fo
Well said, Tom. There was a wonderful example of this a few years back when a book on monopulse radar was published in the US. According to a guy I know who worked at China Lake at the time, the US N
I guess most authorities will figure that the ham with a Bird thruline or similar is 'good enough'. It's only if they really have reason to nail somebody that they'll get nasty. For instance, I'd sus
Not so easy, unfortunately. An European directive is not yet a law and that directive is a sort of headline, incomplete with specific electrical parameters (numbers). Until single governaments will n
Actually, Maurie, amateur radio manufacturers in Europe can self certify transmitters under the EMC Directive, Article 10. They are the only group who can self certify transmitters, and it is basical
The EMC(LWD included) are tests for CE marking of electrical devices. Then, it has to be made a clear point if an object requires or not the omologation to be operated. If the omologation is required
FCC 97.315 clearly states that an amplifier may be modified by an amateur radio operator (1 per year). FCC 97.317 stated the requirements for type certification. Any input attenuating device which wi
Hello Tom: I stated "no where in FCC Part 97 10 meters in 1500 PEP output except for the portions of the band which are accessible to the Novice & Technician Plus licence holders. If FCC 97.315 allow
In the 50's and 60's versions of the FCC Rules and probably earlier than that there were references to having measuring devices" to measure the DC input to the power amplifier final stage. This was c
