Total posts : 45366First, the Rangemaster does not have on board processing. The Procaster does however. Also watts is not always watts. The efficiency of the RF output section must be factored in. The Rangemaster operates Class D with an efficiency that approaches 90%. Correct me Neil if I’m off on that. Both the Procaster and the Rangemaster are in a class of their own. Kit-wise the Sstran 5000 with a Class E output is also in its own class. You pay for what you get as they say. There is no comparison between a Rangemaster/Procaster when it comes to the quality of the circuit board construction. Also if you like a transmitter that has FM artifacts the Talking House is right up your ally LOL!

Total posts : 45366The TH is a novelty. I’m not saying a TH is the cat’s meow. I am saying I can achieve similar range results with any of the transmitters if similarly installed. Process your audio and you’re getting the best bang for your buck.
Transmitter efficiency is important but doesn’t it take a doubling of power to gain 3db? All of these boxes have been metered before and aren’t they all in the 80-100mw output range? What’s the argument?

im not a librarian so if you wish to argue my points then feel free to look for citations to invalidate my reasoning.
—————————————————————————
the FCC does not require the AM hobbyist to have a type accepted part 15 transmitter. the FCC requires anyone manufacturing transmitters for sale in the USA to get type accepted or verified but that burden is on the equipment maker. unlike licensed broadcasters, we are not required to have type accepted equipment. we are bound by the rules though that our gear doesnt go outside FCC limits, homebrewed or store bought.
the spitfire is indeed circumventing rules but the way things are written, we’re imuune unless your gear goes awry and you’d be in trouble regardless of what you owned if all of a sudden you started spewing interference.
a hamilton is a transmitter in a box. saying that only the hamilton gets to have proper lightning protection when mounted on an elevated surface is ridiculous. all antenna mounting structures are supposed to have proper lighting protection, that’s proper engineering practice.
the hamilton product may employ a very efficient transmitter but the competitors would have to be 50% efficient to produce a signal 3db down all other things being equal.
lets be clear that i’m not saying the hamilton product is junk. its very well made and an excellent solution for the guy that wants a BAM signal right now. what i am saying is that with some elbow grease you can save yourself $500-600 and achieve a similar signal with a spitfire or similar transmitter.

You wrote “radio8z,

My comments were directed to the claims of “legal” grounding made in post #104, not to what you posted, hence the phrase “previous post”..
My request for documentation was with regard to the claim that the FCC was there during some installs and were OK with this. Basically, how does the poster know this? Personal observation perhaps, or hearsay? It may well be accurate and true but I seek some assurance of this.

Total posts : 45366Okay let me try in shed some light on the subject. A very active member in the New Radio Revolution has given me this information quite some time ago. Unfortunately his computer went to hack and a lot of this was lost but I do trust his information as he’s always given me a and the ALPB valid and useful information.
From what I understand he got this information from an engineer who is been active in making sure that part 15 installations are 100% legal. Somehow Infformation Systems was mentioned as one of the companies that has used this trick and never had an issue with the FCC on any of their installs.
It is interesting to note that this happened after the fiasco of the long ground busting that happened to Ken Cartwright. Anyways the story goes on as the engineer has been using this trick because of the fact that electrical code does trump the FCC’s 3 meter ground rule.
The FCC has been present during those installs from what I understand is from information systems. So with that in mind if they’re able to do this in front of an FCC agent or agents so too can you. And it makes good sense because it’s the same darn thing is if you Were to install a talking house transmitter on the 100th floor of a building because the talking House uses the third prong as a ground. That ground does radiate contrary to what some may believe.
So that in itself makes you legal although it may not look like it but For now electrical safety codes do trump pretty much anything else. Plus did you know that if you have a system that is improperly grounded it could void your home owners insurance? This too is something else that I have found out so all of this makes good sense and the FCC knowing this so far (knock on wood) has not given anyone any hassle for that type of install. If you can point to a link with the FCC has asked someone to cut the third prong off of their power supply of a talking house or I a.m. transmitter because they live on a high-rise or an apartment that is way up in the air please post it because it’s the same thing in essence. So common sense should tell you that this information that I got is valid.
Honestly the only reason I gave this information to nonmembers of the New Radio Revolution was because I was being balked at too many times and wanted to show that the New Radio Revolution is not a bunch of young punks who know nothing about Radio. It does show that we have actually done some of the research ourselves. That in turn we given it to you But in retaliation for being made fun of. Count this one as a freebie from us. Maybe it will help you guys so that you don’t have to continue arguing about such nonsensical things like a ground lead. Now you know how to make your station legal and actually get out somewhere. Welcome to the real world of broadcasting brought to you from the Soldiers Of Chage…The New Radio Revolution.

Total posts : 45366I’ll have to see if I can find anything on it. However like I said life is not always documented as part of a website or link. If I knew the entineer myself and he was actually willing to reveal that information I could show it.
If it were me I’d do it but I don’t have the land to prove it could be done. I’d have a licensed electrician install a socket on top of a 500 Ft structure and buy a transmitter better than a Talking House that uses a 3 prong power supply as a ground. My station would get out for miles (not feet) and I’d be more than happy to put a big neon sign that says “The Legacy Album Rock A New Radio Revolution owned and operated station Break FREE of the shackles of Top40 and Rap and tune in to a legal part 15 station that Does not Flycast”.

Total posts : 45366Meeting the standards for proof of evidence in both science and court rooms requires information that can somehow be proven by more than someone’s story.
Even witness testimony is unreliable not only because some people lie, but also because the human memory is known to be very faulty.
Even slipperier is a person’s opinion. I am loaded with opinions. Sometimes one of them is right!

Total posts : 45366Thelegacy makes perfect sense.
The Hamilton units use the lightning protection wire and are FCC approved. Either we have some cheerleaders in here or Hamilton products are getting special treatment. There is no mention in the rules that your TX must be at ground level.
follow the 3m rule, use a compliant TX, use proper lightning protection, and don’t give the FCC agent lip if he (ever) shows up. The FCC is more than glad to show off their list of offenders. Unless somebody shows an NAL on a part 15 station over a lightning protection issue, we’re splitting hairs. Even if one is found, I’d like to hear what the operators attitude was towards the agent. We’d either have a case of bad attitude or selective enforcement.

November 20, 2019 at 11:29 am #113289It has even a built in compressor limitter, put some loud music on it an you hear it limits, put some soft modulation and you hear the compressor pumping up the signal.
