Fine Tune CB

[rabbiporkchop]

In just going to quote this again to confirm you are ignoring my question and just didn't forget about me.

I'm going to take your silence as a sign that were just going to pretend the negative peaks from a Fine Tune cee bee never hit baseline when he speaks into the mic around the 4 minute mark.

His stuff seems to work perfectly with a tone generator but not when you actually talk on the radio. ??????

I've taken measures to make sure my wideband transmitter doesn't do this. Mark needs to get his head in the game.

It's all in your head. I'm not being silent about anything. I do have a job and I do have a life. I'm rarely here. There is no negative Peaks pinching on his oscilloscope. You can't look at a scope while someone is speaking on it and be able to see much useful information.
When he injects a tone into it everything is perfect. When he cranks that tone up to 4000 Hertz or down to 100 Hertz it's perfect. That's all you need to know.

Apparently you aren't well versed in acoustics. There's a little app that you can download to your smartphone to show you what frequency every sound generates.
The the hissing sound at the end of the letter s is approximately 5300 Hertz. That sound is the only thing that differentiates the letter s from the letter f. I'm sure you can imagine the confusion when someone ask you to repeat yourself because they were unable to interpret what you said based on your limited frequency response and the inability to differentiate between those two letters.

Keep in mind vocal cords are not used to make that sound so the frequency is the same regardless of whether it's spoken by a 2 year old child or a 50 year old man

i since retired from tech work. the eyes are not what they used to be.

Mark is a meticulous tech, ( I like his work) although he can not and will NEVER be able to defy physics. His work/tuneups cannot defy physics, either. Some of the claims on this thread regarding the guaranteed distance 24/7 on 11m unconditionally- is laughable. If there was a BS meter here- it would have went off the scale and exploded in a fiery blaze. Thanks for the entertainment.

It's only laughable because you haven't experienced it and you think it's impossible. The funny thing is if you were sitting next to me I can prove it to you and you would stop laughing. What part of the country do you live in? I can introduce you to some people that would blow your mind about what their stations are capable of doing 7 days a week regardless of what Mother Nature throws at them. Keep in mind there's probably thousands of others capable of the same thing but I only know two of them personally.

Yes the 80-mile trip was a one way trip.
Yes it can be done 7 days a week verified by a phone call on the other end.
Yes those hundred and thirty-five mile trips are done with massive amounts of power but only verticals and no beams.

funny thing is i never even heard of this fine tune shop. until reading this thread.

Perhaps not so well in acoustics of speech but infinitely better versed in electronics than you could imagine. The sounds of the SSSSS will sound different between the two year old and the 50 year old. What I was originally trying to point out is that your claims of ridiculous ranges and distance is due to the tuning of the radio. Not so if they are running a truck load of power. Then the radio is pretty much irrelevant with kilowatts of power.
If your technician can pass the current Extra class exam for amateur radio I will talk to him about buying my radios from him.

Or the General RadioTelephone Operators License (which would give the legality to adjust radios).

You are full of BS and the fine tune kool-aid. I still see bright horizontal lines at baseline while he is speaking. Why is that?

This only happens on my scope after the REA modulation monitor shows 100% negative peaks and I turn the audio up a bit more. Maybe I haven't worked on enough radios for truckers to know what I'm talking about.

Mark takes your money, uses you as a puppet and makes you look foolish. Great tech... Baffle me with some more technical mumbo-jumbo.


On a side note about the extra exam. I passed mine. A friend of mine did it in elementary school...they required code back then. Just because a tech has an ameatur license doesn't make him worth anything.

After meeting the guy and listening to all his long winded B.S.(and this guy will talk your ear off even when you're walking out the door trying to leave). I doubt he would ever get a FCC license. He doesn't even have a business license. He operates out of his trailer home and regularly moves it around the country.

I sense from him he feels intimidated by hams yet I have seen some of the sources of information he learns from are written by hams.

He is really a radio repair and tweak shop not a radio dealer.

If you haven't done so already, read my post on page 1 of this thread to get my perspective of my encounter with him.

 

[543_Dallas]

Speaking of tweak shop is he really a meth addict or was that just a rumor?

I wont' say, but did my last post hint at it or was I just using the word tweak as a metaphor?

I've heard that rumor from a couple of different people. Your choice of the word tweak just spiked my curiosity.

The new Extra is considerably more complicated these days. I studied the old question pool and had no problems with it at all. Now I have to read and reread the question to verify what it is they are asking. What you say is true an amateur license is a license to be an amateur!

I took mine around the first of the year. I haven't looked at a practice exam since the test changed a couple of months ago.

I took my tech, general, and tried the extra missed extra by just one question. I did not study for that level at all. I Aced Technician, missed only one on the General.
Started studying for Extra just before the question pool changed and could not find a test close enough before the change. Now I am studying for the extra and the VERBIAGE has changed and it is a bit tricky. I will have my Extra before Summers end. Just waiting for a testing date.
