Baffled by the range claims

This isn't how it works with the ISS, it is an orbiting object and height in relation to the earth while in orbit is different than height in relation to two terrestrial objects.

You can't use a 5 watt handheld with a vertical antenna while the ISS is in sight, you have to wait until it is overhead and this has to do with two major things, one is the polarization of the antennas and the losses of the signal - the latter is corrected by using a directional antenna.

By the way, it is recommended you use 25 or more watts when talking to the ISS.

 

From the first link:

From the 2nd link:

No, my links don't support my opinion! LOL

You have to actually READ the links.

And 27mhz is 27mhz. Even in ideal conditions such as in a boat over water, they STILL say it's line of sight and limited range. You apparently don't know much about radio waves if you think they bounce off the ground LOL They bounce of the ionsphere you moron. You really should read up on how radio waves propagate! You're really making yourself out to be a looney.

Why can't you just admit you're wrong? I'm a licensed Ham radio operator. I've operated down to 1.8mhz before. THAT is not line of sight. 27mhz is.

 

Just correcting someone who thinks they know what they're talking about and they don't. I don't want someone buying a radio and thinking what this guy is saying is true because he's clueless. He's basing very rare instances of ionic bounce and saying that's what CB is normally capable of. It's not, its line of sight with very few exceptions. There are exceptions but they are very rare and should not be relied upon.

I have radios installed on every vehicle I own, my boat, every boat my parents own at their camp (4 of them) a radio on my 4 wheeler, one I had installed on my motorcycle until I was run over by a woman at a stop light and it got busted up, and I even have handie talkies that I carry with me sometimes. I'm a member of the ARES net where I live (emergency response radio relay).

I've been into radio since I was 17 and a HAM operator for 11 years. I do want to quantify my experience so people know I'm not just hot air.

 

Correcting someone by calling them names isn't the way to go about it. Just present your facts and let them decide if they are right or wrong. If they are wrong, surely they will admit it and thank you for showing them the light. Plus you gain a friend.

 

There’s not a perfect definition for defining “distance” in this instance.

And conditions other than topographical can alter the thing.

Maybe it’s easier to say what we all of us already understand: CB is limited for distance.

I like, and use, X-air miles. (To let a new guy know it’s “different” than Point A to B. Some get it).

FWIW, Brandon, I’m past age 60 and RL had his first Amateur cert before I was born. I’ve found his posts to be consistent on the subject. Whether I agree or disagree.

I don’t think you’re blowing hot air, and I think it really does matter that for truck drivers, practical advice is important. So keep on with the experience and education, please.

But it’s a real short ledge to stand on for all of us as to agreement.

Exceptions start REAL quick.

A guy comes in and wants advice. But there “ought to be” a questionnaire as to what he does, how he does it, and what does he expect? And for how much?

Plenty of guys would be lost right there. No basis for comparison.

Love it. We can agree you know some things but not everything. Too bad you are set on using a term incorrectly.

Yes I read them and no they don't support your position. They make the statement but nothing really to back it up in relation to the subject of terrestrial radio.

The first one is a FAQ, nothing in there that has any bearing on the real issue, it touches on the subject with a generality that has been wrong for a long time.

The second one as I said applies to water and a boat, the signal has no earth to follow just water.

AND yes I do know what that means.

OK limited range I can agree with that, it is set at 15 miles but line of sight - no.

Moron?

Looney?

Did I call you one?

Oh wow, I am the one who doesn't know much here?

I think they bounce off the ground, really?

Wonder what kind of rubber they use in the wave?

Do you know what surface wave propagation is?

Did anyone ever teach you how to calculate the power density of a wave and how wave attenuation effects surface wave propagation in a upper HF fixed location?

I'm thinking you don't even understand the magnetic force relationship to the electrical force of a wave.

Or how everything works with a mobile unit.

Oh you brought up a big word - ionosphere.

What in the world does that mean?

That is used for long distance communications, not for local communications.

You missed the boat there fred.

Yeah that was a word I learned in 1960's, I also learned a lot of others things and terms ... like Troposphere scatter, refraction, difference between a space wave and a surface or ground wave, phase related local propagation and a bunch of others that I don't think YOU have a clue about.

How about you cracking a book on radio theory yourself.

I know how they work, thank you very much.

AND?

What?

Let me guess, you hold a general ticket?

AM I supposed to be impressed here?

So tell me something I don't know.

Here is my what backs my little bit of knowledge - Extra ticket holder, GROL holder (grandfathered in by holding a first class), earned my MSEE (actually it is called an MEng/EE) and my last "internship" at BBC One before I went to work at a local radio station.

I don't know everything but I do know a lot more than most and as some old man I met said about a lot of people he met "I forgotten more than most know" - Bill Orr W6SAI. I do like to banter with people like you, no hard feelings at all.

Really Slow, I didn't get my ticket in 1850. Please

I'm just a little older than you, I remember Truman and saw Kennedy when he was in Detroit campaigning.

 

What's funny is 2 pages ago you promised links proving me wrong. I've yet to see one. I provided multiple links from different sources. You? Nothing.

Mic drop. Case closed. C ya.

 

I promised links?

Where?

I just looked, no links promised.

You provided little in explaining what's what, all you did is say here is a link and it proves I'm right.

No case closed

Sorry dude, go back to school.

By the way what ticket do you hold?

 

I like using the Indo Distance Calculator which shows “as the crow flies” distance and elevation. When you see someone bragging about talking 39 miles on SSB, you can go verify that you can talk twice that far on AM and that they shouldn’t necessarily be bragging. It comes in handy.
