A 1 megawatt amplifier will not make a difference if propagation sucks.

However, what I have learned from using amplifiers, is that a bigger signal = being heard better. Thats about the only reason. Remember an amplifier is not for you. It is for others. You are literally spending your money to please others. Plus it is pleasing when people actually want to talk to you because they can hear you above the noise.

There really is no justification for an amplifier unless you want to be kind to other operators and reduce their having to struggle to hear you. Ultimately that is the ONLY use for an amplifier.

If you know that you are not too worried about big power and just want to be heard on the noisiest nights then get a lesser expensive AL-811 or Al-80b or Als-600 and it will be More than enough.

I run an ALS-1306 and I have just sold my AL-800H. I am going to get an AL-82 if I get another amplifier for legal limit. the 1306 will do 1200 watts without flinching and it is 100% more than I need to get 20/9's left and right.

This post is spot on.  An amplifier is all about making it easier for the other party to copy you, and ultimately increases your rag chewing pleasure.

One of the biggest differences i found on 6m was antenna i went from a home brew/ diamond 4 element to a precision yu7ef 5 element boom was 1.5 m longer but the difference was huge. if you can get to a 5 or 6 element yagi you will be surprised height makes a difference as well but your height seems ok. amps can make a huge difference and save hours calling in a pile up. i will say one thing get the most powerful amp you can afford. then when you bust a big pile up first or second call  take a picture of your smile it will be priceless then you will understand why they help so much.

It's all about the antenna. I went from a low wire antenna most of my ham career to a hex beam at 45 ft. It was like hitting a light switch. I added an amp and I was a big gun. I had never worked japan. With that set up, on cw, I would get on 15 meters about 6 pm in the winter and work them one after another. It was marginal, but I did it.

Got bored with it all and sold all that. Now I'm with a ts 520 and an amp and wire antenna.

i find the amp makes a tremendous difference on ssb. You can have a 600 watts and it will make your audio so much better for the guy on the other end.

Getting out there is always about the antenna you're using.  But, if you're doing the very best you can with an antenna - due to space, or restrictions or obstacles or just about anything else except cost - then an amplifier is your next choice.

Sometimes I wonder why folks would spend several thousands of dollars on an amplifier without first making even half that investment into a really awesome antenna.  But they do!

Raise your antenna. Heck, build one of Communications Concepts amplifier. Fancy it up to your
liking. I use the EB-104 600 watt amplifier. I'm condsidering adding two more FETs for another 300
watts.

Ham radio is about building, erecting, fixing.

Have fun.

Why do people want a big roaring V8 in their car when a V6 or 4 cylinder will do? It's all in what you want to do!

Mike,

That's different. My F-150 gets about 13 miles per gallon. Someone brags their vehicle
gets 25 miles per gallon. I tell them I got you beat. It confuses the heck out of them.

This thread is going around in circles.

Young fellow, get an amplifier. You don't have to use all of it.

Have fun in the meantime.

You only need one reason to have more power.
What do you like to do the most?
An example:
This weekend is the VHF contest.
The bigger signals get heard, you wait till last if they don't move frequency and hope your heard.
Bigger higher antennas are not always the substitute but they help.
Once you get left behind enough times from lack of enough power, you will see the nonsense of one S unit for doubling power is not enough  reason to abandon the idea.
Again, depends on what corner of the hobby you want to play in.
Another example on 6m where there is a big difference between Tropo and sky wave communications.
Good luck.

So that the point of contests? I sure don't get it.

I'm on 18.087MHz, CW. Lots of hot ham radio traffic to process.

Kraus, there is more to life than 18.087Mhz CW.  You will just have to trust me on this one.  Smiley

One way to work much more dx on 6m is to use cw. Much better than trying to use ssb under weak or good conditions. The last time I was on 6,I heard more people on cw then ssb. I hope that continues.

A long time ago an old timer told me that running an amp made him feel better.  That in itself should be a good enough reason.
