Simple answer...get the Amplifier...The largest one you can get...

You will not see to many Ham buy an Amplifier simply to sell it later on (There are some cases)

I use the AMP, it just saves the hassle time..And one can have a QSO..I hear all the time, only 2 S Units..(That is assuming each S UNIT is 6dB)...Well, 2 S Units is very good! (And by the way, next time you hear a Ham operator with an Amplifier (Legal Limit) ask him (Or her) to turn off the amp, you will see more than 2 S units I assure you...There are many reasons for this, one of them, is the fact that not all S Units are calibrated by 6dB...

On the other hand I love digital, and yes with only 30 to 50 watts you can work the world!

See you all on the bands...NN2X  / Tom

Tom is correct there. If you cannot make contact 50 watts or less, PSK-31 for instance,
something is seriously wrong at your end and an amplifier isn't the cure. Get a quality
antenna up first then put some meat behind it.

Tom

Your call is familiar. PSK-31, 14.070MHz?

And I'm adding two more FETs to my EB-104 for an additional

(raise your pinky to your mouth like Dr. Evil) 300 watts.

I'll add another pass transistor to an Astron RS-20 for the additional
current capability.

Don't worry, they'll be evil FETs.

In my case I live in Brooklyn NY and really don't have space for a tower and beam. I'm also getting to the age where I wouldn't want to maintain them. But an old SB200 putting out 500-600 watts into a Alpha Delta DX‑EE, gives me just enough boost to be heard in a pile-up. More power than that would be an RF exposure and RFI problem to the attached homes on either side of our house.

Mr. K0UA,

How's that Brand! New! Ameritron AL-80B amplifier treating you?

You've had over two weeks to make up your mind. Maybe you're
a woman and need the normal day and a half?

Or did you follow the 'sane' path to like me to an EB-104 four-FET amplifier.

No amp yet Krause.  Although those SPE solid state jobs sure look good.

Yikes, the price tag! Wheew!

I'll keep with my EB-104. I add two more FETs this weekend.

I have extra strong eye protection to stave off any you know whats.

Ain't nothing wrong with a low cost Ameritron ALS-600.

There is a gentleman I just sold my AL-800H too that might be selling his AL-80b any day now so I would keep an eye out for an AL-80b coming on the for sale forums one day soon.

    Do I need an amplifier?

     If you can hear them but they can not hear you. First you ask if it is practical to improve your antenna from a room, cost and effort standpoint. Great improvement can be made to a very poor antenna with little effort or money, “IF” room permits. Often this corrects the problem. If it does not. You need an amplifier.

   If you have the best antenna that is practical. In your situation and are still not heard. You need an amplifier.

    Are you competing in any way? If in a contest. You need an amplifier.

     If you are working gray line propagation and conditions are fading. An amplifier often allows a QSO to be completed that might not be without an amplifier.

    If you are at or near the noise level. If a comfortable QSO can not be maintained while others have no issues. 

     If you are being squeezed by stronger stations that just don’t care about a week station 1 KC away when they decide they want the frequency.

    If you can afford it and the associated cost of running a station setup that will safely handle the extra strain at the desired power level.

   Remember that if is the middle word in life. If it fits your needs and budget. You need an amplifier.

If I am marketing amplifiers for a living you need several amplifiers.

I use a amp a lot on 40m during day. Between daytime absorption and atmospheric noise, 10 db can help a lot when stretching range and having a solid copy still. There are many day time QSO's on 40 m that I would have never had or would of been a lot less pleasant without a amp on both ends. I rarely use a amp on 20m and above though.

That's only if the RS-20 power transformer can handle the extra current.
