Pilsner - the problem is that you have a radio and Amp that really shouldn't be run together.

 

Can you make an S9 do less than 20 watts on SSB? YES, but it goes against all properties of what that radio was meant to do.

 

You can't put a V8 engine inside a toyota tercel. Maybe you could with a ton of modifications, but by the time you do all the mods what the hell was the point in buying the V8 engine?

 

The radio needs an 2 x 2290 or 2 x 2879 or even a straight 4 x 1446 amplifier.

 

I've run exports doing 30 watts SSB into a 2 x 1446 without problems, but you have to know what the amp can handle and what your radio is doing for output.

 

The Magnum S-9 is a great radio - what is the point in detuning a great radio to run with that amplifier?

 

If you want to get the full worth of that radio buy a proper amplifier to match up with it.

 

Otherwise buy a SSB single final radio that only does 12 watts SSB that will match up with that amplifier if you insist on using it.
