A little help please
Just a couple of quick questions and I apologise if this has been asked before. I did a quick search but came up blank.
I'm looking at getting an amplifier for my radio but would like to know a little more about them.
Does a straight amplifier only boost your output signal and to increase both input and output do I need to get an amplifier with preamp?
Also all the amp's I see advertised seem to be rated 1-5watts for AM/FM and 1-10watts for SSB input but I see everybody saying you should turn your radios output to 2watts is this really required if your within the limits for the amp's input?
And lastly are mosfet transistors better than MRF transistors when looking at amp's.
