Base Amplifiers Are used for house AM and SSB modes can require different features on an amplifier. For instance a SSB amplifier will need a delay while an amplifier for AM does CB amplifiers on the market; however if you intend to use your amplifier for SSB you'll need to look at a couple of other things, such as the aforementioned delay and also the amplifier class. Most AM CB amplifiers tend to be a little "dirty" in terms of their output signal, meaning that there are certain levels of distortion, harmonics, and other unwanted effects. While these are certainly problems (and usually found on class "C" amplifiers) for the AM crowd many of the effects will go unnoticed and aren't a huge concern to those operators. On SSB, however, a "dirty" amplifier can effect how you sound enough that as you use it on the air people may comment negatively about your station, so it's best to buy the Base amplifier for the job.On the topic of AM vs SSB, there is again the issue of input and overdriving your Base amplifier. SSB transmissions don't have a carrier, so in most cases your radio doesn't need any special modifications to transmit on SSB with an amplifier. On AM, however, if your radio has a carrier of 4 watts and the amplifier has input requirements of 2 watts you'll need to lower your radio's carrier. Lowering the carrier of a radio might mean opening up the radio and adjusting a potentiometer on the board, or it might require more drastic modifications using capacitors and resistors, something you might want a CB shop to do.So again these are questions that need to be answered before shelling out dough for a shiny new amplifier.Once you've figured out if your current system is ready for an amplifier and how much power you'd like to run, then the next step is picking the right amplifier for your purposes. jokerman electronics
