Pre-amp for the SSB receiver - boost the selectivity and sensitivity of your SSB.

However this is only partially true. After all the SSB receiver already has an exceptional signal-to-noise ratio (0.15 pV at 10 dB). Nevertheless the RF preamp does supply an extra 10 dBs, which, you must agree is useful and in some cases desirable. This im- provement in sensitivity is certainly going to be welcomed by SSB owners with a small or compact aerial. Apart from the better selectivity and sensitivity, this RF stage supplies additional gain in order to overcome some of the traditional SSB problems. pre-amp for the SSB receiver boost the selectivity and sensitivity of your SSB. is harder than standing on the beach and trying to stop the tide.
