Note: The amplifier VHF111 is an apparatus born to offer new possibilities to the possessor of VHF "handheld" transceivers.
Although VHF is formed by two stages in cascade. It has surprising linearity features which allow a perfect use of it in SSB too.
This amplifier offers a notable gain and it is particularly attended in the harmonics content (-50dB).
Because of the great diffusion of the VHF handheld transceivers, VHF111 is very interesting for the most part of OM operating in that band. Certainly you'll have more satisfaction with the help of VHF111 !
