This series of amplifiers is designed for 143 to 149 Mhz 2
meter band operation. The designs use the latest in
micro-stripline techniques and highest quality state of the
art transistors. Relay switching is automatic RF sensing.
These units do not require any tuning. The boardband design
offers the ultimate in flat input VSWR, 1.4:1 or less, and
produces rated power output or better across the entire two
meter band. This amplifier can be used for AM or SSB
operation as well as FM and CW.
The front panel switch on all models switches the amplifier
in or out. With the switch “in”, the 13.5 VDC is supplied to
the RF sensing and relay 'circuit inside the amplifier,
however, the unit will not draw any current until the
transceiver or transmitter.is keyed and RF is applied to the
amplifier. At this point an audible click of the relay can
be heard and the LED light on the front panel will light.
The amplifier will now amplify the RF applied. In the “out”
position, the amplifier will bypass the RF through the
