KENWOOD TS-520
The TS-520 is a highly sophisticated solid state amateur
radio transceiver employing only three vacuum tubes.
Operating on all amateur bands between 3.5 and 29.7 MHz,
this unit is constructed modularly. All major electronic
circuits are wired on easily removed or installed circuit
boards. The TS-520 includes many built-in features usually
found as extras on other transceivers. Included in the
equipment are a VOX circuit, a 25 kHz crystal calibrator, an
RIT circuit, and an effective noise blanker. The TS-520 also
includes automatic gain control (AGC), automatic level
control (ALC), provisions for break-in CW with sidetone, a
speech processor, and built-in power supplies.
Designed for operation on SSB or CW, the TS-520 delivers
more than 200 watts PEP input. The low power consumption of
the TS-520, resulting from its solid state design, makes the
transceiver ideal for portable and mobile operation. Any
complicated electronic equipment will be damaged if operated
incorrectly, and this transceiver is no exception. Please
read all of the operating instructions before putting the
TS-520 on the air.
