Introduction
On behalf of our development team, we want to thank you for choosing the TX-500 Discovery.
The TX-500 is an ultra compact all-mode transceiver ideal for travelling. Its compact size
and weight mean that you can take the instrument to remarkable places, where radio work
will give you an unforgettable experience.
The strong casing, protection against splashes and dust ensure the use of TX-500 in extreme
conditions and guarantee its reliability. A sharp monochrome display will allow you to clearly
see the information in either bright sunshine or low light, thanks to a multi-mode backlight.
The transceiver parameters and functions will also make it possible to successfully use the
unit at a home station or as a mobile version. Record-low current consumption in reception
mode (up to 110 mA) will extend the battery life, providing for longer stay on the air without
recharging.
Because the TX-500 is a software-dened radio (SDR), you can expand its capabilities using
computer applications and adding new features with free rmware updates. The TX-500
Discovery has an integrated high-performance spectrum analyzer, allowing you to see
signals before you hear them.
It’s high time to go off into the deep blue yonder, taking the TX-500 with you.

Protections
OVERVOLTAGE PROTECTION
When exceeding 15.0 volts, the transceiver won’t allow switching to TX mode, (the voltage
indicator on the display will become inverse) a signicant excess (more than 16 volts) it can
cause the protective fuse to burn out, as well as the failure of the transceiver! Use a power
source or battery with a voltage of 9 to 15 volts and a current of at least 3 Amps.
AATTENTION! Exceeding the supply voltage above 15 volts can damage
the transceiver!
REVERSE POLARITY PROTECTION
If you connected a minus voltage source or battery instead of a plus, the transceiver will not
turn on. You must connect the external power supply correctly, please, see the pinout of the
power connector in the section “Controls end user interface”.
OVERHEAT PROTECTION
The transceiver has an internal protection against the overheating of the output stage of the
transmitter. If the TX continuous mode is too long, the output stage as well as the transceiver
body can be heated up. If the limit value is exceeded (about 60 degrees Celsius), the trans-
ceiver won’t allow switching to TX mode. After the temperature drops, the TX prohibition
mode will turn off automatically.
AATTENTION! During long-term TX mode (digital modes) do not block the air
access to the rear cover of the transceiver, or reduce the power.
TIP: Unfold both rear legs to increase the air flow convection.
