1. Introduction
RGO ONE is classic superheterodyne down conversion HAM transceiver covering all
HF bands 1.8 - 29.7MHz (160/60m as an option). Due to its modular construction it

4. Installation
4.1. General
Choose an operating location that is dry and cool. Allow adequate ventilation around
the heat sink on the rear panel and sides of the transceiver.
For normal intermittent transmission, such as casual SSB or CW, natural convection
cooling is all that is required. When transmitting for long period of time and with
high duty cycle, such as in digi modes, it is recommended optional fan cradle to be
installed onto the rear heat sink.
4.2. Connections
4.2.1. Power requirements
Stabilized power supply of 12-14V DC capable of supplying 12A, negative ground is
required. Battery operation: RGO ONE can work on battery, when the voltage does
not fall bellow 11V.
4.2.2. Antenna
Any matched 50 ohm unbalanced antenna can be used with RGO ONE. Antennas
with open end or random length wire antennas will require matching system or/and
good grounding or placing good counterpoises otherwise stray RF energy and/or poor
SWR may damage the equipment. Placing proper BALUN between antenna and the
feeder is highly recommended (fig.3).
