The BLA-703 from RM Italy is a 10-meter (25-30MHz) power amplifier for all operating modes, with an output power of up to 500 watts. The integrated, lightweight switching power supply enables operation with input voltages from 100 to 240 V AC and keeps the total weight of the device at a manageable 13 kg.
The minimum power required for control is just 1 watt; full output power is achieved with an input power of 35 watts. 
A large heat sink integrated into the housing, which is supported by 2 large (but quiet) fans, ensures optimum heat dissipation. 
Easy-to-read LED bar displays on the front of the device provide information about the relative transmission power and the standing wave ratio (SWR) at all times during operation. A switchable receive amplifier enables effective amplification of weaker signals.
The PL/SO239 connections for transceiver and antenna, earth terminal, RCA socket for PTT control and the power supply connection are located on the rear.

The power amplifier offers the following protective functions:
  • Protection against excessive input power
  • Protection against excessive SWR
  • Protection against overtemperature
  • Protection against unwanted out-of-band transmission
