HF amplifiers from 150/300
Compact linear amplifiers and handy for all HF bands from 1.8 to 30 MHz with output power of around 150 or 300 Watts. These amplifiers do not operate in class C as do many amplifiers CB. One feature that distinguishes them is the low-pass filter 6-way output, switched automatically by a microprocessor. These filters can be switched manually (b.a. in reception).
The power output is shown by a LED on the front panel. The amps are protected against ROS. Transmit/receive switching can occur through VOX or PTT line. The front panel controls allow selection of the time restraint of VOX and you can insert an attenuator 3 dB input that reduces the amplification of 50%.
Connectors: 2 x PL, PTT IN/OUT: cinch, active low.
The modell HLA-150V-Plus has two temperature controlled fan, ideal for continuous use. HLA-300V-Plus model has three fans. On high frequencies, the power is slightly reduced, the HLA-300V-Plus model reaches about 250 W.
