RM Shortwave Power Amplifiers 150/300Watt
Compact and handy linear power amplifiers for all HF bands from 1.8 to 30MHz, with approx. 150 or 300W output power. These amplifiers work real linear amplifiers and not as a C class device, as many simple CB type amps do.
A special feature the amplifiers have a six-way output low-pass filter, which is switched automatically by micro processor. Additionally this filter can be switched manually (e.g. when receiving).
The relative output power is shown on a bar graph on the front panel. The amplifiers have a protection circuit against high SWR. Transmit/Receive switching can be done either be HF Vox or a PTT cable.
The controls on the front panel allow a selection of the Vox hold time, additionally a 3dB input attenuator can be selected, which reduces the amplification by about 50%.
Connectors: IN/OUT 2x PL, PTT: cinch socket, active low.
The model HLA-150V-Plus has two temperature controlled fans, good for continous operation. The model HLA-300V-Plus has these fans as a standard feature. On high frequencies the output power is slightly reduced,
the model HLA-300V-Plus reaches approx. 250W.
