General description and the advantages of the OM2500HF Amplifier

The linear amplifier OM2500 HF is designed for all short wave amateur bands from 1.8 till 29 MHz (including WARC – bands ) and all modes .

It is equipped with a ceramic tetrode FU-728F.

Specification of OM2500 HF:

Frequency coverage: amateur bands 1.8 – 29.7 MHz including WARC
Power output: 2500 W in SSB and CW
2000 W in RTTY, AM and FM
