General description of the OM2000+ HF and 50 MHz Amplifier
The OM Power model OM2000+ is designed for all shortwave amateur bands from 1.8 to 29.7 MHz (including WARC bands) + 50 MHz and all modes. It is equipped with a ceramic tetrode FU-728F.
Specification of OM2000+:
| Frequency coverage: | Amateur bands 1.8 – 29.7 MHz including WARC + 50 MHz |
| Power output: | 2000 W in SSB/CW on HF bands, 1500 W in CW/SSB on 50 MHz, 1200 W in RTTY and DIGI modes (800 W on 50 MHz) |
| Input power: | Usually 40 to 60 W for full output power (USA model), 20 to 30 W (World gain model) |
| Input impedance: | 50 Ohm, VSWR < 1.5 : 1 |
| Power Gain: | 15 dB (USA model), 17 - 18 dB (World gain model) |
| Output impedance: | 50 Ohm unbalanced |
| Maximum output SWR: | 3:1 |
| SWR protection: | Automatic switching to STBY when reflected power is 350W or higher |
| Intermodulation distortion: | -32 dB below nominal output |
| Suppression of harmonics: | < -50 dBc on HF, < -70dBc on 50 MHz |
| Tube: | 1x FU-728F ceramic tetrode |
| Cooling: | Centrifugal blower + axial blower (external) |
