The OM2000A+ is a fully automatic HF and 6m linear amplifier covering all amateur bands 1.8-54Mhz

Utilising a single FU-728F ceramic tetrode the OM2000A is designed for high power continuous duty.

Specification of OM2000A+:

Frequency coverage: Amateur bands 1.8 – 29.7 MHz including WARC + 50-54 MHz
Power output: 2000+ W in SSB/CW on HF bands, 1500 W in RTTY
1500 W CW/SSB on 50 MHz
Drive power: 40 to 60 W for full output power
Input impedance: 50 Ohm VSWR < 1.5 : 1
Output amplification: 17 dB
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: better then -32 dBc
Suppression of harmonics: min -50 dBc (30–54 MHz better than -70dBc)
Response speed of AUTO tune: less than 0,5s within same BAND ,less than 3s if out of BAND
Icom transceive protocol using by microHAM devices – CI-V OUPUT,
Flex Radios and Anan ( Apache Labs )
Tube: FU-728F ceramic tetrode
Cooling: Centrifugal blower + axial blower
Power supply: Switchable 220,230,240V – 50/60 Hz or other primary voltages
(for example 200V 50/60Hz for Japan)
Transformers: 1 toroidal transformer 3.0 kVA
Protection circuits: – VSWR too high
