General description and the advantages of the OM3006+ Amplifier

The linear amplifier OM3006+ is designed for 50 MHz amateur bands from 50 till 52 MHz and all modes. It is fitted with a ceramic tetrode GU78b.

In addition, this amplifier can be equipped with enhanced IO box and can therefore be remotely controlled, thanks to LAN port and adapted firmware.

Specification of OM3006+ :

Power output: 3000 W in SSB and CW, RTTY, AM and FM
Driver Power: usually 40 to 60 W for full Output Power
Input impedance: 50 Ohm, VSWR < 1.5 : 1
Power Gain: 17 dB
Output impedance: 50 Ohm unbalanced
Maximum output SWR: 2:1
SWR protection: Automatic switching to STBY when reflected power is 350W or higher
Intermodulation distortion: 32 dB below nominal output
Suppression of harmonics: < -70 dBc
Tube: GU78B ceramic tetrode
Cooler: Centrifugal blower + Axial blower
Power supply: switchable voltages - 220/230/240V for 50Hz or 230/240/250V for 60Hz
(or other primary voltages e.g. 200V 50/60Hz for Japan)
Transformers: 2 pcs of toroidal transformer 2.5 kVA
Parameters: 485 x 200 x 455mm (width x height x depth)
Weight: 32 kg
Protection circuits: - VSWR too high

  - Soft start for protecting your fuses
  - “switch-on blocking“ at opened amplifier
Indications: 4.3" color touch screen display
Features: High level of protection
  Memory for faults and warnings, easy maintenance
  Automatic set-up anode current (BIAS) – no need to manually adjust after changing the tube
  Three programmable working modes of the axial blower
  Full QSK operation
  Many operational parameters to display
Option: REMOTE control - connector for LAN connection – remote control software free of charge

LAN Connection (only for model with remote control option)

Power amplifier is interfaced to LAN via XPORT made by Lantronix (type XP1001000-05R). More info can be found at www.lantronix.com .

Default factory settings of XPORT are:

IP address:

These are strictly default settings. You can modify any of these by going to XPORT web GUI via your web browser. We do not recommend changing any other parameters of the XPORT interface as loss of communication can be caused by doing so. Default settings haven’t username or password. It is highly recommended to secure web interface with username and password.

For remote control and monitoring over LAN special software is needed. It is available free of charge; it can be downloaded from the following link: Remote control software version 3.38.

NOTE: For the correct functioning of the software, it is necessary to have accessible LAN ports 9999 and 10001.
