The OM-1700A+ from OM-Power is a lightweight and compact 1700 W class automatic PA that can also be operated remotely. The ceramic tetrode 4CX1500B provides sufficient power on shortwave and 6 m in all situations, whether in SSB, CW or RTTY. A normal transceiver with 40 to 60W transmission power is sufficient to drive it. The PA can be used on all bands from 160 to 6m, including the WARC bands.
The special feature of the OM-1700A+ power amplifier is its fully automatic operation. There is no need to tune the circuits anymore - the PA measures the transmission frequency and adjusts itself automatically. This is done very quickly, in the same band in about 0.5 seconds, when changing bands in about 3 seconds. This fully automatic operation does not even require a CAT connection! But of course, all common HF transceivers can be connected via CAT, further simplifying operation of the station. Another connection can be made via Ethernet to the local network. This makes it possible to monitor and control the power amplifier from a remotely located computer.
Like all OM-Power power amplifiers, the OM-1700A+ is equipped with all the usual safety mechanisms, for example protection against high SWR, filament current or voltage faults, grid current or voltage faults, temperature, opening of the housing and much more. An error memory helps with subsequent diagnosis. The 4.3” color display shows the operating status very clearly at all times. The display also serves as the (only) control element (touch display). The connection to the power supply is via a 230V cable, the power consumption is approx. 3kVA.
Special features of OM-Power OM-1700A+:
- Automatic band switching

- Error memory facilitates diagnosis
- Three selectable cooling modes (two fans)
- QSK-capable transmission/reception switching with vacuum relay
- The power supply transformer can be easily removed for easy transport
- Remote control and monitoring via Ethernet network
