HF Communications receiver - this page is a stub

The E-1800/3 is a high-end professional HF communications receiver, manufactured around 1985 by AEG Telefunken (later: DASA) 1 in Ulm (Germany), as the successor to the analogue E-1700 range. It is suitable for intercept, direction finding, radio monitoring and other applications.

For a long time, the E-1800/3 was arguably the best HF receiver in the world, and its impressive specifications were only countered by the DSP-based E-1800/A and by the ICOM IC-R9500.

This page currently acts as a placeholder for future information about this receiver.

The E-1800/3 is part of a family of devices of which certain components could be mixed between models. It is therefore possible that certain plug-in units have model numbers in the range 17xx, but also in the range 19xx. The complete series consisted of the E-1700, E-1800 and E-1900.

The first (analogue) E-1800 model was introduced in 1985 and was considered in many reviews as one of the best receivers ever produced. It was followed by the E-1800/3 that had a much improved front end. In 1994, the range was completed by the E-1800/A, which adds DSP signal processing to the design, and offers (optional) modulation types like QPSK and pulse modulation.

The VHF/UHF variant of the E-1800/3 is known as the E-1900/3. It has a frequency range from 20 to 1000 MHz. It share the same accessories and some of the plug-in modules of the E-1800.

Panoramic display   PSG-1800
For a visual inspection of the frequency spectrum around an intercepted signal, it is possible to connect the PSG-1800 panaramic display to the IF output of the E-1800 receiver.

The device features a crisp and clear EL Display and can be used to view the spectrum from two receivers simultaneously.

Radio modem with FEC   ETM-1800
ETM-1800 was the first generation of high-end HF modems with advanced error-correcting features like Forward Error Correction (FEC) and ech-cancelling. It was developed in the early 1980s and is housed in a 3U 19" rackmountable enclosure, similar to the case of the E-1800.

Radio modem with FEC   ETM-1810
ETM-1810 is a high-end HF radio modem with advanced error-correcting features like Forward Error Correction FEC) and echo-cancelling, housed in a 1U 19" rackmountable enclosure.

The ETM-1810 was introduced in 1985 and is the successor to the ETM-1800 listed above. It was commpnly used in combination with the ARCOTEL ACT-1810 data processor, and is often found as part of FARCOS, MAHRS and HF-7000 special-forces systems.

Radio modem with FEC   ETM-1820
The ETM-1820 is the successor to the ETM-1810 (featured above). It features a 2-line LCD display and has some additional controls, but is otherwise functionally identical.

The ETM-1820 supports many civil and military communications standards and protocols, most of which are soft-loaded and can be ordered as an option.
