E-1800/A
HF Communications receiver with DSP - this page is a stub

The E-1800/A is a high-end professional HF communications receiver, manufactured around 1994 by AEG Telefunken (later: DASA) 1 in Ulm (Germany), as the successor to the analogue E-1800/3. It is suitable for intercept, direction finding, radio monitoring and other applications.

It is arguably one of the best HF receivers ever manufactured in the previous century. Not only in terms of HF sensitivity, but also in terms of features, flexibility and ease-of-use. It supports a large number of modulation types, some of which are only made possible by the high-end DSP techniques used in the E-1800/A-model.

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

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. Finally, the E-1800/A added full DSP technology to the range and opened up new (digital) modulation types, such as Vestigial Side Band (VSB). It costed DM 100,000 in 1996, which makes it one of the most expensive commercial receivers ever built. The E-1800A was succeeded by the fully digital E-2000 that has no user controls and requires a Windows™ PC.

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.
