Using Exalted Carrier Single Sideband

This technique (often abbreviated ECSS) depends on the receiver's selectivity as well as being able to select one sideband or the other. Either using the BFO or a synchronous detector, you tune away from the interference by selecting one sideband or the other. You would then use other controls (like the passband control found on the Drake radios) along with notches to remove any remaining hetrodynes. Properly doing this can really clean up a signal. Tuning like this can be reported as ECSS-U if you were listening on the upper sideband, or ECSS-L if listening on the lower.

Note that another definition of ECSS is Exalted Carrier Single Signal.

Are there any radios that can do this today?

Portables like the Tecsun PL-660 and 680 are reported to be very good at ECSS. But to see radios that had this capability that worked well, we must look in the past.


The king of ECSS capable radios in the portable world is the long-discontinued Sony ICF-2010 (also known as the ICF-2001D in some parts of the world). The Sony ICF-7600G was also very good. For portatops (radios that marry the characteristics of a desktop with a portable) the Eton E1 (and its cousin the E1XM) also performed well. This is to be expected, as the E1 was a joint venture between Eton/Grundig and R.L.Drake. In fact the E1 was serviced by Drake engineers at one point. The later editions of the Drake SW8 and SW8A also had this capability.


In the desktop world, the Drake R8 series (particularly the R8 and R8B - the R8A's performance on ECSS was rated not as good as the older R8), the AOR-7030 and some of the Japan Radio Company radios (the NRD-535 and 545) all have this capability.


In the world of Software Defined Radios (SDRs) the following applications are known to support Sync AM and/or ECSS. If there are others not listed here please feel free to add them;
