[Premium-Rx] For sale: Rohde & Schwarz EK 891 shortwave receiver

[Heinz Breuer]

Hello Ed,

here is what specs I described in my Premium-RX ad:
——————————————————————
I have a Rohde & Schwarz EK 891 shortwave receiver for sale. The 19“ full wide EK 891 and it’s brother the half wide EK 890 are analog shortwave receivers, which are almost identical. The 19“ full wide EK 891 has an added internal speaker and a decimal keypad as well as a keypad to select modes and other functions while the EK 890 due to limited space on the front panel is not as easy to operate and requires several clicks in the menue.

The EK 891 offered is the variant 37 with following bandwidth: 100 Hz, 300 Hz, 600 Hz, 1.5 kHz, 2.4 kHz and 10 kHz with the roofing filter at the first IF.

The installed filters are common OEM 1.44 MHz crystal filters. 
The EK 891 is equipped with the optional GM890 signal processor which offers DSP functions.

An English datasheet is available on the www.kongsfjord.no website. On the left select data sheets, select Rohde & Schwarz, click onto EK 890 family data sheet.

There is a 1.44 MHz IF output and also a programmable 10 kHz … 50 kHz output of the installed option GM 890 on the rear. The signal could be further processed by a Sound Card or DSP receiver. I can’t say more about it as I am not into this kind of stuff.
