The SDRplay (RSPduo) is a dual tuner, broadband SDR, which receives all frequencies from 1 kHz to 2GHz. It is particularly interesting that a frequency range of up to 10MHz can be displayed and thus does not lose track of the tape. Certainly very interesting at the contest to locate new stations faster.
The RSPduo has 2 antenna inputs (SMA sockets) in 50 Ohm technology. A third high-resistance antenna input (sym./unsym.) Is also available, for example to receive stations in the LW/MW/KW range with a simple wire.
As an antenna, I have a T2FT−antenna and am able to receive the entire MW and KW range up to and including the FM radio band (all stations in STEREO!). The high sensitivity of the RSPduo means that there is hardly any difference in reception to my Optibeam between 14-30MHz! But the DBZ40 also only brings max. 1−2 S−steps more than the T2FT−antenna.
In the evenings I could not find any intermodulations or other problems with very strong shortwave stations, sometimes with signals of over 59 + 40db. In my view, the dynamic range of the RSPduo is excellent!
As software, I only use the SDR Console V3, which seems very tidy and functional to me.
Finally, I would like to briefly mention that the RSPduo also has a reference I/O, which allows, for example, synchronization via GPS signal or the synchronization of other RSP devices.
All that is required for operation is a PC and an antenna. The excellent functionality of this really good communication receiver convinced me.
For everyone who has been using an SDR stick so far, it should be said that this SDR is absolutely not comparable! Test it yourself!
