SDRPLAY RSP1A User manual
What is an SDR (Software Defined Radio)
Receiver?
www.sdrplay.com
A radio receiver where much of what
traditionally was done in hardware,
is now done in software.
The SDRplay RSP1A hardware does up-front
filtering, amplifying, mixing and Analog to
Digital conversion.
It sends the digitised signal to the PC over the
USB cable and the SDRuno software performs
the rest of processing chain

The SDRplay RSP1A is a powerful wideband SDR
which covers the RF spectrum from 1kHz to 2GHz. All
it needs is aPC and an antenna to provide excellent
communications receiver functionality.
USB cable*
Ideally outside
and at least
4m above
ground
Wire antenna, >10m long
for shortwave
Download SDRuno software
from SDRplay website

Allow Windows to install if you get a message saying that Windows can’t verify the publisher
When you get the message below, wait 30 seconds and then plug in your RSP1A and click
“Next”
Click on “Finish” and SDRuno will launch – lots of windows will automatically appear and arrange
themselves on your PC screen (accept these defaults for now)

Connecting another length or wire to the outer of the coax allows you to ground the unit which
will further improve the signal strength. This can be connected to the house-wiring ground, a
metal radiator system, a grounding rod or even a metal window frame to act as a “counterpoise”
Tape the connections carefully. For a more permanent solution we recommend buying
connectors or lengths of coax cable to connect from your RSP1A to a convenient point near the
outside world. Additional matching devices may further improve reception but this basic set up
should work well as a starting point.
Time to start listening

We recommend using a mouse with a roller wheel (this becomes your tuning knob!)
Press the Green “Play” button to start the receiver
Look for the Bands button and select “Broadcast” and then the 49 metre band
It should default to 6050KHz and in the main Spectrum display you should see signals
With the default settings, move the mouse to the frequency display - rolling your mouse wheel
will tune whichever digit you hover over (0.1kHz is a good one to choose)
The default settings for AM, 8kHz audio bandwidth, gain and so on should be OK…but now you
should be inspired enough to start watching the video guides and reading the manual!

Explore different antennas –for restricted space and indoor antennas
for shortwave, a “Mag Loop” antenna is recommended. (Just Google
“mag loop antennas for shortwave” to find lots of information on
these)
There are weather maps, satellite images, TV images, numerous
message systems, Air-traffic control, Plane transponder, and so much
more you can explore –lots of examples on the SDRplay YouTube
channel
