C SDR advantages over standard receivers:

 

This is a short abstract of all features used by PC-SDRs as far as i can collect by time .

 

General advantages:

-DC to light reception with just one small SDR (SDRUno + family ,Hack RF etc)
-active spectrum from 125 kZH to 50MHZ
-show spectrum and waterfall with ability to closeup . Signal analysis godo fir finding intruders etc
-adjust  spectrum minima and maxima ranges on amplitude and waterfall speed , auto option included
-filtering  individually the sidebands according to the received content via the mouse even for FM.
-much better and sharper audio than the typical Dx receivers (6 khz is a minimal standard  that is close to HiFi quality )
-Automatic frequency locks with SAM and D/SSB
-infinite memories . memory banks and  ability to import eibi aoki databases
-scan the  band or memories (SDRuno) and record only the transmitted content by removing the squelched  data (SDRconsole v3.14)
-Multiple digital signal nose reduction formats for denoising on all stages pus adjustable NB 
-diversity reception with ability to use ISB and/or antenna phasing for nulling out unwanted local noise or QRMer  (RSPDuo and 2 )

 

 

Digital decoders

-DSD /RDS /TETRA /TRUNK decoders
-DRM listening (by piping to external software  or by using SoDiRa)
-DAB+ listening (with external programs or )
-BY using TMate hardware feel the feel of a typical traditional receiver

Some more general uses  (not all legal!)
-Receiving GPS signals and decoding them.
-Scanning for cordless phones and baby monitors.
-Remote Telemetry Radio Receiver
-Inmarsat decoding
-Radio astronomy
-Monitoring meteor scatter.
-Decoding aircraft ACARS short messages.
-Receiving wireless temperature sensors and wireless power meter sensors
-Receiving trunking operators  

Technician pro usage :

-antenna testing (spectran-alysis )
-easier antenna installation even for sat antennas.

 

More serious or pro HF usages :

-simultaneous usage with multi VRXs (virtual receives )  form 2 up to 24? Good for info gathering esp for digital modes.
-multiple  audio recording
-stream  recording and IQ analysis for uncommon and occasional signals inside the operating band
-program these recordings (audio / IF/ full band  stream)?
-extract signal levels for further analysis and statistics using CSV method for schedules, propagation , signal analysis and other related reasons. (Uno- Console)
-Extract sonograms ( q3D view of spectrum vs time and amplitude) as photos and do statistical  results of them (Console )
-collect amateur CW content via CW skimmer for further reading (Cnsole )
-Analyze signals and measure them (SoDiRa)
-DCF 77 (77.8kHz) and RF  sensor analysis

 

Pro level  work:

-analyze digital signals with the help of external programs
-mix that with up to 24 instances for the highest level of information

 Networking:

-DX clustering -network of computers, each running a software package dedicated to gathering, and disseminating, information on amateur radio DX (long-distance contact) activities.
-remote listening  with other SDRs.  (SDR Console and networked programs )

And : (Kiwi SDR operations)

-listen to  very DX signals via remote servers that are closer to the station
-real time signal strength analysis  (CSV signal history )
-Direction finding via triangulation  (TDoA)
-SSTV  decoding
-Wefax decoding
-Decode RTTY  and NAVTEX signals the easy way.
-Interconnect for propagation analysis via IBP and WSPR
-Loran
-IQ signal analysis ....

and many more because as time passes Kiwi's are continuously updated.

 And more important: sending  immediately [reception] reports !(with audio and /or technical analysis as extracted from the program used )

More to come..
