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 .As soneoene writen ina magazine SDR monitoring is as fishing with a net instead of using a hook
General advantages:
-DC to light reception with just one small SDR (SDRUno + family ,Hack RF etc)
-Active monitoring spectrum from 125 kZH to 50MHZ in once.
-Show spectrum and waterfall with ability to closeup . Signal analysis good fir finding intruders etc
-Adjust spectrum minima and maxima ranges on amplitude and waterfall speed , auto option included
-Direct recording of both audio and base band (IQ) and also with video (SDRC)
-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 noise reduction formats for de-noising 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 )
-Phasing out stations in noth AM and FM mode with separate plugin (SDRsharp) instead of using a rotatable antenna
-Bin-aural mode (or ISB decoding of AM stations) for spectrum panoramic reception that has the following advantages over the traiditional way :
Audio spatiality poss due to selective fading
Audio panning for the same reason
Fake stereo as a retired DXer call it humorously (reminds him the recordings of 80s)
Identification of hidden stations as per one video in u2b
Two station parallel listening if they are inside the filter bandwidth
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 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 (SoDiRa)
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 plug in operations)
-listen to very DX signals via remote servers that are closer to the station in mind
-real time signal strength analysis (CSV signal history )
-Direction finding via tri- or multi-angulation (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..
