kiwisdr thank you to alphonse romero for submitting news about the release of his new ios and ipados sdr receiver app called demod demod is a network client that connects to remote sdr servers so it can be tried out immediately with no dongle needed at all the app works as a client for rtl_tcp spyserver airspy and rtl sdr and kiwisdr all in a single app it features a metal accelerated waterfall and spectrum display am nfm wfm usb lsb cw demodulation and adjustable bandwidth gain and squelch other features include frequency memories with csv import and export airplay and lock screen controls and native layouts for both iphone and ipad it can also browse and connect to public spyservers directly from within the app which is how it can be used with no hardware of your own the developer notes that it collects no data with no ads or tracking alphose writes that demod is a solo project and is available on the us app store for us 9 99 more information and screenshots can be found on the project website and the app itself is available on the app store the developer has also provided us with 15 free codes that we will be giving away in one week to enter the giveaway simply comment on

wspr weak signal propagation reporter is an amateur radio mode designed to test propagation paths using very low power transmissions with receiving stations reporting spots in real time to the wsprnet map simone s setup consists of a raspberry pi 3b which can be made to modulate a square wave rf signal on one of its gpio pins via the wsprrypi software because a square wave generates many harmonics he used the 20m wspr shield from tapr which provides a low pass filter to remove them a dipole made from simple electrical monopole wire was connected to the shield via 50 ohm coax and the signal was transmitted at 14 0971 mhz transmitting from his rooftop in the center of bari in southern italy simone had his beacon received in england finland cyprus and the canary islands all more than 3100 km away he repeated the experiment a week later with similar results this is a reminder of how far low cost hardware can transmit with a resilient protocol like wspr simone s wsprrypi setup wspr range

std c decoder with multichannel decoding and automatic call following over on the signalseverywhere youtube channel sarah rose has released inmarscope a multichannel l band inmarsat decoder that connects directly to an rtl sdr airspy or hackrf the software can receive and decode both aeronautical aero and maritime stc c egc traffic at the same time decoders are dropped directly onto the aligned fft and waterfall by holding ctrl and left clicking and the software lets you stack aero msk 600 1200 bps high rate oqpsk 10500 bps ambe voice 8400 bps and inmarsat c bpsk decoders side by side one of the more interesting features is automatic voice call following by monitoring the 10500 baud forward link channels inmarscope can receive c channel voice assignments and automatically retune the sdr to the assigned frequency lock the carrier decode and record the ambe call and then hop back to where it was there is also a two sdr mode that dedicates a second radio to voice with a live split view spectrum so one radio stays on the p control channel while the other tunes to voice calls for assignments that never get broadcast there is also a call hunter feature that uses a squelch threshold to automatically drop the decoder when a call appears when a call is playing the built in flight map also decodes the aircraft hex icao address and looks it up on airplanes live showing the plane s position and route in real time recent updates have added a community editable band plan message search and filtering an iq recorder that also captures the seconds before you hit record and a web dashboard for browsing decoded data from a phone the software is completely open source on github and the c code can be compiled from source or a precompiled windows build is available on sarasforge dev for 15 with sarah s patreon patrons getting it free we note that inmarsat signals such as aero and std c egc can be received with our rtl sdr blog l band patch antenna

crowdfunding on crowd supply for 499 back in june and january we posted about quadrf and scalerf previously known as open space and their mission to unlock affordable open source earth moon earth eme bounce communications for the amateur radio public their core product quadrf is a 4 element coherent antenna tile with built in sdr and processing on a raspberry pi 5 apart from being able to be chained together to make a massive coherent beam steering antenna capable of working with eme a single tile can also be used for c band 4 9 6 0 ghz direction finding and spatial signal visualization quadrf can also transmit enabling point to point communication and the creation of mesh networks recently their product was launched on the crowdsupply crowdfunding platform and it has already far exceeded their 100 000 funding goal the quadrf kit is priced at 499 and includes the required raspberry pi 5 a tripod a 32gb microsd card and a power supply the quadrf mobile expansion pack costs 149 and lets you take the quadrf on the go they are also selling a quadrf six pack for 594 although as this is designed for research it does not include the enclosure antennas pi 5 or phased array

openstint an open source lap timing system for radio controlled rc car racing that uses an rtl sdr or hackrf one as its receiver in rc racing each car carries a small active near field transponder that transmits a unique identifier on 5 mhz using bpsk modulation a wire loop embedded in the track acts as the receiving antenna picking up each transponder s signal only within a short distance which allows the exact crossing point to be detected openstint digitizes this signal with the sdr and performs the decoding and pass detection entirely in software with sufficient accuracy for rc racing professional timing systems work on the same principle but rely on dedicated proprietary hardware and software with even entry level systems typically costing thousands of dollars openstint is compatible with the transponders used by the vast majority of rc racing clubs mylaps rc3 and rc4 while also supporting its own fully open source transponder design a complete decoder can be built from inexpensive off the shelf components typically consisting of an rtl sdr dongle a simple loop interface and a laptop or even a raspberry pi 3 the software has also been tested with existing timing software including lapbeeps rcgtiming and zround besides the decoder itself the project documents an open source transponder protocol includes an attiny based transponder reference implementation and describes the signal processing used for reliable pass detection documentation and source code can be found on the openstint website and over on the project s github page with the open transponder design available here atilla also sells the transponder boards on the openstint website s sales page for a reasonable 30 panel shipping 8 pcs per panel and notes that larger quantities can easily be
