Title : G8JNJ Reverse Engineers and Reviews the MLA-30 HF Loop
Antenna
Content : Last month we posted a collection of reviews about
the MLA-30 which is a budget magnetic loop antenna designed for
receiving HF signals. The overall consensus from the reviews was
that it worked decently for the price, but of course could never
live up to the high end loops that cost hundreds of dollars.
Title : SignalsEverywhere: Decoding HD Radio with an RTL-SDR
Content : Corrosive (KR0SIV) from the SignalsEverywhere YouTube
channel has uploaded a new video that explains and shows HD radio
being decoded with an RTL-SDR.
Title : Leif Continues his Comparisons of the Airspy HF+ Discovery,
RSP1, Perseus and more SDRs (Parts 3,4,5)
Content : Leif (sm5bsz)'s series comparing the Airspy HF+ Discovery
against various other SDRs such as the Perseus, SDRplay RSP1, Airpsy
HF+ Dual, Airspy + SpyVerter and AFEDRI SDR-Net continues again,
with parts 3, 4, and 5 now having been uploaded to YouTube. In
previous posts we covered parts 1 and 2 .
Title : Watching Lightning Strikes on the Spectrum with an RTL-SDR
Content : Over on YouTube user Tech Addict Attic has uploaded a
video demonstrating what lightning strikes look like on the radio
spectrum. To receive the pulses he uses an RTL-SDR and a simple
wire antenna located on his roof. He notes that the pulses show up
at HF frequencies, and continue all the way up to the broadcast FM
band and above.
Title : Fingerprinting Electronic Devices via their RF Emissions
with an RTL-SDR and ImageMagick
Content : Thank you to José Carlos Rueda for submitting
his simple shell script that he uses for fingerprinting
spurious RF emissions with an RTL-SDR , rtl_power, heatmap.py and
imagemagick. The result is something like Disney's EM sense created
with much simpler code.
Title : Measuring the USB Power Consumption of Various Software
Defined Radios
Content : Over on his YouTube channel icholakov has uploaded
a video comparing the USB power consumption of various software
defined radios. In his tests he uses an inline USB current meter and
compares a Perseus, RSP1, RSP1A, Airspy HF+, Airspy HF+ Discovery,
RTL V3, Nooelec RTL Mini, Hauppauge 955Q, Flightaware RTL.
Title : Electrosense: RTL-SDR Based Crowd Sourced Spectrum Monitoring
with a DC to 6 GHz Up/Downconverter
Content : Recently we came across Electrosense which is an
interesting open source project that aims to deploy radio spectrum
sensors worldwide in order to analyze and understand radio spectrum
usage. This information could be extremely valuable in order to make
more efficient use of the limited radio spectrum, and for detecting
sources of interference and illegal transmissions. The hardware
that Electrosense uses consists of just an RTL-SDR, Raspberry Pi,
antenna and an optional GPS for time synchronization.
Title : Building An Open Source SDR Based Hydrogen Line Radio
Telescope
Content : Over on Reddit we've seen a post
by u/ArtichokeHeartAttack who has been working on a hydrogen line
radio telescope , based on an RTL-SDR dongle and horn antenna designs
by the DSPIRA program , and the Open Source Radio Telescopes
website (site appears to be down, linked to the archive.org
copy). [ u/ArtichokeHeartAttack ] has documented their radio
telescope building journey , providing a comprehensive top-level
document that is able to point interested people in the right
direction towards understanding and building their own Hydrogen
line radio telescope.
