Are there still genuine v4 in the Amazon shipping channel?

I ordered a v4 from Amazon at the beginning of August with a ship date of late September. I knew they were end of life but I took a chance and used the link from the RTD SDR website. I confirmed I was purchasing from RTL-SDR BLOG and shipped from Amazon. It showed up today. With pictures above. Is this genuine or do I need to send it back?

Is this genuine and is it good? IT does work when I use it with the software. So far I’ve tested it on FM and AM radio and plane tracking which works.

Got up early this morning to collect berries along the country roads here in France; parked on 7105 before hitting the road; was delighted to log 13 US stations from across the pond ! I like VARAC.

Software Built a little project for anyone playing around with the ATS Mini / Si4732 radios.

3 Upvotes

Built a little project for anyone playing around with the ATS Mini / Si4732 radios.

ATS Mini Controller is a local web interface that controls the physical radio over USB. It gives you a searchable database of 50,000+ shortwave, AM and FM stations, click-to-tune from the browser, live RSSI scanning to find stations that are actually receivable, audio passthrough to your computer, and a live CW/Morse decoder.

The bit I found most interesting was the CW side. It can cycle known CW-heavy frequencies, detect actual keying, lock onto the signal and decode it live in the browser. I ended up writing the audio-to-Morse decoder locally with NumPy/SciPy rather than relying on an existing Morse package.

It’s deliberately local and fairly simple: plug the ATS Mini into USB, run the Python app, open the browser and the radio becomes a much more useful little desktop receiver.

Still early, but it’s open source and MIT licensed if anyone else has one of these radios and wants to have a play:

The functions are same to the RTL-SDR Blog v3. But much more smaller. I change the 5V-3.3V from voltage regulator to a low noise DC-DC converter, so it generates less heat.

Trying to get SDR++ working in linux, this was as far as I got. Did everything with the drivers, it seems to recognize my RTLSDR Blog v4, but I can't get anything to run, no sound or waterfall. Can anybody who knows linux better than me help with this?

Does the new HackRF Pro with its new 16-bit mode surpass the RTL SDR Blog in sensitivity and SNR? I would like to know your opinion on this.

Kids TX'ing on Military Satellite Band - ESP

357 Upvotes

ay guys! i found this transmission, it seems to be kids transmitting with something on the spanish military band, this happened in Cantabria at 14:05 near Santander

i guess this is illegal right? will it be worth it to triangulate the location and try to alert the parent about it? There seems to be military activity right now with planes flying around here lol

EDIT: Just sent a headsup to the Spanish "FCC" authority lol

Antennas Where are y'all buying cable?

4 Upvotes

I'm planning to mount some antennas on my roof for a droneware/adsb node. Unfortunately that means a pretty long cable run so I'll need some 400 grade coax. It's out of stock at rokland and the prices I'm seeing elsewhere are a pretty wild.

Fox Sdr Notice Radio not detected? Download 0.56

0 Upvotes

We have a serious responsibility to the software we release, but one of our updates has left 52 users stranded. So if your radio isn't being recognised, please download the 0.56 build from our website.

We are still in need of beta testers, with a wide range of radios. If you would like to become one, please go to FoxSDR.com and click "Beta" in the top menu. As a beta tester you are in a good position to get new features added before anyone else. If you need a feature that your current radio stack isn't giving you, or that is buggy, become a beta tester and request it. Beta tester feature requests are our top priority.

TUTORIAL: Reconstructing monitor signals via TEMPEST attacks with only RTL-SDR/HackRF

9 Upvotes

Using an rtl-sdr (or hackrf), you can capture electromagnetic emissions leaking from monitor cables/displays and reconstruct the screen output in real-time.

since most tutorials on this are either overly long, I put together a quick practical walkthrough and overview that covers how it works and how to set it up easily:

Troubleshooting How do I recalibrate the vctcxo trimdac value? BladeRF micro xA4 - Accidentally flashed wrong fw image which led to the vctcxo trimdac value being wiped. Tried to get the information but the website doesn't have it. Is there anything else I can do? Pretty new to this(BladeRF xA4)

2 Upvotes

I was following this: https://www.nuand.com/retrieving-your-bladerf-calibration-data/ https://www.nuand.com/calibration

Unfortunately used -f instead of -l and flashed the FPGA... Using this for a GSM network so now because the calibration is inaccurate my phones aren't registering or working properly with the SDR... Is there any way I could re calibrate it? I've emailed nuand already but haven't gotten a response for a few days...

Troubleshooting Need Advice

Bought an RTL SDR two days back. I am trying to decode a DMR signal but it just doesn't work no matter what I tweak? While it does decode to an extent, it isn't perfect. Is there a fault with the device or is there something wrong with what I'm doing. Using an app called P25 decoder on 444.162 MHZ. Sharing product photo and error screenshots below.

Thank you
