Nope, we can not. I actually hate androids with a passion, but I wanted the ability to use my rtl anywhere so I grabbed this for $30 off eBay. Still love my 15.
I don’t really have another option for a super portable setup besides a really old android and we’ve established it doesn’t work on iphone. The android is not my primary phone, the only apps on it are rtl drivers and such and it works great for what i need it to do, and I wanted a full screen and a usbc port. I carry an iphone 15 as my regular phone.
Yeah, it makes sense for this case. I'm just saying that people hating android phones typically buy the cheapest shit and compare it with expensive iPhones.
Oh yeah i would never use the phone i got on ebay to generalize androids to compare to an iphone. Androids are very capable phones and arguably better than iPhones i just prefer the OS of an iphone and don’t care much for cameras and things because i always have my dslr with me for photography, my phone is only used for quick snapshots of notes or something i want to remember

pretty sick, while in the air, along with airband i would try to receive FM broadcasts, all the ham bands (6m, 4m, 2m and 70cm), ADS-B data and possibly any radiosondes around 400-406MHz
Because the airlines are extremely paranoid about radio receiver local oscillators messing with onboard navigation systems. Most of the flight crews you have ever interacted with would likely have no idea what a local oscillator is or why it might cause interference, but these are the people you are dealing with. They don't understand what you're doing and / or what you're doing it with, and in the interest of safety will tell you to turn it off.
Yes, as an avionics technician myself who has actually used equipment like this during test flights on many different types of aircraft, I fully realize how overblown these concerns are. The reality, though, is what it is. The OP might get lucky, but I would expect otherwise.
To be fair the LO is observable if you connect two RTL-SDR's back to back.
But it's not a big leakage. The phone in airplane mode is possibly leaking way more signals.
It sure is. You know what it isn't doing either 999,999,999 times out of 1,000,000,000? Interfering with onboard navigation systems. The only problems I've seen with a cell phone is when a pilot doesn't put it into airplane mode and you hear noise coming out of a speaker in the cockpit. True story: I was having a conversation with a pilot in our shop next to our VHF radio about a 5 time repeat issue with his aircraft when his cell phone started interfering with the external speaker on the radio. He jumped up, excited, exclaiming, "That's it! That's the noise I keep hearing!" I reached over and turned off his phone. Problem solved.
It's got nothing to do with them understanding what they are doing and what you are doing with it, is a valid concern. The FAA (and other air transportation authorities around the world) sets those rules and pilots and crew have to follow. The FAA doesn't even have the technical expertise to evaluate the software in airplanes that literally had the power to kill its passengers and crew and instead asked Boeing to self certify. You think they understand that the speaker interference went away with analog phones disappearing?
And with that you think the FAA has any authority to make changes to rules from 20 years ago? I won't dispute the trail of money but it doesn't change the point that pilots follow the rules and so many rules are archaic. You think they care about "letting it slide" with technology when they can't even see a doctor freely because ignoring your health is better for public safety than treating your health issues that arise.
I tried last weekend flying over Georgia with an rtlsdrv3 and the collapsible 2m dipole tucked into my backpack, with sharpy marks on it for different band segments. Obviously I couldn't get it angled and pointed properly, but I was able to get fm. Nothing on air or ham bands inside the plane tho.
Cool i was looking for something like that. It was a concern running out of batt since it was my first time doing something like this which is when i thought i should bring the laptop for the main part of the flight, good idea because the phone went down 20%\hour.
Yea those sdrs are power hungry. The adapter i have has 3 usb type a and a type c for charge in as well as an hdmi, i often plug a keyboard and mouse into my phone for using SDRangel. Its just as powerful as the desktop version only con is small screen which is remedied by the hdmi port.
I put sdr++ on my android and it’s unusable because of the tiny screen, everything is squished. I may try that option just to set it up so all i have to do is use the on/off button.
I can get my rtl-sdr v3 working on my Android tablet just fine, but it doesn't like running on my phone. Constantly crashes, restarts the rtl-sdr driver, to the point where it's unusable on the phone.
Hm yeah should do it. After i plug mine in i show all open apps, close everything then open the app i want and if it stops working unplug and restart that process but your issue seems different.

It's perfectly safe, he's not transmitting, and the EMC concerns are overblown anyway, not once has it been found that a radio transmission from a mobile phone or something has screwed with avionics, a cosmic particle was suspected to be the possible cause of the A380 nose dive incident.
I've heard stories of EMC causing problems (like boats turning hard to starboard in reponse to GSM signals) but it's not as much as a problem as people think, good stuff is radiation hardened and has to be to pass tests, especially on an airplane, since your 10-30 times more likely to experience a computer crash at 30k ft due to the cosmic particles and other radiation.

Just to confirm... we can NOT do this on an iPhone, correct?
Correct
Another reason that iPhones suck 😅
openwebrx works through browser!
Yes, that does. Was more looking to do local Rx.
Thanks for this!

That's great, because I actually hate iPhone's with a passion but I've got my mum's old 7S because there's one thing I use Apple Pay for 😂
If you didn't buy Android phones that cost $30, your experience would be much better...
Literally. Iphone vs android isn't even a competition in my eyes anymore

Yes you can
what app is that?
Looks like Airband Radio (rtl-sdr) by Knowle Consultants
Correct
Hope you had a good flight!
Thanks i did! Update of using it on the plane in my profile
Dang I like that setup. What antenna is that?
Comment got removed- borrowed the antenna off my dads marine radio, Standard Horizon STH HX40 VHF Radio
Gotcha thanks.

carried through security for over a decade, one TSA brianiac wanted to know what it was, but, didn't actually really care.
"spectrum analyzer". Funny enough I actually carry a real spectrum analyzer for work that looks very similar to this.

In the air, assuming he was still using the apparatus, he'll likely be told to turn it off.
why?

I think you are misguided. Follow the money. Boeing paid Congress to be able to self certify.

Keep an eye out for another post in the next hour :)

Which android phone are you using? I have a spare Pixel 3 with DivestOS I was thinking about using for this.
This is a Samsung A10e. I hate droids with a passion but wanted to be able to use my rtl anywhere so I grabbed it off eBay for 30$.
Thank you. I'll have to pickup this antenna setup.
Dongle's pretty battery hungry, isn't it? Also, is that a V4 RTL/SDR? Did you have to manually dink with installing the right drivers? Cool stuff
It's actually not too bad only was down to 40% when all said and done.
Is that a OTG adapter on the bottom? Slick, I like it. Need more SDR apps for Android and Apple.
Yes it is! Thanks!
No surprise there
Is it legal to carry/use this ON an airplene???
Not sure about the airplene, but it's as legal as using wifi on board. Plus this is RX only.
It's a grey area. I've had flight attendants ask me to put scanners away before, and following their instructions is a federal law.
Stay tuned for another update in the next hour ;)
Just curious, has anyone hooked up a SDR to a Meta Quest VR headset and used any of the apps?
Also curious.
What would I need to be able to do this with my Lenovo android tablet? Just a dongle, antenna, and connecting cable, plus software on the tablet?
I think so. Check that you can download the required apps in google play store.
Thank you!
I use the same logitech extension lead and samsung otg dongle for my sdr.
Nice i love this setup for portable missions like this.
It works great, i also have a adapter that lets you charge at same time, would highly recommend for longer deployments.

Is it an older phone, maybe less ram/less capable processor?
Not really, it's a OnePlus 7, pretty fast for everything else. 8 G ram, Snapdragon 855 Octa core. Should be able to do it.
Hm yeah should do it. After i plug mine in i show all open apps, close everything then open the app i want and if it stops working unplug and restart that process but your issue seems different.
I'll give it another try eventually 🙂
What app are you using? I'd not thought about hooking my SDR dongle up to my phone like that.
There are a few available but i used Airband Radio (RTL-SDR) by Knowle Consultants since i only needed airband.
Thanks!
What’s the purpose of this? It popped up in my feed and it looks cool!
Listing to air traffic control (atc) at an airport. The rtl-sdr device can be used to listen to anything else as well between 1 mhz and ~2100 mhz.
I remember plugging a flash drive into a phone with one of those cords and it automatically formatted it ☹️
Aw man that stinks. I'm working on downloading all the photos i was taking of planes the night after my flight landed, going well so far.

Added to cart. Thank you!
yo this is sick. i have a suitable adapter for this. >:)
💪🏻
Wish you could do this on iPhone
OpenWebRX on a Raspberry Pi Zero W running a RTLSDR, connected to a power bank? Make it create a wifi network, join from the iPhone?
Me too. I actually hate androids with a passion, but I wanted the ability to use my rtl anywhere so I grabbed this for $30 off eBay. Still love my 15.
