- Using an RTL blog SDR dongle, an Android smartphone and an OTG cable to hear HF, VHF and UHF signals. This is a great option if you want something simple to receive AM, FM, SSB and CW signals over a wide frequency range.

Can’t beat a bit of radio and white snake on a Sunday morning uk
There is also SDR Angel and SDR++ and a heap of other others for things like aircraft ADSB, ships etc...
It seems like there is something for every interest, and more available every day.
I use GQRX running on Debian for the laptop.
Yes, I learned the lesson of buying the cheap RTL-SDR clone. It never worked for me. Using your link from a previous video, I obtained the genuine one, and it works very well with the laptop. Now I need to try my android phone out. Thank you for another great video.
I"d rather use a SDRPlay RSP type receiver connected to a desktop. While the idea of on a phone is cool its a bit small & easily could hit the concrete floor if you tripped on the coax that feeds the antenna.
If the RTL was integral to the phone, that might pursuade me.....
Be aware, not battery friendly powering via USB OTG.
Look for a powered OTG cable. Available on the internet.
The first OTG cable I bought years ago from Harvey Norman was around $10 I think. After much use I needed a new one as a wire must have come away, as it only worked when I bent it into a particular position. About two years ago I bought 2 on eBay for $3.80. Australian stock. I see they still sell them, but the price has doubled now. One thing to be aware of is not all Android phones support OTG. Of the three phones I've had, none supported OTG. My two Android tablets do. There are small apps available that will tell you if it's supported. If you have a cable, then by just connecting a USB storage drive, it should show up if it's going to work.
They sell a tiny 1:9 unun that matches a random piece of wire well enough for many frequencies. For newbies who may not want to build an antenna coupler it's quick and easy.
The other RTL dongles drove me nuts trying to get the software to work, it appears to be more software related than the dongle.
Would I be right in thinking I could set something like this up with my iPad
I'm guessing it would work but don't have an ipad so can't say for sure.
Another very important difference in the recommended dongle is that it uses a SMA connector instead of the GPS style (sorry, blank on the name) used by the clones.
It's much more reliable than the GPS connector.
Thanks for the reminder to buy the V4 SDR , do you know of a OTG cable with an extra input for external battery pack to keep the phone charged?
73! Have a great day!
Yup, it's called a "powered OTG cable". Check the usual internet sites.
Hey there!
I saw this kind china make dongles.
Thanks for your video.
Have a nice day!
