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!
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.
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.....
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 found that a lower resistor across the crystal earphone worked better. I was using a 1N5711 diode and not a crystal when I did it. I found that 2K was best in my setup.
