V3 dongle from Amazon

Post by P-40 Warhawk » Tue Feb 26, 2019 2:42 pm

Hi Everybody .
I bought a V3 dongle from Amazon , not a RTL-SDR offering . That was a mistake , Don't buy unless it's from RTL+SDR . The person that was sell it had put a jumper in it and the tuner sensitivity was low .
Now to what my question is , The person that was selling the dongle had mod it And I was wondering if anyone might know what he was trying to do ?????????? I am attaching two pictures , sorry the quality is poor , I always had problems with digital cameras . The third picture is a copy offline so it's a good picture and I am showing the jumper in red .
P.S. I sent it back to Amazon for a refund

Sorry, but your two last pics are super blurry, and it's difficult to actually understand what's going on there; do you have other pictures, or is it all what you have since you shipped the item back to Amazon?

Nice user by the way, cool to see fellow warbirds :P

We have a small batch where we've reduced noise on the HF bands, and one of the changes is that jumper. All subsequent batches have the jumper embedded onto the PCB..

But where did you buy that one from? The jumper on that one looks strange

Hello,
I am a noob and this is my first experience with rtl-sdr. I bought it from Amazon too. Your store lists it as RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with Dipole Antenna Kit. I have downloaded a couple of free programs to use with it. SDR# and SDR Radio.com is the software I installed but neither of them recognize the dongle. I am clueless to why it will not recognize the dongle because I followed the links from your site to the software download site and installed the software packages from there. So, If you could provide any assistance I would appreciate it. I really wish your site had a driver to install and then it might be able to be recognized from there. At no time that I plugged the dongle in did say anything about installing a driver.
Thank You,
Micah J. Kimbrough

Hello,
It would seem that I fixed it. First of all, installing various software changed were it played my sound at so I changed that. I watched a Youtube video and he selected list all and then picked one of the items from the list. I picked USB reciever (interface 0) and that worked. I was able to listen to a local FM music channel though I had to change it to wfm from nfm.
Thank You,
Micah J. Kimbrough

Hi, Concerning the initial post in this thread, I have a V3, batch 2 dongle (purchased about January 2017 from Amazon) and am wondering if my dongle has this mod (wire jumper or etched trace). If not, would it make a significant improvement to the S/N ratio if I added the jumper, and what would the increased S/N ratio be? Thanks in advance!
