Using multiple SDR sticks with one antenna

Hello,

I'm trying to use multiple SDR sticks with one antenna. Right now I distributed the signal using the following adapter to two SDR sticks:

https://i.ebayimg.com/images/g/n50AAOSwvmNbBLkE/s-l500.jpg

But I noticed that increasing the gain on the first stick, makes the received voice signal of the second stick worse. I thought that it should work because I'm using the antenna only to receive and not to send signals. Could it be that the two sticks are interfering with each other? If so, what can I do to prevent that?

Entry Level And End Game SDR Gear For Ethical Hacking/Penetration Testing

Hi all,

I'm interested in learning about SDR as a hobby and a skill from what I understand its possible to do many cool and extremely powerful things with a good SDR kit, even with entry level gear you can track the real time positions of aircraft and pull live images down from satellites, as well as other borderline scary things, etc. I've nooelec and RTL kits and I've visited their websites and I believe that learning about wireless spectrum would be a very useful skill when it comes to ethical hacking and penetration testing.

From what I understand, so long as a given wireless signal is within a transceivers/antennas specification its possible to listen in on pretty much everything from ham radio to the beginning's of the WiFi bands (Entry Level Adapters + HAM Plus). I've seen videos of people intercepting RFID, Cordless Phone Calls, Pagers and even first responder radio if they are using legacy systems with no encryption; hence why I think i would be a very valuable skill.

I'm interested in getting some entry level kit but you can't do much except listen in and most entry level SDR equipment is receive only with no transmit capability. Correct me if i'm wrong but entry level set you can go from 300Hz to around the 2GHz mark? Naturally full-duplex communications are going to be needed if you are going to do pen testing, like with the wireless exploits that let you listen in on automatic door openers and other insecure devices.

I'm interested in getting USRP B200 and Ham Plus Kit as well as anything else I might need. In theory i should be able to listen listen in on anything from 300Hz - 65MHz and 70MHz - 6GHz with the B200 and Ham Plus if its compatible. What are your thoughts on this since I'm very new but i'm keen on learning.

Comment on SDRSharp Users Guide by Ignace Erauw

How to hook up a coax cable that is on one end connected to a splitter that is connected to the internet providers hub with tv, internet connectors.
That all works connecting the other end simply to a coax connector on a tuner, female.
Now, I got this little screw without pin on the dongle.
I got a sma to sma connector. I can screw this on.
Then on this connector another connector, female to another end to hook the coax on.
But I do not know if these are right connectors to use.
Can anybody explain which connectors to use. I also saw a t-uhf connector, female to sma…
What a bunch of connectors my God.
Just to hook up a coax cable. The test antenna only picks up strong stations.

Thanks.

RTL-SDR Discussion • DSDPlus not decoding

Hi All, new to this forum so be gentle with me please!!

I have successfully set up my dongle working with SDR# and all works OK. I have downloaded and installed DSDPlus following the great video by TechMinds. I'm pretty sure I have everything properly configured, but when I Tx on a DMR radio (simplex) the SDR# Spec An and Waterfall show it 100%, but it is simply not being seen by DSDPlus.

I've triple checked everything and I'm sure all of the Virtual audio settings are correct. Also pretty sure the windows sound settings are right.

Don't know where to go next really.....help please

Advice on purchasing SDR

I just starting looking into SDR's and decided I wanted to get one and I've narrowed it down the the NooElec NESDR Smartee or the Smartee XTR, from what I see the difference is the non xtr has a R820T2 with range of 25-1750MHz and the xtr has an E4000 with 55-2300MHz and the E4000 model is a few dollars more expensive. Or should I get the Smart or the Smart xtr versions that come without bias tee.

Of the 4 which one should I get? and why that recommendation.

Thank for any help and recommendations
