Re: My idea for a KerberosSDR #2 iteration

A few suggestions for future releases: - Replace those flimsy micro USB connectors - preferably with 2 x USB-C. If we can not find a non PD USB-C charger, it is just a matter of using a USB-A to USB-C cable. Include a couple in the package if possible -and adjust the price. Yep V2 will be all USB-C....

Re: rtlsdr.dll blog mod - how can I recognize from "standard"?

No way to know, other than try flipping the bias tee and checking for voltage.

We made the dll so it's a drop in replacement with the current interface. Otherwise you'd need another controller interface which could break over time as SDR# updates.

Re: Proper way to install drivers for rtl-sdr v3

GNU Radio probably autoinstalled the drivers from the repos'. THat causes conflicts with the drivers install manually.

Try this:

sudo apt purge librtlsdr*
sudo rm -rvf /usr/lib/librtlsdr* /usr/include/rtl-sdr* /usr/local/lib/librtlsdr* /usr/local/include/rtl-sdr*

Re: USB over-current

Must be a short circuit fault somewhere. The old high current issue with some of the silicon chips doesn't exist anymore, but it could still be a loose piece of solder or something inside the enclosure. Email us at [email protected] with the order details and your address for a replacement.

Re: KerberosSDR Developments in 2020

Can the Kerberos 4 channel board accept a clock input signal? I'm exploring the possibility of using this board in a VLBI setup since my group has access to multiple hydrogen masers. Is the only way to sync the Kerberos receiver clocks with an outside source to have a separate clock breakout board ...

Re: KerberosSDR Developments in 2020

@Harbinger Unfortunately I can't send you a private message, I'm either too stupid or it's just not possible. Sorry for spamming the forum... Is there a chance a future iteration of the Kerberos could come with a five SDR board? Something that could provide an integrated listening on the same frequ...

Re: Understanding Incident Angle

The whole incident angle convention is a bit messed up as multiple developers have used different conventions on different displays so it can be a little confusing. On the DOA graph antenna 1 will always be 0 degrees on the compass display. Let's assume that you point antenna 1 NORTH. Then 90deg is ...

Re: Direction finding with directional antennas. Is it possible?

It should work fine with directional antennas. Just use a linear array setup.

The guides assume use on a vehicle, where omni antennas are needed.

Re: My idea for a KerberosSDR #2 iteration

Thanks, we are thinking about higher end models for the future, but it is difficult once you start to go past RTL-SDRs as the basis. The challenges is that 4x HackRF's would be 4X the HackRF BOM cost. Even if that's $50 only per unit, that's $200 just for the BOM. Then add in the hw engineering cost...
