Re: KerberosSDR dimensions and mounting

It's sure begging to be put into a small pelican case with its RPI, and some lithium battery packs. Buck charger down converters can be used to generate the needed 5v from a higher voltage such as a 6, 7.4 or 12v battery.

Re: Getting Started Guide Needed

That all makes sense now. Thanks. I can configure my cellphone hotspot to use my home network SSID. When I'm out mobile, the RPI will associate with my phone. When I'm doing stuff at home, the RPI will associate with my home network SSID, allowing me to add additional software packages onto the RPI,...

Re: KerberosSDR Interface to Gnu Radio Companion (GRC)

I have found this python code that might give a clue how the KerberosSDR streams are packed over the USB interface:

KerberosSDR Interface to Gnu Radio Companion (GRC)

Could someone tell me more about the Interface between the KereberosSDR and the Raspberry Pi that's running GNU Radio Companion? Since the RTL-SDR source block works with only one RTL-SDR, is there a block that selects one of the four RTL-SDRs, or a block that has four outputs? Are there additional ...

Re: Getting Started Guide Needed

I think the Single Board Computer (SBC) Quickstart is very confusing. It' needs a re-write. 1. Burn SD Card and insert into SBC (or flash eMMC). 2. Plug KerberosSDR into SBC, and connected the KerberosSDR's power cable. (The video shows this, but rushes through the steps) The order is important here...

Re: Raspberry Pi 4?

Does the Raspberry PI 4 image (rpi34_kerberossdr_image_301019.zip) run on RPI 3 as well?

Re: KerberosSDR Developments in 2020

I'm interested in using beamforming and/or MIMO to receive signals from four 3 or 4 element Yagis. I want more than direction finding. I would like to not only know where the main signal is, but also the interferers. The idea would be to click on the signal you want to hear and also to click on the ...

Re: KerberosSDR Developments in 2020

Is it possible to use a GPSDO with the KerberosSDR so that all four (or eight) RTL-SDR DAQs are all sync'ed to the same source?
