Re: No Device Found

i've got my KSDR USB-C port plugged into the "Quick Charge" port (the special 1 of 4) of a RAVPower 12V car charger and have had no problems

Re: Some questions about KerberosSDR

But does it really matter what kind of reception antennas have when using identical antennas (assuming the reception is identical across all 4 antennas for any given frequency)? are you certain that is a safe assumption to make? and are you certain higher gain (typically) as wavelength decreases cr...

Re: KerberosSDR as a simple RTL-SDR replacement tuner? Seriously.

You enjoy your rosey view of them, I will post and flog them relentless, and deservedly so. you, sir, have drawn a conclusion without evidence. obtaining a license and capability to encode/decode using DVSI technology is presently a simple matter of commerce. simple consumer commerce, as a matter o...

Re: Some questions about KerberosSDR

[*]Can this SDR be used for wideband scans with single antennas or do antennas need to be changed per frequency/band? KerberosSDR is 4x RTL-SDRs with some circuitry to make it coherent. So even if you're not using the coherent features, you can still use it as 4 independent tuners. So you could use...

Re: Setting the KerberosSDR EEPROM

suggest adding "-m RTL-SDR -p KerberosSDR" to each of the commands in the second set.

in this way, you can tell the RXs in the KSDR box apart from any other RTL-SDRs starting with a basic 'lsusb'.

Re: Interfacing KSDR in C/C++

but allow yourself a full review of the existing code first before declaring yourself too lazy to be lazy :geek:

Re: Interfacing KSDR in C/C++

grab a copy of the KSDR code and see how it's done

Re: KerberosSDR as a simple RTL-SDR replacement tuner? Seriously.

about DVSI -- you buy an AMBE-3000 chip and you have your license. really, it's not a big deal. no need to lodge irrational complaints. feed it baseband data and it returns audio samples. then use AMBEserver so you can process data-to-audio streams on your LAN (source code is readily available). i h...

Re: KSDR device is not working!

mag mount whips are meant to be used on a metal surface which offers a 1/2 lambda path length from the location of the whip. 'ground' is capacitively coupled at the mag mount.

Re: Feasibility of a Passive Weather Radar

the WSR specs are so you can see not only the frequency but the emitter power used to illuminate the weather stuff. your chances of -passive- weather radar are low, unless you just happen to live near a WSR installation. :-)
