Re: Update rate not showing

Ahhh here's something - I get a " library error -5" right after I hit enter for the 4th rtl_test And each tuner runs fine individually right? If so, that seems to confirm that it's a power issue. The final tuner activating causes them all to crash because the power draw becomes too high for your su...

Re: Clock oscillator on KerberosSDR?

It's possible, but as 28.8 MHz is required it would require additional circuitry which would add cost...

Re: Update rate not showing

So I always have the kerberos connected to my pi before boot up but if I have all 4 switches on before boot up the whole pi freezes. If I leave them off(while connected), wait for the pi to boot, then turn all of them on everything is fine in terms of system freezes - however, even in this procedur...

Re: Single radio failure on my KSDR?

Hey please contact us at [email protected] and [email protected] for a return + replacement if one unit has failed and nothing works to get it back.

Could it be a faulty DIP switch? If you wiggle the #1 DIP switch around, does the light flicker?

Re: Bias-T on KerberosSDR?

There is an ESD diode on the input, so best to decouple voltage from the input, otherwise the ESD diode could activate.

Re: SDR x8 and order issue

We have left the potential ability to combine units to get up to 8 RX, but we have not yet been able to test this as the software is not capable of scaling this way yet. At the moment the IGG platform only allows one order at a time for some reason. Eventually we'll move off IGG, but at the moment t...

Re: Strangest thing with my antenna!

Yes that could be happening. The inner conductor should actually be shielded, so if you can somehow connect the outer shield of the coax cable to your SDR if might work even better as that is more exposed to the RF. Really you want a proper antenna like a Discone or dipole up in your attic though. T...

Re: Update rate not showing

Well I'm positive I'm getting enough power. Here's another thing. It's recommended to connect the kerberos with the pi before booting up the pi but if I do so, I cannot turn all 4 antennas on because the CPU usage jumps up to 80%+ and the whole system freezes Ah well if you're not connecting the Ke...

Re: Bias-T on KerberosSDR?

There is no bias tee on the current version of KerberosSDR. We tried to include it on the design, but unfortunately it coupled in a lot of board noise, so the circuit would need to be redesigned to prevent this problem.
