KerberosSDR Developments in 2020

[k5cg]

v1.6.x is awesome. Thank you for the threshold input boxes on the compass. The speed improvement is great.

In the next release could you please enable the ssh server? The only reason I need VNC Viewer is so I can get in and turn that on.

Thanks for the great product.

HI Kerberossdr

could you add seperate example that very simple correlate SDR.
Just very simple without GUI, Android or web server.
so easily understand core function correlated SDR

Would these changes require a different KerberosSDR chassis, or would they just be part of a new image that would be loaded into the SBC. Also, will support for Pi4 continue to be included in all future image releases and updates?

It will have a new enclosure and shape as the PCB is changing a lot. Right now the new version will not have built in computing, so we'll still be relying on the Pi4.

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 frequency as the DF function would be nice instead of using a separate dongle and tuning separately. Also, any possibility of GPS being incorporated into the Pi server for geo-tagging lobs so that the system could be used without a phone?

Yes this is a possibility, although with 5 units you'd probably want to use all 5 for the increased accuracy.

GPS on the server is also possible, but you would need your own USB GPS device to plug into the Pi. If you wanted to do that now, editing the code wouldn't be too difficult assuming you knew how to connect to and get data from your GPS device in Python.

[VLBI_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 take the 10MHz maser signal and solder four of its 28.8MHz outputs to the four receivers directly? Is there another way?

Can the Kerberos 4 channel board accept a clock input signal?

At least the first batch has a clock input next to channel 4, you also need to jumper the board to act as a secondary (otherwise this acts as a clock output). This functionality was/is meant for daisy-chaining two KSDR for an 8-channel setup which is still not fully supported.

@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...

I have "hacked" an ZMQ export into Kerberossdr which you can use to pass data to Gnuradio on demand. Drop me a mail at [email protected] if you want to have a look at it. Depending on what you want to do, this may or may not help you.

Would you be able to release this on github etc?
