Thanks for adding this in. I'm hoping to use this for a high power rocket tracker this weekend.

Re: Direction finding for intermittent signal

Great, thanks. I'll do some more digging in there.

If you come up with anything like you're talking about, I'd love to see that too.

Thanks!

Re: Direction finding for intermittent signal

Thanks to both of you. I'll try the sample size first to see how that impacts things with my transmitter. For the code to do modify the compass calcs to not update when the signal is below a threshold, do you mind pointing me to where I could add that? I made it as far as estimate_DOA in hydra_signa...

When I use the compass webpage on the Pi or the Compass Android app, it looks like the arrow points toward the signal just after i...

Re: Raspberry Pi 3B vs 3B+

Thanks for the replies, everyone. Good to know about the 3B vs 3B+. I have heatsinks & a fan already in the 3B I was hoping to use, so I'll try that first. The link that wasn't working was this one (the actual link in the email - gives a 404): https://link.indiegogo.com/click/5c8b1e5395a7a1363b3fc0f...

Raspberry Pi 3B vs 3B+

I got the shipping notice and I'm excited for my Kerberos to show up soon. I have several Raspberry Pi 3B units, but I don't have a B+. Is the extra speed (~15%) of the 3B+ required or is the 3B fine? FWIW, the long Indiegogo tracking link for the kdsr guide in the Update #10 email didn't work for m...
