Wideband pulsing noise & Noise Blanker absence: I'm in trouble! [NB added in v1.152]
1 / 12 kHz = 83 usec. And the NB needs a couple of gate samples to work properly. So going below 100 usec doesn't get you any improvement.Moving the NB to a higher sampling rate in the FPGA is one option. But that will take some effort. Or increasing the audio bandwidth, which has its own problems.

Direction Finding and linking existing KiwiSDRs
Wow -- check Christoph's latest post: https://github.com/jks-prv/Beagle_SDR_GPS/issues/130#issuecomment-347206064It's a plot of a ground wave TDoA solution for DCF77 using three Kiwis relatively close by.

Sound recording from multiple opened browse windows for diversity reception?
When you include the --kiwi-wav flag the GPS timestamps will also be added to the files when recording in IQ mode. This will allow post-processing the data for the very interesting projects now ongoing: Christoph's HFDF work and zfyoung's diversity reception.There is code in the repository (proc.m, read_kiwi_iq_wav.cc) for Octave (Matlab) to read the files and create various plots. I haven't tried this myself but see the Github GPS timestamp issue (https://github.com/jks-prv/Beagle_SDR_GPS/issues/130#issuecomment-346085747) for examples. -

Make sure your fork is updated. Things are changing quickly. I just took out those extra prints that had been left in.
