Recording IQ data with >20kHz bandwidth from a single KiwiSDR
It looks like I found a way to combine several IQ data streams from the same KiwiSDR recorded at different (by multiples of 12kHz or 20.25kHz) frequencies, so that the combined spectrum is continuous, see here. This uses GNURadio, so for everyone not familiar with GNURadio there is a learning curve.
There are obvious applications, i.e., monitoring of HF radars such as CODAR, and WBHF waveforms.

External GPS Clock frequency suggestion?
This is great work!
I remember that besides the MSK signals you have mentioned also DHO on 23.4 kHz is/was not locked to a frequency standard. -
