for a single station this is not important at all. All Creative
boards I have tried (all of them old ISA stuff) had a little timing
problem: the delay between 'DMA blocks' was slightly longer then
the usual intersample period inside a DMA block. This only showed
up as a -30...-40 dB spurious birdy when using sub-Hz (mHz) resolution.
So this is irelevant for EME/RA/SETI.
I also tried old Yamaha and Crystal boards, and they did not have
However, if you want to do any kind of interferometry, synchronous
sampling clocks are absoutely necesary.
