Hi The gotcha with carrier phase is that it is a bit more sensitive to local signals than your ear is. Yes, a lot depends on your antenna setup and as you mention, just how many watts of distribution and thousands of feet of cable you are running 10 MHz through. Bob > On May 29, 2017, at

Bob, unlike the guys who have many watts of 10MHz running around their labs via multiple distribution amplifiers, I do not have a big problem with my dinky 10MHz reference leaking into my radio antenna :-). This fall the "best band" for WWV for me during daylight eclipse would be 15MHz. 10MHz

Hi There are a *lot* of SDR boards out there today. The HackRF One is a pretty cheap one (you get what you pay for …). They go up to some very expensive setups by National Instruments / Ettus. Most of them allow for an external clock input. The usual isolation issues will still apply when
