Most ham receivers that purport to have coverage down there really
don't. I thought my Flex 5000 should hear that handily but all it ever
heard were images of the AM-BCB. The HPSDR Hermes board in my ANAN-10
hears WWVB a treat. Direct Down Conversion (DDC) is your friend and
anyone considering playing with this stuff really needs to be thinking
about a DDC receiver.
