Ok, looking at the frames in wireshark, looking for the timestamps that
were sent to the copy handler, it looks like only the frames from 30:80
are being used, and they're being used twice (i.e. u2b->rx_samples(0,
handlerb.get()) got the same samples that u2a->rx_samples(0,
handlera.get()) got). Is sync_to_pps() supposed to reliably return false
if the FPGA did not find a signal to sync to?
