I had updated the KiwiSDR to v1.608 prior to recording. I placed it in the mode allowing three simultaneous down-converter/receivers at maximum bandwidth. I updated my Python script to record three WWVH frequencies, alternating on odd/even hours. I added the --ncomp, -H and -L flags as recommended, and recorded in the -m iq format with the -w flag for GNSS timestamps. Eg.: Even UTC hours: 2.5 MHz, 5 MHz, 10 MHz Odd UTC hours: 5 MHz, 10 MHz, 15 MHz I omit my recordings from prior days using a longer antenna... I'm sure it was overloaded and didn't use the larger bandwidth flags. I also omit all the recordings I tried from the hotel some ~20 miles away; my random wire antenna didn't amount to much.
