Nice catch, TW. Considering how low the NVIS frequencies have been as of late - with the solar minimum and all - I imagine we will hear more of these stations using the 2 MHz, 3 MHz and 4 MHz bands instead of the usual 6700-7000 kHz region....of course, as I type this, I am hearing the usual out of band amateurs chatting away on 6900 kHz LSB in Spanish..
