Probably not - Even the Funcube dongle down that low doesn't pick up
MSF from here in the UK, and at 66kHz I get BBC Radio 4 (198/3=66..)

However, my main SDR PC has a 192kHz soundcard. Feed that with my
LF active antenna, and MSF, DCF, amongst others come booming in.

Don't discount an active antenna plus a soundcard or ADC that will
sample 192kHz
