I think we all get quite good at watching for the noise floor between the crashes and judging how far the signal lifts the meter above that. One or two people always give an RST report followed by a "dB out of the noise" figure. Because of the very slow QSB and predictable groundwave signals these techniques prove very useful. In fact because of the small number of LF stations in ZL it is usually possible to guess a station's identity just from the signal strength! Thanks Steve and Rick for the VLF info. I turned on an ancient CR300 the other night, inspired by the mention on the reflector of old Marconi receivers, and heard VTX3 going strong. Mike ZL4OL
