yes, there are still some 8 MHz signals - "S" is silent pending a visit someday by the ops..., but hre are two in the West some could try for:
8193.75 or so - "MarinDit" 10 mW nor. Calif. - about 80 dits per minute
8149.5 (chips) Inyo Whooper dasher - daytime only second harmonic quite strong - also 4097.25 with a "whoop" in LSB mode. 70 dashes per minute or so, if I recall - 73 - v-v
