I will try and see if they're back on the frequency this evening, along with the various English and Spanish language nets heard in the 6-7 MHz region. Thanks Chris!
TheRelayStation, the CBers of 40 meters are usually found in the 6600-7000 kHz range or the 6500-7000 kHz range, 5000 kHz is a new one for them (I think they're more than likely fishing fleets using out of band frequencies, the [in]famous pescadores).
