6730.5 kHz 6.7305 MHz 6.730.5 MHz Spanish language Spanish speaking SS speakers
6730.5 USB Spanish

Another nice catch, Traveling Wave.

It seems like the 67xx and 68xx kHz range frequencies are home to several interesting radiotelephone link systems, including the RRTS (Rural Radio Telephone Service) and similar point to point fixed services....6790 kHz USB has been logged before, as well as other frequencies discussed in this post.  I have monitored several multiple-station QSOs on frequencies similar to 6730.5 kHz.  Several of these loggings all have two things in common.  The use of the 6700 kHz to 6800 kHz frequency range, the use of USB mode, and the use of offset frequencies (frequencies ending in xxxx.5 kHz).  6771.5 kHz, 6772.5 kHz, 6888.5 kHz, etc.  All in USB mode.

Hopefully FFM can chime in as to the use of 6730.5 kHz.  Thanks for the log!
