Bob and Graham,

 

Thank you for the OPDS information. Rob will check for Bob?s signal. University of Florida archives its raw VLF data. If you need raw or processed data for a particular event I can ask Rob to send it; I?ll send a list of receiver locations.

 

73,  Jim AA5BW

The transmitted OPDS signal is the same as for just plain OPERA.  However, it has to be very stable and phase coherent. 
Yes, am on 29.499 for the night using OP2H  mode-Bob
