[time-nuts] Odetics 325 - 865

Rob
Sorry for causing confusion - I do have a 325-865, and the other number 
GPStar 330, is what is on the receiver box within, as I gather there are 
different suppliers of the Rx box ?
I must admit to becoming somewhat "punch drunk" with all this information - 
but it will unravel in the next few days - I hope.

regards
Roy
