We could move closer together, e.g. 137520 and 137519 Hz. Although the higher order sidebands may overlap, there should be no mutual interference because of orthogonal symbols, i.e. the "other" carrier going through exact multiples of 360° during the symbol integration time.

The 0000Z transmission (first one captured tonight) was best this evening ... copy below. Similar copy on 0100Z transmission, no copy on 0200Z and 1.8 dB Eb/N0 on 0300Z.
 
Marcus and Domenico ... unfortunately just noticed that the setup didn't have sufficient bandwidth to include your frequency.
