Very good idea ! 🙂

As Costas said, it is just A1D modulation, so perfectly compatible with the existing keying hardware for CW. Opera is used by Amateurs at 475Khz and 136KHz were it outperforms other weak signal modes
and can be mixed with the standar CW transmissions. Opera just transmits a callsign. Depending on symbol period it can take from 32 seconds to 32 minutes. Due to the strong signal of SAQ it would be
possible to use Opera 8 minutes which can be decoded with very low S/N using correlation detections. Probably good enought for trans Atlantic decodes in daylight

Worth a try 🙂
