To obtain some extra sensitivity, I have now slowed down to 2 seconds per symbol, with transmissions starting 0.3 s after each full hour.

Frequency 137490 Hz,
8 characters, 8K19A,
2 second symbols (duration 21m52s)
Start times: 22:00, 23:00, etc. until 7:00 UT, plus 0.3 s transmit delay.

73, Markus
