All, Had an opportunity to do some weak signal testing with KH6TY. Signals were in the noise both ways and stayed consistent throughout the test. It was the perfect opportunity to test for sensitivity; ionospheric distortion aside.
We tested Olivia 16/500, MFSK16, DomnioEX4 and DominoEX8 FEC. Although it is a bit slow wpm-wise, the Olivia mode seemed do very well. It would have been more of an apples-to-apples test to compare Olivia 4/500 to MFSK16 since they would have been somewhat closer in terms of wpm rate. There's always next time. See below...
