Ok, here are 10 frequencies (last 3 digits) obtained by repeatedly invoking auto-spot with a steady S8 cw signal, around 15 wpm:
unit A - 1.78/1.58 (THR = 7) 845, 845, 845, 844, 845, 845, 845, 845, 844, 844 unit B - beta 1.94/1.73 (THR = 7) 830, 823, 829, 840, 840, 846, 831, 837, 838, 832 more variation observed with the beta version, and still often settling on the low side.
