All, Interesting pathsim test: Contestia 16/500 and Olivia 4/500 move along at about the same wpm rate, but there's quite a bit of difference in performance.

The simulation was identical for both modes -- mid-latitude / disturbed. Olivia 4/500 did print error-free at -5db SNR so there's a difference of 5db between the two. Whether or not that actually shows on-air is another story. Tony -K2MO
