Hello, I have been running the new P2 firmware and Thetis for hours now, including a couple ssb qso's. My Hermes has never run better, including the 6-bit attenuators which are now working! It may be my imagination, but it seems like the rx noise is lower!? On this AMD FX multi-core machine, Thetis CPU is around 22%, 192khz, single rx. 73 Glen K4KV
