Still off after space walk. Nothing heard on 437.55, 437.525 (a frequency they accidentally set it to once), or 145.825. ariss.net shows last activity at 2017-03-30- 0430 UTC. Looks like there was a space walk today which they have to turn the ham radios off for. https://blogs.nasa.gov/spacestation/2017/03/30/spacewalkers-successfully-connect-adapter-for-commercial-crew-vehicles/
