In FrequencyCast Show 56, Carl and Pete get all three dimensional with discussion of the various types of 3D. We also get hands-on with the Triax Tri-link TV distribution kit and cover common HD questions. As a new feature, we look at a classic piece of tech - in this show, we talk about the trusty pocket calculator. Plus your questions on the Amazon Kindle, Olympus recorders and Freeview after the switchover. Links and transcripts at https://www.frequencycast.co.uk/cast56.html
