For FrequencyCast Show 78, we visit leading sci-fi convention London Film and Comic Con 2012. We also get a new wireless heating system installed, discuss at Pinterest, look at upcoming changes to Freeview, meet the 2o12L station team and get interviewed on Phoenix FM. Plus your comments on the 3DS XL from the HMS Belfast, as well as news on Hotmail and TalkTalk TV. Links and transcripts at https://www.frequencycast.co.uk/cast78.html
