The Hemel transmitter is much lower power than the one at Crystal Palace and I believe is only intended for people which live in a low lying area which can not get a decent signal from Crystal Palace transmitter. Are you certain of the Hemel frequency? http://www.ofcom.org.uk/static/reception_advice/dtt_pocket_guide_2-8.pdf lists digital mux channels as below and none match 816MHz: Hemel Hempstead 48+ 55 60+ 59- 62 65 How about trying the 48+ channel which should be at 690166666 Hz. The others can be calculated as: (channel * 8MHz) + 306MHz Then: if "+" add 167kHz, if "-" subtract 167kHz. Have you checked to see which mux channels your freeview box is using? Are you using the same aerial for the freeview and Freecom? Jon
