It is the selling off of frequencies that is my main concern, after Ofcom realised the commercial trading value of the radio spectrum. Millions of pounds can change hands for swathes of frequencies.
As the frequencies can be turned in to revenue streams the cost of having 3 or 4 MHz of exclusive bandwidth must be astronomical. Band III went from TV to Private mobile radio, now to DAB.
Band I where BHTV seem to be going for to me is an unknown, there was Low Band PMR which was once the remit of many of the local authorities and utilities such as Water, Electricity etc going back years ago was in the 70 to 87 MHz area, and was generally phased out with licences gradually moving up the frequency band.
Do not get me wrong I would be very pleased to see 405 TV on air again, but it will only be as an oddity for many, and viewers would be the likes of us interested and dwindling collectors. Perhaps if it is done as a low power system just around London to start the system off.
What I could envisage on the back of BHTV is a internet streaming service of programs going to be displayed on Computer screens or to perhaps a 'Hedghog III' able to take the stream and push it out through the modulator to a 405 TV. With suitable compression such as H265 I would think the IP bandwidth would be reasonable compared even to the music streams we have today.
I like working with valves, I like making things with valves, but from some of my peers I get why, things advance just accept it move on, perhaps not all want to see the nostalgia of a bygone period.
