Just going to Wade in in total ignorance here - was the UHF band ever used for television broadcast in the UK? In America tellys would switch between vhf and UHF

625 lines (and digital terrestrial) have always only been on UHF in UK. 405 lines was only on VHF.

Keep an eye on eBay. The GEC was £36.00 and only needed a minimum of work. There has been a BT306 with built in VHF radio since that went for £26. There have been some other nice restored 405 sets all going for affordable prices. Buyer collection only which can be a bit of a logistical nightmare. The Aurora is the expensive bit but once you have bought it you are there. The "minimum of work", if it required me doing anything remotely electrical, would no doubt result in an explosion that would flatten the entire building given I haven't done anything of that ilk for 20 years... And even so, buyer collection wouldn't work for me, given that I don't have either a car or a driving licence...

Many old VHF transmitters were kept going long after they were officially defunct because there were concerns about little old ladies stuck in cottages halfway up hills and mountains who would not be able to pick up UHF.

Indeed. In 1938 they picked it up in the States as well: www.youtube.com/watch?v=4SniB0JEDGs

You might find one just down the road from you ready to go!

Interestingly enough I am getting best results on Band 1 C4, the picture is somewhat washed out on C1 and the Band 3 channels suggesting digital "interference" from fixed mobile and DAB. C2, 3 and 4 give much the best results with the Aurora here, Mid Wales so it would suggest C2, 3 and 4 are still free around here, or on the other hand it could be component drift on the wafer components in the turret tuner, it is 54 years old after all!

When the Aurora is connected up to my rather complicated TV distribution cabling in the house this weekend, interestingly I may be able to record programming in 405 lines to DVD as I am pretty sure my Sony HD / DVD Recorder has a VHF tuner. Will give it a go and let you know how the results work out as and when. I know that early VHS recorders could do this quite well, I am not sure how well the DVD will do, time will tell.

Attachment DeletedAttachment DeletedUnfortunately I was unable to test the recording potential in 405 line of my Sony DVD Recorder as the Aurora plumbs in after it and the Sky box. However it does appear to have a VHF tuner so the potential exists to play later. These are the World Athletics Championships from earlier on today

Finally it's back up & running following moving house twice last year! Ran the Co-ax, connected the aurora & fired it up. Can't wait to watch The Web of Fear as it should be viewed again!
