Channel number sequence on VHF dials

... However what would be other side of 10? ...

3 Tacolneston 11 Mendlesham (Anglia)

No doubt this pairing also existed elsewhere ...

Rowridge/Chillerton Down (Southern) rings a bell ...

(Was 12 next to 9 for Lancashire? ..

2 was next to 9 for Lancashire, Holme Moss and Winter Hill, the other side of 2 was 10 Holme Moss and Emley Moor. 1 would be on the other side of 9 for London. So that would be 10,2,9,1. Has you stated 4 and 8 were together, don't remember any more of the sequence.

BBC1 ch12 for Lancashire came quite late, around 1964/65, lots of sets by then had seperate VHF/UHF push button tuners or a combined VHF/UHF rotary tuner with I think 6 positions just marked BBC1/BBC2/ITV1 etc, eg. Ekco/Ferranti.
Other style tuners were in use but I never saw any with 9 and 12 together.

Frank, if you reverse your order and add the sequence I mentioned, you get 1, 9, 2, 10, 3, 11 and it makes sense to add 4, 8, to this. We know from the first post that this was followed by 5, so possibly that was paired with 7 (Wenvoe/St Hilary)?

Surely someone has a set with such a sequence that could confirm the entire set?

405 channel allocation on dial from a 1967 Baird M702 CTV

The Baird has a similar layout to my KB set: in our case, 5 and 11 were helpfully adjacent for BBC (Peterborough) and Anglia (Mendlesham). A Pye incremental tuner was a PITA as you can imagine, which our second set was.

I can remember the dial on our TV in early 60's were channels 1 to 13 & to change channel you had to go from 4 (BBC) to 8 (ITV) & back here in Nottingham = 4 clicks.

It was second nature to me as a kid (in Coventry), did it without even thinking.

Manufactures in did for most regions get it right for one click VHF tuners. So for London it was 1 next to 9 and here in the North-East it was 5 and 8. For normal sequence channel tuners it was a common practice to reposition the coil biscuits so that the BBC and ITV channels were just one click apart.

Stopped with some relatives in Worksop & couldn't understand why there was snow on ch's 4 & 8 when I turned the telly on. Of course it was ch's 2 (Holme Moss) & 10 (Emley Moor) my cousins thought I was daft..

This sequencing had never occurred to me. My only dual-standard set is the Pye 11U so next time I'm in the workshop I'll take a look at the channel knob. I do know that 1-9 (BBC1-ITV for London) are next to each other.

I seem to recall in the dim and distant past on one particular set we had, my brother must have changed the position of the coil biscuits because 1 and 13 were next to each other so he made 13 for ITV London...back to 1 click.

Of course on many tuners you could move the "biscuits" (clip in coils) and put the channels adjacent if the customer wanted it that way. The numbers of course would not be correct.
Not possible on the Fireball tuner.
I think it was better to have a long spin, say in London from 1-9, as it gave the contacts a bit of a clean!.

With the tuner design that Bush used, sequential numbering was the only way - until they realised that the design was eminently suitable for the first 'Bush' button sets ...

1 to 9 was only 5 clicks if you went 13, 12, 11, 10, 9 and vice versa. As for keeping the contacts clean, they only moved to select Band I or Band III, so it didn't matter which way you went!

Ah, the "Telepic" tuner, as used on our TV75, an elegant little tuner but could never be anything else but sequential.. I remember the performance we had with ours when the fine tuning knob broke free from its shank - just at the time of the Emley Moor mast failure.. Switching back and forth every once in a while to "check up on Yorkshire Television" became something of an art, just to get the fine tuner to work 'one more time' - thank God for "Bush Buttons" on the later models!

My rented apt in Miami had a TV with a rotary VHF tuner, it was sequential 2 to 13 with a UHF bit between 2 & 13. The UHF rotary tuner was step free like the ones on the early Sony Trinitron's. (my Mum had the 1800 inches version of the Trinitron, very good picture) I suppose we were the only Country that had channel out of sequence rotary VHF tuners, unless someone knows different..

Teleton TX-12 with a sequentially numbered VHF tuner

Is the Teleton a European B/G TV? I noticed no ch's 1 or 13..

The basic Bush tuner design was little changed from the time of the first 5-channel sets, the TV22 and TV24.

These earlier sets had three tuned circuits with individual cores mounted on a cross bar so that all three moved in and out controlled by a single screwed spindle with attached knob.

The knob arrangement was different on the Band III converter, due to the need to provide Band I/III switching as well, using the same knob but, internally, the same method of ganged cores was used.

A major improvement was to place all the coils on a single former for each band, with all the cores for each band on a single rod or 'wand'. This led to the 'looks like a turret tuner' approach that you were familiar with on your TV75 which had first been used on the TV53 series, where stepped rotary cams moved the spring loaded wands in and out, the band switching being done by a separate cam, resulting in a wider gap between 1 & 13 and 5 & 6 while the switch moved.

In fact, had Bush not concentrated on mimicking the turret tuner, the TV53 could have been the first set with Bush buttons - the physical functions of both types of tuner are identical, only the mechanical interface bolted on the front is different!

Yorkshire Television? Yorkshire was still covered by Granada at the time of the Emley Moor collapse, surely?

I could have sold you a new fine tuning knob - if you'd asked ...

If you lived in the Bristol area with that tuner you'd have to go from one side to the other as Wenvoe used ch 5 & St Hilary used ch 10, unless you could get a West Country version. Did they have different versions?

From what I recall, Yorkshire TV started in the summer 1968 and the mast fell down March 69, I think the loss of revenue through a smaller service area until the new mast was constructed gave the very young Yorkshire TV a few financial headaches.
