What was the First British FM Receiver?
Having two Bush VHF41s to repair, which date from late 1954/early 1955 prompted the above thought. Given that FM in the UK didn't start until 1955, the '41 must be one of the earliest FM radios. Does anyone know of an earlier one?
On a related topic, when did 10.7Mc/.s become the standard FM I.F.? According to the Trader Service Sheet 1203, the FM I.F. of the VHF 41 is 19.5Mc/s |

Re: What was the First British FM Receiver?
How about the Cossor 523 ?
According to Trader sheet 1200, this was released in September '54, two months before the Bush set. The Cossors' I.F. is the standard 10.7MHz as well. Regards, Andy

Re: What was the First British FM Receiver?
How about the Philips 543A, (Radio! Radio! fig 763, p 194), Another 1954 set claimed to be one of the first AM/FM receivers. I have got one of those somewhere .

Re: What was the First British FM Receiver?
Well, the first domestic receiver was, in fact a television. There had been much talk about the possibility of FM broadcasts in the late 40's, and English Electric's first few tellies had FM radio coverage in readiness. Thats 1950/51.
Wonder if any of the sets lasted long enough for their FM to be actually used. TTFN, Jon |

Re: What was the First British FM Receiver?
I remember FM test transmissions being broadcast on 405 TV channels on Sunday mornings in the 50's but can't be specific on the actual years

Re: What was the First British FM Receiver?
Well, in the case of the English Electric sets, they were FM and, I believe covered the full range of 88-108MHz (yes, teh full 108MHz).

Re: What was the First British FM Receiver?
I believe that EMI produced an FM tuner in 1951.
Murphy introduced the A242 in 1954. It employed a strange valve line-up. A Mullard EC92 and a Mazda 6L34 triodes are used in the FM tuner. The other valves are Mazda. 6C9, 6F15, 6LD3/EBC41 and a 6P1 as the output valve. The HT rectifier is an UU9/EZ40 Regarding the English Electric TV with FM radio. I have a model 1550 in my collection. Might worthwhile trying it out on FM sometime. DFWB. |

Re: What was the First British FM Receiver?
Thanks for the interesting replies. I don't remember the FM tests on the TV channel in the early 50s(I was only 8 in 1951 and we didn't have a TV then). I think the first regular FM was broadcast from Wrotham (or Alex. Palace?) in 1955. What I do remember is FM Stereo tests in the mid 60s, using Third Programme FM as one channel and TV sound as the other

Re: What was the First British FM Receiver?
Would that be 1967, when the BBC decided upon the Zenith G-E Stereophonic Broadcast system?

Re: What was the First British FM Receiver?
Russel W. B. you are quite correct, and I assume the TV sound channel used was BBC2, since that was FM, whereas at that time BBC1(405lines)sound was AM
