G8AMU Multimode Receiver

My home built VHF / UHF Receiver (Click image to see full size)

This was one of my most ambitious projects back in the 1980's. Built entirely from scratch, including making the printed circuit boards and all the the metalwork!

Basically the circuit has a 28Mhz front end which is then converted by adding 70Mhz, 144Mhz, 432Mhz and 1296Mhz Converters. Modes of SSB and FM meant having two descrete I.F. strips, one for FM with a TBA120A discriminator and squelch and the other with SL1600 series chips with AGC and narrowband filter. The 28Mhz R.F. strip was mixed down using the state of the art (at the time) diode mixer.

The dial is the famous Eddystone 898 dial, what a wonderful piece of engineering, smooth and lovely to operate, cost me £8 at the time!

The SL1600 series of chips were amazing at the time, I had experimented before using the older SL600 series when I built my 160m / 80m Tranceiver. You could buy these from Birketts at any rally at three for a pound! The SL1600's where a bit more stable and easier to handle, so I bought the ones in my receiver new.

Still think that these Plessey SL chips revolutionised the analogue way of building!

I've got to say that the hardest part of building the receiver was the metalwork. It was built with just a drill, file and hacksaw and took me ages to put together while constructing the circuits at the same time.

The receiver worked well, biggest problem was the audio stage, never could get it right! The receiver is still working and sits in my loft without a power supply at the moment.

I'm really pleased with this project, made me a true Analogue Native!

Name that DJ!

How about this for memories of Radio 1! All the DJ's back in the 1960s and 70s!
Let me try to name them:
Back Row: I can see Tommy Vance and Paul Gamboginni,
Middle Row: Tony Blackburn, Annie Nightingale, Andy Peebles, Steve Wright, Noel Edmunds, Jimmy Saville.
Front Row: Paul Burnett, David Jenson, Mike Reid, Dave Lee Travis, Simon Bates , John Peel.
(but where is Alan Freeman?)
These days a lot of the DJ's on Radio 1 are from around here, Mark Radcliffe, Sarah Cox, Vernon Kay. My mate Steve Kay (brother of Vernon) works with me at school and appears on Vernon's show on Saturday morning with the Maths Problem. I have spoken with John Peel at B.I.T. back in the 70's and also DLT at Rivington Barn at a great do!
Trouble is that Radio 1 is not what it was and some of the original DJ's are now on Radio 2 and other commercial stations. John Peel, Tommy Vance and Alan Freeman are no more, but Johnny Walker and Bob Harris are still around on Radio 2 along with Steve Wright and Paul Gambougini.

This year I launched a project to produce our own school Radio Station with some professional input. Steve Kay (Vernon's brother) has taken up this project and it looks good! We already have a Radio Station (not quite Radio 1) but some thing unheard of back in the 70's!
Have a look at this:

We have come such a long way with digital technology, it is now possible for anyone to have their own on-line Radio Station and be a DJ as well!

Woolies

The end of an era! Woolworths closing forever!
So many memories, right back to when I was four years old when I got my head stuck in a revolving door in Woolworths at Blackpool. I loved 'going in town' with my Mam where we would go to Woolies to look at the toys and get some 'pick n mix' to take home. It was best when the counters were long with different stalls, make-up, cheap toys, stationary, pick n mix with the girls in the middle and you paid at each counter. I remember a girl called Carol that worked on the make-up counter. When the checkouts arrived so did the queues and Woolworths changed as we know it. My daughter Jacquie worked Saturday and Sunday at Woolies, her first job. I collected repairs from Woolworths when I worked at TAM and usually had to wait ages while they found them!
When they opened up the new 'Super Woolworths' in place of Burnden Park I was a bit confused, how could they sustain a huge store with stuff that could be bought at ASDA? Even the selection of toys was dubious. I must admit that I did get some bargains at the new store, like the first video mobile phones which they sold at a giveaway price of £45. I bought a telescope from Woolworths at less than half price and this launched me into the world of Astro-imaging.

I seem to remember that Woolworths were bought by Comet at one stage. Woolies never did get it right in the modern world ...such a pity that the store is closing ...so many memories!

Woolworths were everywhere, in Radcliffe (now Homemakers), in Farnworth and in Walkden. When I worked at Thornley's Butchers in Walkden with my Uncle Tom, when I was about 16, we were quite pally with the manager at Woolworths so when the shops shut on Saturdays Tom would sort him some meat and in return we got as much 'pick n mix' and we wanted! One of the girls I worked with at Thornley's, Gill, came from Woolworths, such a small world!

Beano

I can't finish this year without a mention of 'BEANO' my favourite comic that celebrates 70 years this year! I still buy Beano, especially when i'm on holiday.

Back in the 60's I eagerly awaited the paper boy or girl pushing it through the letter box at 7.00 on Thursday morning. Before going to school I would sit next to the fire in the kitchen and read part of the comic, but save the best till I got home from school. The best bits were always 'Bash Street Kids' and 'Q bikes.'

Q Bikes always had a soft spot for me, they had bikes with Radio Transmitters fitted and an aerial on the back. They wore a helmet with a microphone so that they could communicate with each other. Q Bikes originally had five members and later six. I even tried to form my own Q Bikes club and put a stick for an aerial on the back of my bike along with a tin for a transmitter!

How things have changed...

Now we use digital mobile phones to communicate, cyclists can use hands-free kits to talk to anyone in the world.

I can still picture the Q Bikes badge that my Uncle Bill designed one Sunday afternoon and we talked about transmitters. I think this was the beginning of something that captured my interest in analogue technology back in 1967.

Do they know its Christmas?

I love the weeks before Christmas at school!

Last week we recorded a CD of songs sung by the children. A recording studio was set up in the hall, recorded, mixed and digitally edited and enhanced.

The results are fantastic!

We grown-ups got together and sang 'Do they know its Christmas' no practice at all!

Here it is:

Snow joke!

I can't remember the last time we had heavy snow before Christmas!

On Tuesday morning the snow caused havoc, roads were gridlocked, schools closed (including mine) cars abandoned, motorways like car parks!

In this digital society we simply cannot cope with something as simple as SNOW. Even the most advanced digital technology cannot cope with it. Mobile phones used to 'text' parents to tell them that the school is shut. Weather forecasting is so accurate that it will give advance warning of snow, the MET Office has the most powerful computer in the world!

Trouble is...we rely on the technology, but not ourselves without it.

What did we do in the 1960's when snow was something that we accepted and simply adjusted to it. I can't remember my school ever shutting because of snow, people just got on with their life and got to school or work the best way they could.

Tonight on the news I saw the latest digitally controlled snow plough fitted to the front of a gritter! Fine...but will it solve the problem with snow?

Back in the 60's we would wake up and scrape the ice from the window so that we could see the snow. My Mum would put the oven on to heat up the kitchen and wrap us all up ready for the walk to school. When we stepped outside icicles hung from the gutters and window sills and we loved to pick them and suck them on the way to school. Snow drifts sometimes came to my waist and we made 'slides' in the playgrounds.

In those days Winter meant just that, these days it is rare that it snows, especially before Christmas. (Global Warming?)

We need to cope with it!

The Monkees

Back in 1967 I thought The Monkees were great!

I hated the TV programme, it was a bit silly, but just loved the music.

The first record I ever bought was 'I'm a Believer'. The later records like 'Daydream Believer', 'Pleasant Valley Sunday' and 'Alternate Title' were just lovely songs! I learned all the words and sang along with them, particularly 'Alternate Title'. Most of these songs went to number one or two in the charts and I remember Alan Freeman playing them. We didn't have a tape recorder at that time, but my mate Keith Taylor had one and we would sit in his bedroom recording the charts back in Summer '67!
I spent a whole day with Joyce who lived next door to my Uncle Bill one Sunday. She was a Monkees fanatic! We listened to all her albums and she new everything about them (A bit like Take That!) Where are you now Joyce?
I collected all the Monkees cards back in 1967, I think there were 44 of them, with black and white photos on one side from the TV series and part of a bigger colour picture on the other side. It took me a while and chewed a lot of bubble gum, but I finally collected two sets of cards. One I kept for the photos and the other I stuck together to make the big colour photo and pinned it to my bedroom wall!
Why am I bringing all this up?
After all you could be laughed at being a Monkees fan, they were the original 'Boy Band' put together by a record company to compete with The Beatles. They couldn't play (or sing) but through sheer hard work and determination they made records that are timeless! I bought The Definitive Monkees' CD not long ago and tonight I played it and still love it!
Now digitally re-mastered!
Don't knock it...some classic songs!
One song called 'This just doesn't seem to be my day' really touched a nerve, but it is not on the compilation CD!
