Hi to everyone on the list,

I wonder if anyone on this list has any back issues of the UK magazine
"Wireless World"?

I am trying to get hold of a complete copy of an article which
appeared in the February 1965 edition. I will be more than happy to
cover all expenses of copying etc.

The item of interest is an article about a wobbulator designed by Ken
Johnson which uses "Turns Cancellation" in order to tune the inductor
within the oscillator.

After reading an incomplete description of the design in "Amateur
radio techniques" I have been successful in getting the design to work
but I understand the WW article had much more detail and background
information which I should like to see.

Many thanks,

Des.

A quick look on my shelves shows that mine only go back to November 1966.

You might find them available at a *good* library (or they might get a
copy for you), Wireless World was the sort of 'professional' magazine
that libraries used to subscribe to.

A "wobbulator" is basically a Voltage controlled oscillator often used
to "sweep" through a range of frequencies repeatedly. A typical use is
to sweep through the I.F. frequencies of a radio receiver while
adjusting the I.F. tuned circuits. By displaying the IF output on an
oscilloscope whoose horizontal sweep is synchronized to the swept
oscillator you obtain an image which represents the response of the
tuned circuits. While "tweaking" the tuned circuits you can see the
results of the tweaks in real-time.

I hope this helps.

Best wishes,

Des.

Hi and many thanks for the tip but I just attempted to post to
sci.electronics and got the following message...

"You cannot post messages because this group is only available as an

The most recent post seems to be from 2005

He said "sci.electronics.*", i.e. one (or more) of the groups with names
starting with sci.electronics. Pick a suitable one.

He definitely needs to get out more.

Yeah - the old Samuel & Hutton used a motor to drive a rotating tuning

I have a fair few articles clipped and/or scanned from WW going back
to that period. Amusing how, as fast as they changed their name to get
rid of the 'old-fashioned' term 'wireless' ... that's it's come back
into fashion!

Anyway .. I don't have a copy of that article ... but if you go you
any library, and fill out the details on an 'Inter-library loan
request form', they will get you a photocopy of the article. It will
take a few weeks, and cost you a couple of quid or so, but you will
get it.

If you know anyone at a decent university then they are pretty likely
to have stocks of WW going back that far. I have photocopies from the
late 1950's of some of the early days of solid-state audio design
which went on in the pages of WW, grabbed from when I worked at UCL
briefly.

You feed it with an audio signal and it modulates an RF frequency with it
- like a low power FM transmitter. It is often used for aligning the IF
stages of radios. Squirt it in at one side of an IF transformer and watch
the other side with a scope. You see a lovely response curve that you can
adjust in real time by tuning the core(s).

Doesn't sound like you have ever been out of the ward yourself at all..

not, alas, February.

Hi again,

Many thanks for looking through your back issues of Wireless World.
Thanks also for the tip on 'Inter-library loan request forms", thats
handy to know.

As luck would have it someone had a copy of the article in question
and has e-mailed me a copy but thanks again for trying.

Best wishes,

Des.

Thanks for the info' Andy,

I will keep the url for future reference. As luck would have it
someone found a copy of the article and has e-mailed it to me but
thanks for taking the time to respond.

Hi again to everyone in the group,

Just a few lines to say "thanks" to all who responded to my request
for a copy of the wireless world article.

Someone has kindly e-mailed me a copy of the article so I can now
continue my research.

Thanks again to everyone who responded.

Best wishes,

Des.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "The Medway Handyman"
saying something like:
