Talk:Hartley oscillator

From Wikipedia, the free encyclopedia

This is listed on cleanup for expansion, and I can't see why. It looks excellent to me other than some minor grammar issues.

There are certainly things that could be added, mainly historical things like who was Hartley, some of the many valve circuits that used this oscillator design, and more recent applications. But I can't help wondering, if someone knows of more material that belongs here, why they just don't add it themselves? I'll try to dig out some history myself. Andrewa 00:29, 16 Mar 2004 (UTC)

I added part of the circuit of the Scott 310E receiver, and a tiny little bit about its usage. TuringBirds 22:06, 7 Sep 2006

I Listed this, as it looked like the single sentences for structures and advantages/disadvantages could probably be expanded, and explained, rather than that there are particular grammatical or other errors in the text. I don't know of more material that belongs here, but it seemed likely, when I looked at it, that there was some, but I don't know enough about the subject to add anything, so added it to cleanup, so if there was anything useful to add, someone who knows about the subject can add it.

I think that's just a matter of the style in which it's written. I could easily rewrite it in essay fashion, but for this material IMO the existing style is fine. Andrewa 01:48, 17 Mar 2004 (UTC)

I'll defer to you on this, as you seem to know more about the subject than me. Silverfish 12:49, 17 Mar 2004 (UTC)

The article starts by saying that the Hartley oscillator is a "... type of inductively coupled oscillator ...". This is not true. Granted the design is usually implemented using a tapped inductor, but there is no requirement to do so. The oscillator design is just as valid if there is no mutual coupling beween the two parts of the inductor. The circuit works by deriving the feed back from the tapping point, something that is will still work with no mutual coupling. This is analagous to the Colpitts oscillator where there is no mutual coupling between the capacitors.

[edit] Scott 310E oscillator schematic

I think the tube based Scott 310E oscillator should be replaced with a more modern BJT or FET version. The audience for these articles probably knows very little about tubes (myself included) and the schematic is more confusing than helpful. -Roger 20:00, 31 October 2007 (UTC)

[edit] Missing item

Presumably the oscillator requires either a valve or a transistor but there is no mention of this in the article. Biscuittin (talk) 23:09, 1 March 2008 (UTC)
