Hello all, I had problems reading the circuit for the airzone 1052a from Radio Museum. Monochrome TV was able to post a very legible copy of same. I have the same problem with the circuit for the Airzone model 6852V. Wondering if someone could e-mail me a legible copy of the 6852 v circuit. I believe it is in AORSM NO 5. Page 28.

The AORSM 1052A schematic at Radiomuseum was ripped off from Ray Pedri's AORSM disc. These are typically low resolution TIFF files which are degraded even more when converted to PNG files to suit Radiomuseum's requirements.

Hundreds of Ray's AORSM's schematics have been uploaded to Radiomuseum without authority.

The Airzone 6852V schematic at Radiomuseum was uploaded by Stuart Irwin and is legitimate.

That aside, I will send a good legible copy of the 6852V to Brad tomorrow for inclusion to this thread.

That is also a Peal & the AORSM disk circuit, is just as tatty. Airzone also, like a few others, used chassis numbers which appeared in different cabinets. Can it be married to one of those?

€Hundreds of Ray's AORSM's schematics have been uploaded to Radiomuseum without authority.“

Yet they have the audacity to put their watermark on them. And put limits on how many you can download without joining.

Airzone 6852V is in both Volume 5 & 6 of the AORSM and are both barely legible, Volume 6 being the worse.

The Peal version is just a copy and paste of the Airzone page and is just as bad.

Here is a copy I just scanned and it may be just only slightly better than the Radiomuseum version.

Copyright law around the world can be confusing and because it is different in each country, is difficult to enforce.

In Australia, copyright expires 75 years after the death of the author or in the case of a corporate entity, 75 years after that entity ceases to exist. In the case of Crown Copyright, it is 50 years after the material is published. This puts the AORSM books on the free market as far as I have been told by several people.

There is some confusion about what happens next. Ray Pedri has indeed made a CD containing the AORSM circuit diagrams. However unless Ray has purchased the copyright from the original publisher, there is a big grey area as to whether he can claim copyright over the CD. The recording is Ray's work but the material isn't, unless substantially modified. This is not a legal opinion, just my interpretation of the law and it is either right or wrong.

That said, when a member of this site has uploaded material from Ray's CD, I have removed it on Ray's request as a mark of respect and also to maintain compliance with this site's Copyright Policy, in particular the section titled "member contributions".

Any material provided to RadioMuseum that contravenes any copyright would require the owner of the material to discuss the matter with the administrator of that site. However, as I said before, if they refuse to co-operate, enforcing one's rights could wind up being very costly. The site is hosted in Germany by the looks.

I cannot imagine Radiomuseum having the resources to verify the copyright status of every submission, so they rely on the contributor to comply to any rules in place.
I see a difference in submitting a circuit scanned from an edition of AORSM that I have and one taken from the CD, as the latter does not recognise the work put in to make the CD.
In the same way, I see the restrictions put on by Radiomuseum as a means of recognising the work they put in to the site.
Declaring my interest, I purchased a CD many years ago, but a couple of computer changes have lost the means of now reading the CD. I also paid Radiomuseum a one-off joining fee, some $10 or 20, years ago. I have recovered that payment many times over in knowledge gained and enjoyment of my radio experience.

You are right, Harold. Resources for checking the origins of any file are usually limited to giant corporations with huge legal budgets and legal teams to go with it. I am in the same boat here. I need to rely on people doing what is right and following that, dealing with complaints. The other thing I don't want to do is be an adjudicator and usually prefer to let the parties to a difference of opinion try and work things out in one way or another.

I guess it may be wasy to argue that Radiomuseum runs ads and is behind a paywall for certain services, so they should be able to handle it but at the same time their membership is much larger and therefore more resource-intensive to deal with. It's a swings and roundabouts situation.

Harold, you can buy for very little money an external CD / DVD / Writer drive that plugs into a USB socket.

I recently discovered a pdf that I created for a Vintage Radio thread here had been uploaded to Radiomuseum. I requested that it be taken down and the response was “we’ll look into it”. Two months later and it is still there.

Kevin Chant has lost his entire J.R. Publications Japanese transistor radio schematic collection to both Radiomueseum and Elektrotanya.

I’ve been told that Radiomuseum aims to have the most comprehensive schematic collection available in the world. A good guess would suggest that a large proportion of these schematics have been ripped off from other sites by its members. So yes it is a bit rich for Radiomuseum to watermark them.

Radiomuseum joining fees can be waived if you promise to actively submit images and schematics. Members can contribute just one schematic page and in return download 360 pages for free or accumulate credit points. Like a 1 to 360 give/take ratio. Very generous of Radiomuseum!!

I think we can now see what the problem is!

Maybe Brad will have to add a watermark to any future photos, if that's easily possible.

I never liked Radiomuseum's antics, and since they require your address I would never sign up.

Actually and mainly through thefts from the rural mail boxes, I have a PO Box.

Require an address? Residential address?

If that is the case I would not be signing up either. Webmasters should only be collecting what they need to legally run their sites. Nothing more, nothing less. This is why some sites get hacked - the hacker wants that sort of information to sell off or hold the site owner to ransom.

I recently discovered a pdf that I created for a Vintage Radio thread here had been uploaded to Radiomuseum. I requested that it be taken down and the response was “we’ll look into it”. Two months later and it is still there.

If I ever obtain evidence of a member or guest of this site lifting the property of others for the benefit of any other website that person will run into some serious problems. It's something that has had to be dealt with before unfortunately and it will not be tolerated.

What can be done about things like this?

Well sometimes not a lot but there are options when substantial proof is obtained:-

Banning the member from this site permanently.
Public shaming on a fairly widespread scale - let's face it, in this game, the regulars all know each other or know of each other - a thief can expect no less than being sent to coventry by the whole vintage radio fraternity.
Australian Federal Police.
Letters from solicitors.

Just give them a false address. It's not like they are going to check. I don't even give my real address for online purchases that are for Click and Collect. If I'm collecting it they don't need to know my address! In fact, I don't even give them my surname, just the first letter of my surname. You have the email confirmation when you collect the item to prove it's yours. I've never had a problem.

Ditto. With the almost daily news of systems being hacked and personal details being spread around the Net, I remain anonymous except where it is unavoidable.
