OK to extract encrypted PDF?

I was pleased to see that we had the 465B Service Manual - but it has no OCR

I tried to OCR but it's protected with empty password

Is it OK for me to upload a replacement for this?

Author is maintenance script


but upload metadata and watermark in the PDF is a broken link the domain exists but wants a login. Qfissler (talk)

The manuals with the watermark were available for free download with no login or other restrictions. The scans seem to have been created with altruistic intentions, not for any sort of selfish gain. Somebody made a copy before the download links were shut down. OCRing the documents seems consistent with the intentions of the person who did the scanning, i.e., to make the information available, useful, etc. Removing the encryption so it can be OCRed seems fine to me. Peter, what do you think? Kurt (talk) 12:01, 28 May 2023 (PDT)

I regularly remove the password on PDFs for OCRing, e.g with --Peter (talk) 12:46, 29 May 2023 (PDT)

Thanks - I thought it would be OK (and in fact pre-empted your answer after reassuring myself) - I was just concerned about exposing the team to any litigation - on reflection, clearly the IP was owned by Tektronix... Still don't know why it was encrypted - maybe just a default in the software used... Thanks! Qfissler (talk)

531 Du Mont reference found

Hey, Kurt - I saw you asked for a ref for the Du Mont used in the 531 - I found a source and replied there at Talk:531

7A18N photo

Hey, Kurt - do you still have the 7A18N you took a photo of?


The manual shows the N without the "Identify" concentric to the position controls. I'd love to see the inside. (I'll add photos of mine) Qfissler (talk) 03:22, 11 August 2023 (PDT)

I think the photo was from an Ebay listing, not a plug-in that I own. Kurt (talk) 10:34, 11 August 2023 (PDT)
