As I was taking things apart or putting things together, I frequently found useful info on people’s blogs, things they found out by themselves, sometimes through hard work.
I came to realise that, maybe, I should start “documenting” whatever I did that could provide useful information for others. Information that I wasn’t able to find anywhere else.
That’s how I see this blog. A way of sharing information that might be of interest to anyone working on the same things as well as a reference to myself…
If there’s anything that needs clarification, more info or anything else, please get in touch (firstname@lastname.org)…

Hi Dieter, pls contact me on +32475618510: got smth very interesting. txs. johan
That is so awesome! :) I just read your 2012 post on Mares airtrim. So helpful! :) Thank you
Hi Dieter,
I just got a 8711C and are looking for schematics. Do you have it or know where to get it ?
Thanks in advance,
Marcel
Marcel, I can share you all the documentation I gathered for the 8711A (schematics, modifications, my ROM dump, calibration constants,…). About 70MB zipped. I’m not sure how much difference there is between them, it has been too long since I looked into it last time. There’s a former engineer that worked on the design that is more than willing to share information. If you need his name, I can look for it – should have it somewhere. He used to be heaviliy involved in the former Agilent newsgroup…
Hi Dieter,
Thanks for your prompt reply. It would be nice if you could share youre files. Since it is 70MB maybe WeTransfer or something similar is suitable.
In case you have the name of the Agilent engineer, this would also be nice.
Thanks in advance and best regards.
Marcel
Thanks for your
Sure, what email can I send to?

Hi Dieter, did you write a “Part 2” of the HP8640B ? Tnx, ON7MA, Jempie
Not yet unfortunately. Family life has put most projects on hold and the HP8640B hasn’t even been powered up for a couple of years..
Hoi Dieter, Ik heb gebruikte hytera’s PD365 gekregen en wil deze voorzien van frequenties. Nu lees ik op jou site heel veel maar ik ben er niet in thuis. Codeplug enzo. Is het mogelijk (tegen betaling) dat jij de juiste software op mijn laptop installeert en mij uitlegt hoe ik het moet doen?
Ik gebruik ze voor de wielersport en wil af en toe frequentie toevoegen/verwijderen i.v.m. wedstrijden in het buitenland.
Met vriendelijke wielergroet,
Marcel Kastelijn
Hey Marcel, ik zou hier zelf opnieuw eens naar moeten kijken, het is een tijdje geleden. Kan je me anders eens mailen op news1@vansteenwegen.org?
