Just a preview of a longer article I am working on.

Well, three months of designing and fabricating an upgrade for my Nagra V. Get ready to blow the dust off of your NV.

Here's what it looked like before: https://www.nagraaudio.com/product/nagra-v/

Here's what I did:
Swapped the HDD with a CF card and got rid of the proprietary battery. Significant weight savings (1kg) and slimmer, more flexibility to use modern batteries and modern recording medium. So far, I have tried three different brands/capacities of CF card (Transcend 4g, Sandisk 32g, Kingston 16g) and all work even at 96/24 for 30+ minutes.

Used Fusion to draw and CNC a new lid, handle, and 'backpack'.

Still waiting for Nagra to give me the password to unlock the Twin Drive option after which I will install a second CF card reader inside the unit and use its 'auto copy' function.

Finally putting it through its paces today, battery life, making new cables, and recording.

Thinking of selling kits if anyone is interested!

Would love to hear your thoughts about this project.

Yes, I am interested in finding out more about your upgrade project. Will it be user installable, cost, battery life, and maybe more questions.
