I love my Framework laptop. While there's much to like about them, the fact it uses expansion cards is something I really appreciate. I'm also a software defined radio enthusiast. I hate having a clunky SDR hanging off my laptop.
Why can't anyone make an SDR dongle built into a expansion card?
Oh, that's why. There's no market for one. But that didn't stop me.
I don't own a 3D printer, nor do I have access to one. I also have no way to build PCBAs. So where's what I did.
- Small Phillips head screwdriver
My intent was to cut the male USB A connector down to the bare minimum allowing everything to fit inside the expansion card housing. I practiced on an old thumb drive and all I did was destroy the connector. So I settled on letting the PCBA stick out slightly.
I gutted the expansion card, attached the USB adapter, placed the SDR inside the housing, glued it down, and voila.
