Ok, so had some SDR issues some ‘user’ caused and other caused from not enough power (possibly) from usb-c on Mac. So I open up the aluminum case to see if the power adapter is on the board… nope.
Question, should I be looking adding the power adapter and then using usb-c and power… or just stick with the dongle? Thoughts?? Right now the dongle is not working on my Mac Book Pro, had to spool up an old windows laptop - LimeSDR-usb working on that for now.
Appreciate any suggestions / ideas
It’s interesting that you are having power problems with this. My LimeMini ran OK even on the USB2 port of my ancient MacBook Air. Is yours a Mini or the big one?
My newer machine has a USBC-USB3 dongle (Insignia brand), and I have seen no signs of power problems. Since USB-C can handle a lot of power, due to its much higher bus voltage, I would expect it to be fine. The only thing my USBC-USB3 dongle doesn’t seem to do right is power my old DVD-ROM drive, and I think this is a firmware issue. It pops up a dialog saying the derive needs to be connected to a powered port, and it most definitely is (and it was designed to run of USB2, too, so there should be plenty of power).
Ya… not sure. BUT the tests proved that my LimeSDR-USB works but when hooked up to the Mac Book, it does not work RX or TX… it was frustrating, cuz I chased that issue for several days. Oh the Mac Book is 2018, so like you said it should power no problem. I have the power usb dongle for the Lime, and plunged in both USBs, still had issues.
