@Vinny Yep, that's what I figured. Thanks for the info!

Microhard pDDL Carrier USB Dongle + Microhard pMDDL2450 2.4GHz MIMO Digital Data Link
Accidental overvoltage damage (7.4V).

I'm still able to access the WebUI and apply settings.
The RX LED is solid green.
No radio activity (as expected)

My question is: Which component do you believe is damaged, the carrier board or the modem? Or both?
Do you think that either is salvageable?

Thanks!
Chad
