Yesterday, I ran my QDX for the first time off a 9V / 160 mA power adapter. You know, one of those things similar for charging your phone.
It was receiving properly, and I was even able to make some QSO's.
Today, I decided to use the same kind of power adapter, but this time a 9V / 1A version.
The QDX started out normally by flashing the led rapidly, then the led went off and smoke came from the QDX.
What in Earth may have happened here ?
I did not raise the voltage. The only thing that was new was that the adapter can supply more amps.
Any help would be appreciated.
Tnx,
73 Hans
