[Skimmertalk] RU9CZD skimmer QS1R died in the recent thunderstorm. Help needed.

[Prasad VU2PTT]

Igor,

I had lost the USB chip in the QS1R here from a very nearby lightning
strike some time back. Replacing it worked - nothing else was affected on
the board. Lost many other things too but the QS1R had only this part
damaged.

Good luck!

73,

Prasad VU2PTT.
