frequency problem with pavel wspr redpitaya

Post by pa0slt » Thu Jan 23, 2020 12:08 pm

Hi folks,
I did a stuped thing... i put 20 volt to the input connector of the redpitaya running with wspr of
pavel.

The wspr receiving runs at low frequencies normal, but above 10 MHz the sigs are weaker
then an other redpitaya...... at 10 MHz it is 10 db,, at 14 MHz it is 25 db , at 21 MHz is is 48 db.

So,, is the redpitaya died???

Or did i do some other stupid thing in the receiving system?
