In 2015 I've build the Frog Sounds QRP transceiver.
This little transceiver still needs improvement:
- The output is still only 400mW
- The key-click is horrible - even with the additional audio cw-filter.
- The suppresion of harmonics is very bad. Check below.
If someone has any ideas how to fix this, please Diese E-Mail-Adresse ist vor Spambots geschützt! Zur Anzeige muss JavaScript eingeschaltet sein!.
