Yesterday I've build the FROG SOUNDS 40m CW QRP transceiver.
I've ordered it as a kit from eBay Seller for about €10,- inclusive shipping to DL. The kit arrived well packed after about 15 days in my postbox.
Currently I've done 6 QSOs with the Frog and my dipole antenna.

In 2015 I've build the Frog Sounds QRP transceiver.
This little transceiver still needs improvement:

Since last weekend a new QRP transceiver joined my shack I bought her used from a German HAM via the QRPFORUM community. The transceiver is one of the older projects from the DL-QRP-AG but still a neat little transceiver. It is still offered in kit-form from QRP-Project in Berlin.
Here some analysis of my recorded spots data with my spot data collector. As of today there are 45.000 spots recorded in my database.
I've done some measurements on two RF detectors - one on an older diode detector from ELDITEST and another one on an AD8307 based one
from SV1AFN.
My WSPR data collector is now running some days and I started with some basic data analysis.
The power on the bands 60m to 20m is about 100mW!
Inspired from some work found on the Internet and the full functionality of my U3S I've build an automatic spot collector. The spot collector pulls every 5 minutes my spots from WSPRnet.org and puts it into a MYSQL database for later analysis. See the schematic for this setup
2014 CW (Morse Telegraphy) was added to the German Nationwide Inventory of Intangible Cultural Heritage.
