My all band and all mode QRP-transceiver is a Yaesu FT-817ND.The output power is between 0,5 W and 5 W.

On shortwave I use a Z817 automatical and batterie operated tuner from LDG.

I use wire antennas (W8010, etc.) and the famous Outbacker 1899 on shortwave.
QRP-Digimodes like PSK31 are easy operated with EZ817 (soundkardinterface fromGarant Funk) a little Netbook and the FT-817.
