My rig is an Elecraft K1 with 5 watts of power. It's an excellent rig for the CW QRP entousiasts.
It has all the controls and functions a CW operator needs and is very compact in size and very light.
I'm operating usally around 14060 KHz which is the international QRP frequency. I have made also a lot of contacts at other regions of the band with very good results.

My first rig was a RockMite 20. This little kit with 0,5 watt of ouput is excellent for beginers to ham radio and also to kit building. I mainly used it to hear CW and learn. It helped a lot to hear actual CW on the air operating.
