Here are some pictures of my Elecraft K1 and K2 project. I use both TRX for QRP contests as well as for traveling.  Both tranceiver are equiped with the automatic tuner.  With my allband vertical, like a triple leg matched with wireman an a 4:1 balun direct connected to the TRX, I got a lot of DX contacts in QRP. K2 is CW only and QRP.  K1 is equipet with 4-band filterboard.  Unfortunately this board is not available anymore. The power supply is an "old" Lenovo Laptop PS with 16 volts. Just put three 3A diodes in series.

In case you have any questions do not hesitate to send me an email.
