The miniPIG was designed by Dieter (DIZ) Gentzow, W8DIZ.
Operating with a VXO it tunes about 10kHz of the 10m band (28.055-28.065).
So far I've connected with about 35 different DX countries using the miniPIG.
This is a rig has an excellent receiver, rivaling my Elecraft K2 for sensitivity, and is very quiet.
Power out is about 1.5w.
Diz, W8DIZ, has a website for the minipig: miniPIG Information
Diz also designed a multiPIG, using band modules for multiband use: multiPIG Information
