This is a very nice performing ATS3 KD1JV QRP transceiver with 4 band modules. There are many sites that have information about this radio but this one http://kd1jv.qrpradio.com/ATS3B/ats3b.HTM is by the designer of the radio.It comes with all 4 band modules 80,40,30 and 20M. It seems to work fine on all the bands. I mounted it on a simple piece of sheet metal but you can put it in an Altoids tin if you desire. There is a site if you google the ATS3 that shows you how. Included is a CD with the manual and the software for the radio included. This radio is well built and you will not be disappointed with it. All digital controls and 4 pole crystal filter too. I know of no other full featured transceiver that is this small. Read the Reviews...http://www.eham.net/reviews/detail/4758.3.1" x 2.2" board fits into standard Altoids tin.
