Overview:The mainboard is version 1.2 and the RF board is version 1.0. In thisversion change, only the mainboard has been changed to 1.2, while the othersremain unchanged.1.(tr)uSDX is the successor of the uSDX Project. It´s theResult of the Collaboration between PE1NNZ and DL2MAN. The design was intendedas an easy to build (pre-assembled) Kit.2.The (tr)uSDX is a 5-Band / MulitmodeQRP Transceiver in Pocket Format (90x60x30mm – 140g). It features a highlyefficient Class E PA and Supports CW/LSB/USB and AM/FM. Right now it covers 80/60/40/30/20m and in Future there will be support for 17/15/12/10m aswell.3.It is supplied with an OLED Display, onboard Mic, (tiny) onboardspeaker and for improvised QSO onboard PTT Key can be used as emergency CWKey.4.Further on, the (tr)uSDX has a (Micro)USB CAT and Programming Interface,and while it produces typically 5W @ 13,8V Power Supply, it can create 0,5WOutput from 5V USB Supply alone.5.It is supplied with OnBoard SWR Bridge andVoltage/Current measurement Hardware, to help in tuning and operation.Thanksto DL2MAN and PE2NNZ Contribution.
