uBITx CW Conditioning Adapter

uBITx CW Conditioning Adapter PCB only – $4 ea. shipping included


Fall recharge… QRPGuys will not be shipping product from now and until most of October. We will only be providing e-mail support, and answering inquiries. If there is an issue with a kit already shipped, we will address that upon our return in October. We appreciate your patience for a needed break.


Thanks to Jim Sheldon, W0EB, we have this circuit that eliminates the issue of the erratic keying when using a straight key attached to the uBITx, and improve the use of a mechanical paddle with the internal keyer. It is the pcb only. You supply the simple components for only the portions of the device you wish to use, straight key input, paddle inputs, or both, and mount internally in your uBITx chassis using #2 hardware. It uses FET switching to eliminate any issues related to mechanical contacts interacting with the inputs to the uBITx. The board is small, ~.58″ W x 1.62″ L. See the manual below for the complete BOM.
