# QRP_LABS_WSPR A wspr transmitter and general coverage receiver using the QRP Labs arduino shield and receiver module.\ Headless design, no display or switches. Computer controlled with WSJT-X, HRD, or stand alone transmit operation.\ A Canaduino WWVB receiver was added to provide time correction.\ A display and encoder were added, so no longer headless.\ Tap encoder - change freq step.\ Double tap encoder - toggle mode between CAT control or FRAME transmit.\ Long Press encoder - change band. Status: Works well.
