WSPR-RX exists in three hardware versions, click the appropriate link to read the documentation.
The Hardware version can be determined by looking at silver sticker at the bottom of the box.
If no sticker exist the receiver is a Version 1 type.
The receive performance for Hardware version 1 and 2 is the same but the internal construction differs somewhat . The major difference is that version 2 removes the switches, buttons and jumpers to set the receive frequency and to calibrate the reference oscillator. In version 2 hardware this information is instead read from EEPROM.
