WSPR-RX exists in three hardware versions, click the appropriate link to read the documentation.

Hardware Version 1

Hardware Version 2 HF Low

Hardware Version 3

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.
