I have two S56AL MMDVM HS Hat boards that I bought from Ebay. One is a version 1 board and the other is a version 2 board. I have talked to Alexsander(S56AL) and confirmed both are china clones. Other than replacing the TCXO (which I did) he said the boards should work fine and they do.
I had no problem updating either board to the latest firmware (v1.4.14). However on the version 1 board after the update, I have to set the offset to -4000 in order to get it on frequency. Other than the odd offset, the board works fine with the new firmware. The version 2 board also works fine after updating but doesn't require any offset adjustments.
Any idea why the version 1 board would require a -4000 offset after the update?
