Could some genius please help me with a design to create an RX sensor for 868.35 Mhz.
Sparkfun & others have sensors for 433Mhz etc but I cannot find one for 868.35 Mhz.
So I either need to develop a similar sensor from scratch or can I buy a 433 Mhz sensor, unsolder the 433 Mhz receiver and replace it with a 868.35 Mhz receiver.
I have a number of salvaged items that transmit at 868.35 and want to capture their data.
I am not sure if it is ASK or FSK either.
Really appreciate any help.
Thanks and kind regards,
