2KM Long Range RF link

Hello,

Could someone tell me what chip is used on the receiver? (i.e. not the encoder/decoder, the smaller surface mount IC)

seeedstudio.com/depot/2km-lo … th=101_103

Thanks

Hi,

The chip on the receiver is RX3400-LF.

Regards.

Thanks. Any idea what the output power of the transmitter is? I’m guessing from the output transistor and large solder patch (heatsink?), it’s more than the standard 10mW (10dBm) that these usually have?
