Good quality and works well. Don't forget to set the CS pin to gnd when you wish to receive data otherwise the receiver is sleeping. Works very well with the PJON library on github.
Item received 10 days after order. Very good packaging. Antennas are OK (tested for VSWR). Tested one TX and one RX. There are working as described.
After some tests, I have been able to make a TX-RX chain with Arduino-simulated PT2262 encoder+STX882 at TX side and SRX887+PT2272 decoder at RX side work. But only at the lowest speed. My understanding is that this is due to SRX887 module adding significant jitter on output signal. My experience with SRX887 module is not very good.
