Conclusion

 

The RXB6 is a better receiver than the other 2 receivers, although it detects the doorbell button worse.

The RXB6 is slightly better with a long ( 17 cm ?) wire antenna instead of a coil antenna.

The RX500A is slightly better than the RX470-4.

We expect that the doorbell button has a bad central frequency.

 

Transmitter WL102-341 (powered at 3V3) is very good, with the KR2202 as a receiver, everywhere in the house and surrounding the reception was perfect (tested with Learning_Mode = 9 )

Range

Notes

RXB6

15 - 20 Meters

Best tested range, comes as bundle with transmittee as 3400RF or sold seperately.

RXB8

10 - 15 Meters

Good range, similar to RXB6, little bit smaller in size

SRX882

< 5 Meters

Different findings about range and hardware. My findngs - not good! Very low range. Sold with sender STX882 which is not good either. Does not support all protocols.

Aurel AC-RX

< 5 Meters

Very low range, too expensive (appr. 8 Euro), not recommended!

xy-mk-5v

< 5 Meters

Very low range, not recommended! Sold with sender FS1000a which is ok to use.
