"RXB6" receiver modules seems to be noticeably better. These can tolerate interference much better, likely thanks to the cover/shield over the receiver components (and it's use of a clock crystal):
(these seem to sell in $2-3 range, so still very inexpensive)
I have this module working fine, directly powered from Vcc of Arduino Nano (clone) and "DATA" pin hooked to D2 pin on the Arduino.
This one seems to suffer from the automatic gain control of the receiver as well, if there is no transmissions for a while, gain control will "open" up all the way and when transmission is received it overloads the receiver and it takes a while for the gain control to react....
I have some Hideki (TS33C) sensors (these have been sold under various "brands" like Honeywell, Mead Instruments, etc...), and these seem to start transmitting with hardly any delay, so "RXB6" often fails to receive first few bits accurately.... but since these sensors repeat the data 3 times, it catches the subsequent two transmissions rather reliably (while first transmission it seems to receive completely only about 10-20% of the time).
Module that has ability to control the gain would be really nice... or just module with better AGC might be all that is needed (?)
