I set up an Arduino test connection using two low gain devices. All 10 passed the text from one to the other. When I replaced the receivers with these high gain devices, they stopped working. Of the three units, one unit was initially received but stopped when returned to the receiver. The other two didn't work. In the transmitter, one of these blocks works intermittently, sometimes constantly, or not at all. The other two didn't work at all in the transmitter.
