Then convert to dBm (decibels relative to one milliwatt) for future convenience: So this tells us that if we put in a -101 dBm signal it'll definitely be safe, but we won't necessarily hear it very well.Solution: Give +5v and GND to the IC’s power terminals and then give the high voltage supply VCC2 to pin number 8. Also connect the enable pins of either motors to +5v so that they are always enabled. Now give Logic 1 and Logic 0 to the input of one motors and check the output pins with a multimeter. You should get VCC2 in the multimeter if ...check, something that wouldn't be the case during the show. I once received a panic call during a changeover, with the issue being that one of the vocal mic channels sounded "gated." A quick listen at the headphone jack on the front of the receiver told me that the problem was not in the RF domain (i.e., not a frequency problem).

By Petra Paulson A "Check 100" message typically appears when a wireless receiver is disconnected or a hardwired zone is not programmed with the proper zone type. For wireless receivers... make sure the device is properly assigned to a zone on the Vista 20P control panel.For the 5881ENL, 5881ENM, and 5881ENH wireless receivers, DIP …A typical S-meter on a general coverage receiver or HF transceiver is calibrated so that a 50 µV ( microvolt) signal at the antenna input ter-minals results in a reading of S-9. This is an old, old standard which is still very useful, as we shall see. A typical modern receiver has a nominal input impedance of 50 Ω.

HI, I am trying to test out my RF 433MHz transmitter/receivers with a simple test to see if it works between two arduinos, one is a NHduino UNO and the other is a Freetronics Eleven.
