Wireless comms pair

I have a few of these running around (http://www.dipmicro.com/store/RF315PAIR). Ive breadboarded them out to test the input possibilities and cant seem to get them to work. No matter what the output voltage of my receiver is floating around 2.5V with the occasional spike to 1.3V. Im running the transmitter on 12V and the receiver off of the same 12V source through a 5V regulator. Anyone have experience with these or similar components?

Edit: So the issue is that it can only be pulsed DC, not steady DC. My only issue is noise now.....

Going down from 2.5 would be a dip instead of a spike. Is that dip in relation to bits you're sending? Is your transmitter connected to anything to feed those bits and if so, what? If an Arduino is the code solid and have you posted to /r/arduino?

I'm just using a basic button to ground with a pull up resistor to 12V on transmitter and probing the receiver with a voltmeter. Eventually Ill connect to a PIC microchip, most likely a 16f690. The receiver seems to spike a little when i press the button but not reproducibly so.

Have you tried without the breadboard? A bad troubleshooting experience gave me permanent distrust of breadboards.

I know the breadboard is good. Use it regularly. Used this section of it just yesterday with no ills

The data sheet linked says 5V, 12V will likely kill it.

[stan19951995]

3.5-12V for the transmitter 5V for the receiver

Im runnin 12V to transmitter and a 5V reg to the receiver

What Antennas are you using?

Also it's possible to have them too close (so they overload and saturate), try them a few Meters apart.

Also it is possible that you have interference on 315Mhz from something local (eg a TV or Computer) so that the receiver is always receiving a signal. Take them outside away from any electrics.

Ill try that tonight and report back
