However, the OI says "Low Battery" while using the bootleg 9V adaptor that we found lying around.
Also, we tried setting the receiver and the transmitter up within a few feet of one another, and yet they still didn't work.
What is a dongle? That sounds funny. In any case, I doubt we have one.

I think your problem may be two fold.
First- the adapter must be 9 volts. Anything higher and you risk damage to the OI. It also should put out 1500mA (1.5 amps). You can check this fairly easily. On the wart it's self, it should have a label. On this label, look for what ever comes after 'Output:'. It should read something like '9VDC 1500mA. If it is less then this rating, then the OI will work, but the radio will probably not have enough juice to really transmit at the level needed.
Secondly. You mentioned that the low battery light is on. If this light is one when you are teatherd, then your RC is probably not getting enough power either. That light comes on when the RC's voltmeter drops to a certain level. This value can be changed int he program, but I think it defaults to 10 volts. Usally this doesn't cause radio problems, but I have noticed it can crop up when using a very old battery or if there is a bad connection between the RC and the battery. How is the RC being powered? Did you end up powering through the cars 12volt system? Did you ever check the quality of that power? It may not be adequate. If this is the case, then your RC radio may not be fully powered, which could result in the same symptom. Check the voltage at the RC's power terminals with a voltmeter. It should read right around 12v, give or take 2.
