Radio problems

OK, I'm lost on the radios again. I couldn't get a program to work correctly so I ran the program that I used in May, and it doesn't work either. I have checked the wiring, I have checked the program, I have tried using different BS2 boards. I ran the transmit program, and had a radio that wasn't connected to anything so i could hear the signals, but there aren't any signals being transmitted. The transmitter goes into transmit mode and the orange light that show that it is transmitting comes on, but the receiver doesn't pick up anything but static, no bleeps and blips that area supposed to be there. I made a list of troubleshooting ideas in May and have gone through that, and I have tried different radios, and I have researched what a modem is supposed to do with signals so I have a pretty good understanding of what it should do. Nothing is working, does anyone remember anything I did before that made it work?
