Is there any way that I can use one of the programs that turn the PC sound card into a signal generator to inject some amount of noise into the radio at various points for testing? I'm not confident in my very rudimentary antenna, and while I understand that the sound card can't output at a receivable freq, perhaps it can cause some noise that I can hear on the phones... ?
