It would have to be a very specific kind of device. The "Wow!" signal isn't broad-spectrum noise. It's one specific frequency, and it just happens to be a frequency near one we expect to be used as a signal.
Somebody could well have been walking across a field with a 1450 MHz generator. I don't know why; maybe it was a prototype of a portable microwave-oven/Walkman mashup. If so, it was leaky, and perhaps that's why it never caught on.
