<font face="Comic Sans MS">Thanks for clearing that up for me. I'm
guessing you're a ham. I've never encountered anyone not a ham
who uses terms as narrowband fm or wideband fm, psk and so on.
The only problem I could think of would be the computer generating
interference with whatever you're trying to receive.<br>
