I notice retail stores do not want to sell computer microphones anymore.
I noticed that, too. None at Best Buy, none at Fry's...
Had to get one at a swap meet.
Anybody know why?
Most PCs sold these days are laptops, which usually have microphones built in.
Gamers buy high-dollar headsets, not stand-alone mics. Often times they have USB sound cards built in.
Hard-core audio types pick up pro mics and HQ interfaces like the Heil USBQ.
Back when I was doing a lot with Skype I picked up a headset at one of the Office stores for a few bucks. I hang it on my external speaker when I want to practice sending code using the radio's keyer, since the radio doesn't send the tone through the data connection. Using it FLDigi can decode fairly well, even with my terrible fist.
