I've received a couple of letters to my house saying that they've been scammed off some 600 dollar amplifier. I am the original KI7JCW. I don't use my callsign, or my license for anything. I got the license for a grade in my communications class and am not really into the field. If you are the few people who have been scammed, I'm sorry but it was not me. You should try to cancel your transaction. Sorry for the inconvenience.
