    Bing free keyword tool. The Concertmate 990, also released as the Casio CTK-601, sounds very crystal clear compared to my other keyboards as well as to much more expensive keyboards I have used over the years. And for a price this low, $250, it is an unbeatable deal.

    • May 09, 2012  0 Answers I bought an MFJ-9420 20 meter radio reciever and there seems to be an issue with the volume. Radio works, i've heard people on 20 meters with a tuned dipole, the only thing is when i turn up the volume to hear better the S meter maxes out and I lose audio to a pulsating buzzing/humming noise that sounds like speaker overload.
