If you're using the tuner in the 570, the TW-1 isn't going to do you any 
good at all because the TW-1 is after the tuner in line. All the tuner is 
going to tell you is the antenna's SWR to the radio and not what the radio 
sees on the other side of the tuner and with a higher SWR, you're going to 
get some stray RF down the coax. If that's how you're doing it I wouldn't 
worry about it if you don't hear anything in the receive and all seems 
normal.
