One of the functions that you can enable with this unit is a Tx audio
moniter. Check out your manual. There is nothing wrong with the radio. Read
the manual.

Am experiencing RF on the chassis of the radio when transmit. Have
good ground system, clean power supply, resonant antenna w/ low SWR.
When I touch the antenna of my RF Field Strength meter to any metal on
the radio, wattmeter or power supply it pins the needle. Opened
radio, looked at ant output connectors, could find no problems or bad
solder joints. Installed 1:1 choke balun on coax at radio, no effect
on problem. Hear myself talking in the headset and when transmitting
it triggers a motion detector light mounted outside and above the ham
shack. Same effect when using a dummy load. Defect inside the radio,
anyone experienced this?

Thanks to everyone who responded. The problem of hearing myself when
transmitting is a problem in the radio as I suspected. The motion
light issue is of no concern, they are inherently prone to RF setting
them off. This one is only about 5' above the radio on the outside
wall. My main question was directed to if anyone had this type
problem with their TS-570.
