I dug out my old galaxy saturn turbo tonight. I wanted to see if it still works and possibly use it as my dedicated shack radio but have a bit of an issue! When i key up, my family can hear me through the surround sound in the house about 40-50ft away. I asked my neighbors if they had any interference, and they didn't hear anything. I had the internal amp turned almost all the way down when it first started. It continued even after the amp was switched off. Im using a sirio gain master antenna about 20ft off the ground and 30 ft of coax.
