Mke/greenfield 396xt background hiss
Anybody else notice this? Started about 4-5 weeks ago. Four to 5 bars solid, cystal clear and then annoying background hiss.Comms can start out clear then start hiss or can start clear then hiss.Unit still under warranty and Uniden service says send it in. Location doesn't matter, antenna doesn't matter, Control Channel doesn't matter, reloaded the radio w/RR Database, no help. I can still understand everything they are saying but it's just annoying to be in the clear and then the ssssssssss in the background. It occurs on both systems at any time, not heat/time related. Scanner on from 6am to 9pm, through headphones day and speaker at night. Just curious before it goes in to the service dept. Thanks.
