|My Ten Tec Omni V develops an oscillation a few seconds after it is turned on. This completely covers the incoming signal and shows a full deflection on the s meter. If I switch between VFO's it will sometimes stop, disconnecting the antenna will stop it, as will turning the rig off and then back on. It has even occurred while I was transmitting and the receiving station said it wiped out my signal. Many times it starts again and I go through the process once more. After 5 or more minutes the rig seems to settle down and works just fine. I took the radio to Ten Tec, but they could not find a problem with it and said it did not do it while they had it. When I got it back and hooked it up the noise started as soon as I turned the radio on. I don't know if they hooked it to an antenna or just a dummy load. It only occurs when an antenna is connected and a signal is present. Ten Tec thinks it is caused by a local signal, but my Paragon, Scout, and Yaseu 450 have never picked it up. Anyone have any ideas. It's a great radio but this problem is preventing me from enjoying it. I would love to get it back into service.
