The numeric display on my Omni V has started to change intensity. For a while it's bright, then dim, then bright. This doesn't effect performance, but needs to be rectified. There doesn't seem to be anything that the rig is doing - transmitting, tuning, bandswitching, etc. - that causes the change. I have cleaned the contacts as best I could with DeOxit. Any ideas? 73 de K8HJ John
