I have put together a simple white LED bar on the bottom of the KX3. No holes, it clips over the bottom thumbs screws. Runs off of 9 to 16 VDC @ 25 mA, regulated by a LM7808. I have a schematic and pictures for those interested. BTW the bar is a plastic DIP IC stick with a AL sheetmetal plate to make the attachment. Simple tools. Mel, K6KBE
