In the category of total ham vanity, I've acquired a nifty LED "On Air" sign with my call to remind me (the dogs, cats and wife) how important I am when I transmit! What's best practice to hook up to my fabulous Flex 6500? TX1, 2 or 3? Do I need another relay. Its 12VDC. Probably really annoying for CW, huh? Blink-blink-blink-blink.
