On Air LED Sign

  • Updated 2 years ago
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.

David,

Use TX1, TX2, or TX3.  I would use TX2 since I am using TX1 to key my amp.

No, you would not need another relay. 

If you are not using full QSK & set the CW Delay to a value long enough that the rig does not drop out of transmit between characters, you would not have it flashing when you send CW.

Ray, I am dumb as a board. Help. So I connected my nifty self-important LED "On Air" sign to TX2 -- zip line to my 12VDC power source, sign-to-power interrupted with an RCA plug to TX2. I am assuming TX2, on transmit, closes the loop and supplies 12VDC to the LED sign. When not transmitting, the power should be off. Appears TX2 is closed and the sign is on continually. 
What did I do wrong?

David,

The TX1-3 jacks do not supply power - they short to ground. Connect your 12VDC power supply to the plus terminal of your sign. Connect the - terminal of the sign to the center pin of the TX jack you are using. Now it should work.

Works like a charm. Thanks, Ray.

I think you should keep it connected during CW to check if either you, your wife, dogs, or cats are prone to Epilepsy.

:-)

But on the serious side Ray has good advice!   Now I have to go and get me one of those!

My daughter gave me one of these signs for fathers day!  It hangs outside my shack and is wired to a WIMO switch which I can control via a phone app.  When I'm operating either at home or remote I just turn on the sign via the app and my daughter and wife know I'm on the air from wherever I may be..
