There was not an LED supplied with the HFSignals v3 uBiTx.? I assume that you have one of the enclosures supplied by third parties.? In order to provide correct information, it would be best to know the enclosure that you have, as well as the function of the LED (TX/RX, Red/Green, or just ON) as well as what you want it to show.
