Robin, It is normal. Current draw from this very tiny low intensity LED is not significant. This is what Fred, KE7X posted in the Yahoo KX3 group concerning the meaning of the flashes:
Here is what the KXBC3 LED blink patterns mean: Low intensity single blink every 0.5 seconds. The KX3 is shut off and the KXBC3 is in ultra low power “time keeping with alarm” mode. The KXBC3 is normally powered from internal batteries or an external power source (whichever has the higher voltage) but will continue to operate in this mode for at least 5 minutes (typically 20 minutes) if the batteries are removed. Bright single blink every 2.5 seconds. The KX3 power is on and the KXBC3 is operating normally but is not charging the batteries. Bright single blink every 0.75 seconds. A charge cycle is in progress. Bright triple blink every 2.5 seconds A charge cycle is in progress but is currently suspended due to temperature or insufficient external supply voltage. Morse ‘U” every 2.5 seconds. A future firmware upgrade may allow a charge cycle to be in progress but with a low external supply voltage. The actual charge current will be less than the normal level. Cheers and 73 all,Fred KE7X ________________________________ From: Robin <[email protected]> To: [email protected] Sent: Sunday, June 2, 2013 8:36 AM Subject: [Elecraft] Red LED in KX3... I can see a Red LED lit and blinking intermittantly inside the KX3 casing (looking through the keyer hole). It is also lit when the radio is turned off ... ? Is this normal. thanks Robin OZ6ABM -- View this message in context: http://elecraft.365791.n2.nabble.com/Red-LED-in-KX3-tp7574667.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
