[Elecraft] K2 KAT100-1 question
Finished the KAT100-1 tuner and I'm seriously impressed with this unit!! Question, my K2 has installed the KPA100 amp in the K2, I noticed I have 12vdc connector at the rear of the K2, can I use this 12vdc source to power the KAT100-1 instead of running a separate lower lead to my 12v supply? The specs say the KAT100-1 pulls a max of 700 ma so it should be ok? What say U? Tnx and 73 ed __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

As always Don, thanks for the adviceI should have looked at the circuit myself..73 Eddy From: Don Wilhelm w3...@embarqmail.com To: Eddy k6...@yahoo.com Cc: elecraft@mailman.qth.net elecraft@mailman.qth.net Sent: Friday, July 19, 2013 9:49 AM Subject: Re: [Elecraft] K2 KAT100-1 question Eddy, Run the wire - that connector on the K2 is an input only. There is a series reverse voltage protection diode in the K2 that will prevent current from flowing *out* of that connector. One use for that connector is to use two power sources with the K2. A high current power supply connected to the KPA100, and a battery-backed smaller supply (like a Smartcharger connected to the battery) connected to the base K2 coaxial jack and also to the KAT100. Should AC power fail, the battery will take over and your operation can continue although at a lower power. The changeover is automatic - if power drops on the KPA100, the base K2 will still operate. 73, Don W3FPR On 7/19/2013 12:16 PM, Eddy wrote: Finished the KAT100-1 tuner and I'm seriously impressed with this unit!!
