post from the past ref K3 current draw. -------------------- Fri, 22 Feb 2008 21:53:25 -0600 From: "Kenneth A. Christiansen" <[EMAIL PROTECTED]> Add Mobile Alert To: elecraft@mailman.qth.net Subject: [Elecraft] K3 NR 457 now working in Fargo ND
I got a pleasant surprise yesterday when K3 457 arrived. It was ordered June 13 and I got my Lisa Gram last week end. It has KAT3, KBPF3, KXV3, 500 hz filter, 2700 hz filter, 6000 hz filter and the FM filter on back order. I made a special test on it because I wanted to know how the KPA3 changes the current draw. I know others have asked the same question here and never did get an answer so here it is. . The current tests before I put in the KPA3. Receive 0.94 to 1.1 A TX (NO POWER) 1.56 A TX 5W 2.56 A TX 10W 3.07 A TX 12W 3.23 A The same test after the KPA3 was installed, Set up and working fine. Receive 0.94 to 1.1 A TX (NO POWER 2.16 A TX 5W 3.10 A TX 10W 3.62 A TX 12W 3.78 A All the above testes were done with a digital meter on the 10 amp scale. I would say the KPA3 adds a constant 0.6 Amp for any given power level below 12.1 Watts. I started the inventory last night about 6:00 PM and finished it tonight about 8 PM. I had a fire run, slept, went to a meeting etc. so my build time must have been about the magic 10 hours. I sure do like the receiver but have just scratched the surface of what it can do. It was worth the wait. 73 Ken W0CZ ----------------- Hope this helps. 73, Ty, W1TF, K1 #1423 waiting for a K3 __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
