Glad you raised that point, Brian. In my Sunday school classes I ask the question: "what does the fuse protect?" It's a revelation to all when I give the right answer. On our 240V distribution system, a melted cable can lead to a severe shock hazard and I'm guessing that in the 110V centre-

Hi Ron, Thanks for the analysis. You pointed out several things I was unaware of related to these types of fuses. Nice to learn something new! I'm in the process of redoing the power distribution in my shack, so will take this info into account. Fortunately, it's been a while since I've blown an

Hi Julius: I measure just over 20 Amps under some bands and conditions running the K3 at 100 watts. Like the K2, I suspect the current draw varies a bit depending upon the rig, the actual parameters of some of the transistors, etc. That's normal, according to the K3 specs, which rate the current d

Ron, I've been using my K2 cable with my K3, including contests, without an issue. Considering what the KPA100 will do with my 160M setup, in the way of drawing current, I think there is enough wiggle room not to worry too much. The K3 barely gets warm when I run :o) 73, Julius Julius Faze

Me too, but I realized that the K3 draws somewhat more current than the K2/100. Depending upon the band antenna, etc., the total current can exceed the rating of the rating of the 20-amp fuse in the K2/100 power cord. Ron AC7AC -Original Message- > ...whether the K2/100 power cable is i

...whether the K2/100 power cable is interchangeable with the K3/100 (i.e. do the Andersons have the same orientation on K2 and K3)? Yes, they have the same orientation. I initially ran my K3 with my K2/100 cable. 73, Lyle KK7P ___ Elecraft mail

I haven't been able to locate this information in the documentation, so perhaps a kind soul could oblige? In anticipation of a K3/100 kit's arrival, I would like to know the length of power cord supplied and also whether the K2/100 power cable is interchangeable with the K3/100 (i.e. do the And
