If the voltage drops from 13 to 12.4 with only a 3 amp draw on a 30 ampere Astron, you likely have a severe power problem somewhere.
Measure the voltage on the Astron output terminals when you key the K2. If the drop is present at the Astron, then you have a severe Astron problem. If not then you most likely have a severe problem with power cord, power connector, etc. Gone bad, not fully inserted, whatever. Always rule out mechanical stuff before tearing apart the radio or shipping it back to Big E. Wires and connectors are mechanical things that wear out. Do not ever trust wires and connectors. Expect them to go bad. They will. I have seen a male "F" connector for RG-6 stuff that did NOT have the threads grooved. Owner came within half a phone call and three cuss words of sending a RX switch box back to manufacturer accusing them of using non-standard female F connector jacks on the box's back plane. Never, ever trust wires and connectors. They are necessary, but they are also your covert enemy. They have atomic level situational detectors and know when you are in a contest, or taking your only shot at a new country you have been chasing for a quarter century, or otherwise emotionally vulnerable, and thus gleefully fail at times of maximum impact. My low power K2 drops the 30 amp Astron from 14.4 to 14.3 when I key it at 10 watts. I have changed the internal settings to obtain 14.4 volts out. Better supply voltage for just about every "12 volt" gizmo in the shack. But that's totally different subject. 73, and good luck, Guy K2AV On Mon, Sep 5, 2016 at 2:38 PM, sniels...@nc.rr.com <sniels...@nc.rr.com> wrote: > I have a K2 that just returned from a full going over, config, and realign. > > I am getting the HiCur warning real quick when I key it up. 40 through 15 > meters will produce the message when the power setting is adjusted to 6.7 > or higher.
