[Elecraft] Help with High Current issues

[alan geller via Elecraft]

Well, as soon as I sent my SOS, I realized I was telling all, I was too lazy to switch to a beefier power supply to figure that out. Our course, your suggestion solved that issue so I am getting double slow on the neuron pathways.The voltage went from 13.5 V to 9.5V on the 6th (set for 20WPM) dash and shutdown is around 9.2 V.Soo, my conclusion has to be that the SuperCaps in my trusty small/expensive power supply are getting tired.I just this minute read a review of the HPS by Phil Salas – AD5X, and he got a 2V drop at 10 WPM, so my unit seems to be out of spec and that is a "different" issue for this generally useful product.Thank you all for your quick response.......Happy 2015

 What is your K3 showing as the voltage when you change the DISP to read that instead of VFO-B frequency? Low voltage would cause the current to increase to keep the power where you set it.
