Looking for a K2 power supply that is small and lightweight to use in hotel rooms. I tried the unit from Morse Express and it was just a standard notebook type supply that put over a S9 noise level into the K2. I use a MP1 antenna and it is usually within 10 ft of the power supply and rig. If I use this type of supply with my outdoor antennas at the home QTH, the amount of noise induced into the radio is minimal, but with the antenna in the room, it drowns out the signal on 40m completely and 20m is pretty bad as well. I did try moving around the counterpoise, taking a ground wire from the K2 to the electrical ground on the center screw of the wall plate, none of this helped lower the noise picked up by the antenna and rig from the power supply. I do have the battery pack for the K2, but I imagine I'll run into some objections of this type of battery when I travel on airplanes with the radio and I'd like to reduce the weight by not carrying the battery all the time. Any suggestions? Has anyone tried the MFJ4103? I can't tell from the picture if it uses a 3 prong grounded AC plug or not, perhaps that would indicate some better grounding in the design.. 73, K5GUS Dan Schieler _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
