All, I was skeptical that a simple Radio Shack power brick would serve as an acceptable power supply for my KX3, given that many products like this produce RFI and/or have enough ripple in their output to render them unusable for amateur radio purposes. Based on a recent posting, I purchased a Radio Shack "Enercell" AC to DC power adapter, catalog number 273-318 and gave it a try. It works fine. I can get 10 watts of clean output (listened to my CW tone in a separate receiver) and RFI is not a problem. The unit does produce some hash that can be heard on 80m, but it's not very strong and isn't a problem if you are using a coax-fed antenna. I'm not sure how it would work if you were using a long wire connected directly to the rig that runs in close proximity to the power supply. But, for my use, this is going to do the job nicely. Very light weight, and great for portable operation.
