Hey there Elecraft! I just noticed that D18 on the back of rf bd got fried. The diode looks melted in the middle, and is probably not useable. Now here is my question, and I feel silly even to ask, but, can I just go to Radio Shack and pick up another 1N4148 diode, or is the diode provided by Elecraft specific for this kit.
