Howdy Folks Good news and bad news,Good news first,I just completed K2 4988 and all appears well. Now the bad news, while finishing up 4988 I transmitted into the my Elecraft N-Gen noise generator,and (took it out),Im pretty sure U1 (MAR-1MMIC) was the first thing to go,but what about the diodes,should I order those also? The LED still works : ) 73 W4GNS
