Hi, I have built the cascode amp using the the ka7exm board. I am have some trouble shooting problems, does any one have the correct operating volatages for Q1 and Q2? I do not think the AGC circuit is working properly. I am getting only about 1 vdc one the emitter of Q1. Any help is appreciated. TNX and 73 John-Ke1IH

Hey John, If you can wait until later today, I will try to find my HYCAS and make those measurements for you. Do you need any others? What exactly are your symptoms.I know mine worked just fine because I am going to make it part of a home brew 6M rig. I do not remember the AGC's dynamic range but, 60Db sounds familiar to my senile mind. BTW, I grew up in Willimantic, CT not far from you. And, I lived in Westbrook until 1985. Then, I moved out here to Amherst, OH after taking a job in Lorain, OH. I have backpacked and paddled most of New England and I sure do miss it....but, I do not miss Conn.'s taxes !!!!!! All my family is still stuck in that highly taxed and crowded land. I wanted to retire in Northern New England. But, life did not take that turn for me. Be back to you soon. 73, Bob WA!FXT
