What's really fun is that you can adjust the AGC slope on the K3 in the config menu. In fact, if you do this while listening to a very strong signal, you can hear exactly what the AGC does to reduce the gain while you are making the adjustment. For this contest, I put in the maximum degree of attenuation, which helped control the strong signals. 73, Andy, AE6Y
