Re: [Elecraft] 1N5711 diodes in directional coupler

I agree with Lyle's discussion on this. The reason for using 1N5711s is to get low power accuracy. If you are running high power only, then you probably could get by with 1N4148s in the directional coupler, sacrificing low power operation. If you really want to replace them today, you could pr

These are used in the directional coupler of the K2, KPA, and KAT-100. I have lost these to ESD more than once. Several questions; Gary says that 1N5711's give more accurate readings than lessor diodes such as the 1N4148... question; how much more accurate, and how critical is this accuracy?
