No, the Corsair does not cover the 11 meter band. A 10 meter crystal on the OSC/MIX board would need to be swapped out with a different crystal to cover that spectrum. The associated 10 meter bandpass filters would also need to be re-tuned. I do not suggest this adaptation because if the bandpass adjustments are not tuned properly, spurious emissions will likely occur. Being that you’re asking about this coverage, kinda tells me you don’t have the proper equipment to make those adjustments. I apologize ahead of time if I'm wrong.
