Hi Bone,
Looks good! What did you use to do the layout?
The MR-6 isn't the best design to start with but your layout looks much nicer than the R*A*M*S*E*Y one
If you want to keep your board single-sided then swap C1 and C2, moving the RF decoupling cap closer to L1 and L2. I think the MR-6 uses a double-sided board, if you can make yours double-sided then connect the emitters of the RF transistors, and the ground ends of C11, C9, and C2 (once you've moved it to where C1 is) straight to the ground plane, loose the ground track make it even smaller
