Thanks (again) Evan! For voltage, don't the Zeners give SWR protection that the L14 diode does not give??Do you think doing both Zeners and TN0110/TN0106 is also perhaps belt-and-suspenders?
For power/heat, I'm still working on my TN0110 heat dissipation for higher bands during operation. For?tuning specifically, isn't lowering supply voltage an easy protection?
