---------------------------- The impedance at the center of a 33 foot doublet on 40 meters will be about 12-j850 ohms. I would expect the KX1's ATU to match that without problem. However, Wayne pointed out off the reflector that I was making a rash assumption: Mike did *not* say he had an ATU! Without the ATU it's very important to provide a decent match to the KX1 output of course. That's why Wayne said to use a self-resonant 66 foot dipole. So Mike, if you didn't include the KXAT1 internal ATU or a T1 external ATU, maybe this is the time to add one! It's not a requirement, but if you don't use one you'll need to make sure to have a low SWR at the rig with any antenna you use in order for it to work very well.
