Danger, Will Robinson! The back-to-back diodes are terrific harmonic =
generators and mixers. If you have strong local BC stations, you will =
cause yourself a lot of grief as these little guys generate their mixing =
products. Also, if you're in a multi-transmitter environment, the local =
interference they generate will also cause a lot of trouble. If you =
have neither of these to worry about - no sweat - but remember they are =
there.
