[Towertalk] Back-To-Back Diodes - Careful!!

[Ward Silver]

> After we replaced the bulb and put a couple of back-to-back diodes =
across the receive antenna input, the unit worked fine.

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.
