[Amps] how to estimate the Q of a tank circuit

[R L Measures]

Johan -- A good rule of thumb is four to one.   For example, if a  
certain wire diameter is rated at 4A at 50 - 60 Hz, it's good for 1A  
at HF,  Also, it is good engineering practice to forced air cool the  
tank L as well as the bandswitch.
