One needs enough Q to be able to obtain the needed transformation and to
sufficiently attenuate harmonics. . Eimac recommends a Q of 10 to 15.
10M is a special case due to the anode-nearest grid C. As a rule of
thumb, the proper amount of tank L for 10M is that which will result in
the Tune-C being about 10% meshed at 29.7MHz.
