Mr. Ehrhorn says there is no evidence. Thanks to N7WS, there is
evidence. Now that the evidence is there, Ehrhorn is silent on the
matter. He apparently does not like to admit to making errors.

On 6m, air-core chokes work well. Air never saturates.

True.

50-ohms of XL should be plenty.

Keep the lead from C-tune to the anodes as short as practical. Add some
vhf loaders at the cathode. These are roughly 10-ohms in series with c.
30pF, from the cathode to ground. They load the feedback path.
