Charles,

As always, thank you for your insight and thoughtful comments.  I really
liked your past analysis of the choke input power supply.

It looks like you have thought a bit about the problem of ramp up,
certainly more than I have.  I could not see an easy way to do it from the
power supply end, which would be part of the point.  If I were going to do
a lot of work, it would probably be to design a switching power supply, and
I'm not ready to tackle that one today.

I decided to move onto the main point, which is getting a working radio.
