;-) I agree and will support you with the new meaning for LF!!

Paul, the new pic is more impressive and shows a big burn... I could send you some pic from my collection ;-)
Just an idea for the new version you are planning.
As far as I understood the mobile coil is part of the loading coil (If I assume wrong discard..) where is it placed? would suggest to place in the bottom part of the coil just to be in the lower voltage environment.

Of course when RF want to burn .. it burns!

Sorry to see the damages Paul. As Chris said very certainly "LF without smoke is QRP" ;-)

I would add that LF stands for "Let's Fire" and a "!" should be added at the end

Eventually I will rebuild it perfect... although I would prefer to start over with a new coil as this one requires too much maintenance. Right now I don't have the luxury of time for any of that. It's solar minimum and I need this thing working. :)

I don't trust the inner coil form for HV now, too much carbon:

So that'll have to get replaced. I will make the connections differently this time!

Paul
