RE: LF: LU1DOW soon in MF/LF

[VIGILANT Luis Fernández <luis@vigilant.es>]

Hi Chris, LF

Oscar answered the question. I'll try to translate, but can't promise not to 
make a mistake in tube terminology :-)

He is not using filament choke as this is a direct heating tethrode. So the 
midpoint of the filament transformer secondary is connected to ground
The driving is to the grid with a tuned circuit. It works in C class for QRSS 
and B Class for DFCW. And YES, this a dangerous high voltage bricolage
and a waste of energy. Just the filament is sucking 35.5 Amps :-O

Oscar plans to test first single carrier in LF with LU8YD at 1000Km first to 
check if all is going as in previous tests some time ago. After that he will 
switch
to MF and test again
