Good luck, and let me know how ya do.

I'm TALKING about CW   Didn't know you had voice privledges down there.  
And, I'm pretty sure that the bottom of the Extra class sub-band is 3750kHz.  
Below there, it's CW for the States.

RF Choke.  It looks like it's wound on a resistor looking body.

Thats the great thing about hollow state outputs - they're MUCH more 
forgiving than their solid-state counterparts!
Give me a pair of 6146's ANYday!
