Armstrong Q multiplier.Works fine, if you add C2 to reduce noise you may get some slight odd effects but mostly harmless ones!I did a blog post but I don't want to litter the forum too much with those.
Where is the blog post?, and where should I pick off the link to the 455kc IF
Details about the T3
I am just about to launch into building a Q multiplier for a Drake 2B
Thanks
