Now you have given me something else to do (the list gets longer everyday!). I'll have to read and try to understand the article now.
thanks Gary
No worries Gary, I'm not very good at writing posts.
I think that guys (He's called Vlad) approach was to combine the properties of two oscillators ie: the Vackar and the Armstrong, we already know that one of the most common types of regen detector is the Armstrong type, ie: the amount of regen required for oscillation increases as the frequency being tuned decreases, I presume that the Vackar helps to compensate for this, the Vackar is relatively stable in amplitude and frequency across a wide frequency range ie: 3 to 1.
He refers to "tilt" this as far as I can understand is his word to describe the amount of feedback required in plus or minus terms around a nominal value as the frequency is increased or decreased
That's how I have read it so far, I might be wrong so any input welcome.
Lawrence.
