LF: Re re Xtal Osc "delta tuning "

["Lawrence Mayhead" <laurie@g3aqc.freeserve.co.uk>]

Yes Bob I realise that I am pushing things rather a lot, hence the big shift
in emitter resistance ,
however it does work and others may be interested.
Regarding the mechanism behind your idea could it possibly be a form of
Miller effect as in valve
technowledgy ? perhaps the base emitter capacitance depends on the emitter
current.
Hopefully someone oin this group more knowlegable than me can comment.
