Good Morning Everyone,
My sincerest of thanks to all who responded to me directly re. my dilema with
fixed padding capacitors of the mica/ceramic variety going "south" on me on
160-meters...
Based upon the facts so garnerd, I've pressed ahead & incorporated a scheme
whereby a fixed vacuum capacitor --- in tandem with a second fully-meshed air
variable --- shall supplement the "main" air variable plate tuning cap in my
2x813 linear. It's already been retrofitted, & the bench testing shall begin
this morning, before I (hopefully!) can batten down all the hatches of the
enclosure for the next while...
I have one favour, however, to ask of the kind gentleman who offered me
detailed specifics on HOMEBREWING fixed capacitors, utilizing teflon sheets as
a dielectric: might I please prevail upon you to RE-SEND your message directly
to me? I had every intention of saving your communication aside for the moment,
& getting a hard copy of it later on, for future reference...unfortunately, I
can NOT for the life me locate your note, & I fear now that I may have
inadvertently deleted it! (stoopid me). The notion of making my own inexpensive
transmitting caps has always intrigued me --- in fact, some years ago I toyed
with the prospects of making compact units using glass microscope slides and
brass shim stock...but that was merely a dream, & you have obviously "done the
deed" A-OK, & I would dearly like to re-read your thoughts & methods again, if
I could...
Once more, many thanks to all who responded, & I can only hope that I did not
neglect to personally send each of you a note of thanks...
~73!~ Eddy VE3CUI - VE3XZ
