jFarley, I found the ideal OpAmp for your next Loop Antenna Preamp

I've got an altimeter from an old B-17 if you need one, Farley. No analog to digital input/output on the thing but a CalTech man like Al ought to be able to slap one together from a digital tire pressure gauge and a couple of finely crafted gum wrapper capacitors.

Knock knock....Is this thing on?  

Yeah, I guess so.

Thanks, Chris!  Joosta wot ima luke!  These will drop right into the next project, and has supplanted the datasheet for the National LH033 Fast and Damn Fast amps as my fave datasheet of all time.  I'm calling for samples today!

And Pigmeat, I appreciate the offer for the gum wrapper capacitors.  But I have purchased some NOS Hi-Q Russian reflux capacitors (Putin Signature Series) which will be used to resonate each element in a 4 element Backfire Array.  Because I will be using reflux capacitors, I will be able to resonate the loops in both the Frequency AND Time domains, which will of course allow me to hear beacons and other things which have been decommissioned years ago.  It looks good on paper, anyway.

But will it pick up WABC inside the Mt. Kisco A&P supermarket?

That is the true test of any RF device. Speaking of the A&P, did you know lids from cans of Pringles Potato Chips can be used as makeshift knobs for your SDR's so the other dx'er's strolling the aisles won't make fun of you?

The max pd chart is quite telling.
