Wilson Relic & Coin 1V

[dbanner]

I found an old schematic drawing, and a HP engineer friend of mine, put in what he thought is the correct chips numbers. So check it out and see it they work for the chips. Okay, I managed to finally attach the .pdf schematic, with the unknown chips names. Now I cannot guarantee that the chip numbers are correct. But you can try and replace it with these chip numbers, and I think it will work...

Hi Melbeta.
You've got vaccine no doubt.

Here in Trinidad it's tough going. We're struggling with the sinopharm vax, which is a sick twist on the whole matter, truth be told. Talk about the irony.
You know you're living in the third world when.... better I not go down that road.

Anyways, it's unlikely that the RX chip is a 741. I would think Wilson engineer wouldn't approve.

Back then the MC33077/78 were popular for preamps (low noise, wide bandwidth) but they are duals. I'll guess at the NE5534 for the preamp.
The audio driver is definitely not an LM393, it's an opamp, pinout suggests it's part of a quad so likely one of the LM324s.
The derivative opamps (last 2 on the lower right) have their +/- signs backwards. This looks like a Bill Lahr schematic.

VLF710 model shows NE5534. i do not remember who gave those pics.

Yes, the s.o.b who uploaded those pics got me all jacked up kt315. I actually reversed draw the PCB, but unfortunately, such s.o.b's don't care about us trash to treasure people. Why? Because the vertical PCB is ......
There a some things in life one has to accept, such as dumb people.
Those s.o.b's all ways do the same thing over and over, and then they depart the planet, no richer for their troubles.
I recall some stupid guy putting some pics and an incomplete Sprint layout which I completed, just a little bit of consideration in naming one or two components, and verification. That s.o.b never bothered to thank the dbanner.

I really feel the world is closing in. I know for a fact the reason for Carl's obliteration of the off topics forum. He simply caved under pressure. I don't blame him, he's weak. I for one will never be subjected to communist rule, I'd rather die. The FBI can suck my FPGA.

Stay on topic, I spent a lot of time sorting out the bul**** in my mind, the fact is we are analog species. Go live in SA gwil, then you'll be changing your tune.
The colums and rows I'm disinterested. Machine code can bridge the distance for the dim witted.
I'm interested in the nitty gritty, as far as my my mind can hold.
For example, the noise floor. The intracacies of layout. Let dbanner go in his bed. I will have much more to say on thie subject. I'll upload the Sprint layout of the previous pics.
And just for the sake of interweaving free speech, Marilyn Monroe was and is the most beautiful woman I've ever seen,albeit post mortem. That woman just wants to make into a cmos chip. Ain't she stunning.
