NE4040B Project..Some Questions

k6whp
 

Chuck,

Wonder if you can answer some questions I may have missed in the existing threads on this project, principally:

(1) Will this be the same M.O. as the NorCal 40A Silver Anniversary project with the Gerber files available to send to a PCB house?

(2) If so, what's your approximate ETC for the Gerber design files?

(3) Will you be doing a series of videos on this..

(4) .. or will you be working off a "pilot document" as a base for building?

(5) Assume it will be possible to build a 20m version of this.

I know you have wrapped up the 1-Watter 17m and Diz's Universal Receiver videos and a lot of us have been nurtured enough to both scrounge and build with the mutual help available from each other, so I don;t want to goad you into feeling as though you have to.

But then again, if you like doing that, we appreciate your efforts.

Project has been hinted at and not formally announced.
It will not be ready for prime time until late Sept or so.

1.? Yes.? Gerber files will be available for sending to board shops.
2.? Completion planned in late Sept.
3.? Videos will be done.
4.? Will use LaTeX to create a complete document on the project.
5.? Multiple bands will be planned, since you can use LC combos
???? made up from different toroids and cap values.

Again, this is a project for later in the year.? Just wanted to see
if there was going to be any interest.? Lots of guys are no longer
building.? And there will be no parts kits available and this will be
do it on your own kind of project.? PTH parts only.

I recommend for all that have interest.? Search your library and
the Internet for NE4040 info and look at what you would do.
We will rename the project AZ4040 later and hoping for a price
break of $40 USD for board (100mm x 100mm hoped for) and
also hoping the $5 per 10 boards will be still be offered by one of
the Chinese board firms.

I'll get a preliminary list of general parts to get from ebay in
Sept.? I'd recommend a large assorted collection of 1/4W
resistors (I like the metal film) and mono caps to start.? Hoping
the tariff wars do not kill off building projects for me.

Chuck,

I consider your response the mother of all hints! Put me down as interested. Combing back pubs now for NE4040 docs now. Also like your swapping out the xfmr cans for toroidal transformers.

Thank you!

William,

Not my idea.?? The transceiver started out with only the use of toroids.
It was one of the ways in which Dave Benson kept the cost down for
the transceiver.

In the files section of [email protected] is a directory 'NE4040
Project TBD' that was started some time ago, but lack of interest
at the time delayed the project.

Now that I have the PCB software figured out, I've decided to get
crazy with a number of old in the queue projects.

BTW, the 68B09 SBC Computer is not an S-100 design or a
revival of same as some one posted, but it is a project resulting
from the use of the PCB software.

thanks,

Chuck,

You are correct of course. I cross-circuited memories from my old CP/M days. Had a huge pile of Micro Cornucopia and All of the the KayPro Profiles mags. (Anyone know Jeff Duntemann, K7JPD? He was the editor.)



When I left off of programming my KayPro 2X (Darth Vader's lunch box), I was working on CW reader software in C.

Those were great times.

William,

Now that is funny.? I'm referring to the attachment of the Z80 system from
Digital Research of Texas in Garland.? I worked with Jim Tanner (Tanner Electronics
in Carrollton TX)? where I bought all my stuff
while living in Dallas and Bill Gates (B.G. Micro).? I wrote a memory diagnostic
routine for several systems and published in Dr Dobbs.? Small world.

I know a bunch of QRPers that used to shop at Tanner Electronics and probably
still do.? I bookmarked the page and will later run through the stock.

I had an assembly language book written by Jeff back when I was teaching assembler. Man, that was decades ago!

Wow, my old Bigboard...

I bought the bare board, made mods (64k rams, video glitch fix(?), data seperator(?)), soldered all those pins...
Subscribed to Microcorucopia...
Went to some home brew computer club meetings, were really jealous of guys with those cool Kaypros...
Those were the days!
