Yes you did, by
George.?? It appears I glossed over it in my haste Jack.? My
bad.
?
Now, to be patient ¨C I¡¯m
assuming you¡¯re still developing.? I recall the picture for sure, but did
not make the
connection with your
message.? Shucks. . . . it¡¯s stuff like this that makes it painfully
obvious how much I do
not know today, still, at 73. Well, it just makes it nicer to
have resources such as yourself.

Just to show you I did find
it:
***
Was on vacation with no
internet...a promise to XYL.
I used the
MAR-3SM+ part for the antenna analyzer (AA) project because it's easier
to find. Right now, I'm using the same AA board for the display/VFO and it seems
to be doing well taking the VFO output via RG174 to Farhan's input pins. That
said, Farrukh is redesigning the board to bring almost all of the Arduino Mega
2560 Pro Mini pins out to header pins to make it easier to experiment with the
BITX40 (I'm lazy...B40). You can see pictures of the AA board that supports the
AD9850/Mega and the TFT display by looking at the assembly manual on QRPGuys.com
(look for the Antenna Analyzer menu option). The beta for the new board is being
tested and I would guess it will be three weeks before we have the "real" board
done. I have the code done so that it will autosize to a 2.4", 2.8", 3.5" and
3.95" mcufriend.com TFT displays. That should give some case flexibility.
?
Dennis Kidder (W6DQ and my co-author on the Arduino Projects book) is working
on a CW and AGC options for the B40. I'm working on the code for a capacitive
touch keyer (from the Projects book) which will do away with the need to
drag a paddle with you. Setting CW speed and other menu options as well as
tuning it done via a rotary encoder. The code provides for three CW messages to
be tied to 3 NO switches on the top of the case. Each switch is tied to one of
up to 50 canned messages (changeable at runtime). Press one of the switches and
that message is sent via CW. The currently-selected message is displayed at the
bottom of the display. It also monitors input voltage and has an S meter. (A
repost of the display is below.) I don't know what we'll charge for the board,
but it is a little bigger than the AA board to accommodate the different display
sizes. All I can say at this point is that it will be less than
$10.

Yes, and I have posted a picture of it before.

Hello
All,
?
Just a
curiosity question here.
?
Has anyone developed
a color display for the VFO showing S-meter, modes, PO, etc?\
for the
BITX projects?
?
I¡¯ve seen references to such a display, at one
time or another, you tube and the like,
but no real project info or perhaps info on a
related kit.
?
So, thought I¡¯d ask and see what
results.
