At about 7" x 6" x 2" tall that's a pretty big item to 3D print IMHO Ken, N2VIP

Re: uBITX Display Separation Cable
Great idea Al !?
I think it will be much easier to mount things with the display?
physically separated from the main board.
Cheers
Michael VE3WMB?
P.S. I am doing the happy dance as my order made the cutoff for the first batch of uBITX?
kits.?

Re: uBITX Display Separation Cable
The BITX, whether u or not, can benefit from this :) . Makes for more case and panel options.

If he follows his
usual approach, Sunnil in India is likely to produce a custom
case for the uBITX, as he has for the BITX20? and BITX40. His
prices will be difficult to match, I suspect.

Hello all,?
I'm new to the group. I was sent here from a where they were
talking about a case. I work as engineer/drafter at sheet metal
fabrication company. We design, manufacture and powdercoat all
sorts electronic enclosures for customers.
If I made the cut-off, I will hopefully be receiving a ubitx
soon and I will be designing a case to fit the ubitx. There is a
possibility of mass producing cases. It could something along
the lines of
but designed with stand offs for the board and screen, speaker
cutout (we would have to agree on a speaker) and powdercoated
mini texture black. Once I get a design I could get it properly
quoted and let you all know the price. Of course it would have
to be on a pre-order basis.
Price will obviously be effected by demand, the more that can be
made, the cheaper it can be. Other cost savings would be the
removal of press fittings and coatings.
Let me know what you think

Ashhar,?thanks for bringing the uBITX to the world.?
A quick question - I ordered and paid for one on Sat, 9/12/17.? I haven't received any comms about it so far. Do I need to enquire about it ? or just sit tight and wait?
Thanks

RCA connectors are readily available, inexpensive, and work quite well.

I don't know why hams are "stuck" on the inferior PL-259
plug and SO-239 socket. Well, I do. It's because manufacturers
keep sticking them on the back of radios and we don't insist
that they stop using them. For a small connector, I would
prefer SMA. BNC is "OK" but the bayonets wear out if you
you connect/disconnect them enough times. For a "large"
connector, the N connector is superior in so many ways.

uBITX Display Separation Cable
While waiting for my uBITX, I decided to try to come up with a way of mounting the main circuit board at the rear of a metal case so I could use the rear panel as a heatsink for the two IRF510's (with insulating hardware).?The raduino must remain plugged directly into the main circuit board, so the only way to move the LCD display forward if required is to make up a display separation cable.I found that a discarded computer IDE cable does the job. See the details here:

I got both ant
connectors on my case.
I used the small Jameco
black and white enclosure.????? It is almost too small.? You
drill either the biggest drill you have and file.
Or, go around inside
your big hole with 1/8", try to get the center out, and then
file.
A warning on the Jameco
case, the bottom is Al, but the top steel.? I had to cut a 4"
circle for my speaker in STEEL!
I used a fine metal
blade in my sabre saw.? Cover everything with Duc tape first.?
I was not fun.?? Thank heaven for variable speed.? Then I used
a half-round big file to go to the circle edge.
I got 2 of the plastic
cases suggested here on Bangood for $8 ea.? They took a month
to get here.
I am going for one of
those for uBit.?? If it fits?? I am going to paint them.? They
are too White.

Gordon, the point of the case is to have all the holes cutout.
Otherwise it would be much cheaper to purchase a prefab case on
banggood, hammond or whever and layout the cutouts yourself. I
will have it quoted using 0.060 Alum (1.5mm) or 18ga Steel
(0.048"/1.2mm). Currently the cost of aluminum per pound is 3x
more than steel. I would consider galvannealed as well.?
Of course I will be posting 3d models and drawings for everyone
to look over. However, person wants their unique case built to
the way they want it but that is next to impossible unless you
want to pay heavily for it which I don't think is beneficial for
a $120 radio. I will consider everyone's input as well
Only questions I would have at the moment is a specific speaker
that would be used and if they would be using a BNC or SO-239
chassis mount.?

Also I hope that we will soon see a place for only information on the the uBITx
/g/BITX20/topics

I just ordered my uBITX which as I understand is back ordered.? When I get it and get it assembled, I will be designing a 3D printed case for it.??
Also I hope that we will soon see a place for only information on the the uBITx 3 to 30 Mhz version.? Since I signed up I am getting tons of e-mails for the 20 and 40 Mhz versions which I hope we will soon be able to click on something to stop those from coming.? I am only interested in the 3 to 30 Mhz version.

The rotary encoder that came with my uBITX does not have mechanical detents.? It is free-running.
Rotary encoders that I got earlier from Ebay vendors look the same but they do have mechanical
detents.? Some have one detent stop per 2 steps and others have one detent per 1 step.? The
2-step types require a slight software modification to make them work best for tuning applications.

Re: BitX40 Builders Fest opportunity to see what others are doing and compare notes, and some surprises

These have your name on them
if I can find a way less expensive than the cost of a ?BITX to ship them to you. Which I haven¡¯t found.

Re: SDR dongle for spectrum analyzer with signal from Bitx40?
We'll have to see if we have enough pico-acres available, but we already have the code for it available from a signal generator project.

It amazing just as it is!! Been listening to 40M CW while I work on some photos I took. I swear the receiver is as good as my FT-1200.

Inline image
It also assumes the BITX40 CW mod, and provides for 3 external "message switches" that allow you to send stored messages from a list of up to 50 messages (useful during CW contests). The board is designed to work with mcufriend displays ranging from 2.4" to 3.5". The code also provides for an off-board RTC, too. The PCB only sells for $8, including domestic shipping. The assembly manual is available in the Files section.
Note: Al Peter (AC8GY) and I are redoing the board for the ?BITX. It's still being designed but we're pretty sure we will use the Si5351 and either the Teensy 3.6 (Arduino compatible) or the ESP32. The screen will likely be a 5" color touch screen and we will likely bring the pins out to headers for experimenting. The additional resources and enhanced computing power brings a lot of computationally-intensive options into play. Since Ashhar has made the rig multiband, the screen info will be expanded from what's shown above. We are making concerted efforts to keep the price of the board down while maintaining its high quality. As always, the code will be Open Source. Al's just moved into a new home and the Holidays have slowed us down. It's too early to say when we will be ready for Beta testing.
