Making nice labels for the front panel of the µBITx may not be all that intuitive. Many of us use a label writer (e.g. Brother or Dymo device). The best options (depending on your front panel colour) may be to use “black on transparent” or “white on transparent” tapes.
Vic WA4THR was looking for a way to easily label the front panel of his BitX40 and was pointed to the use of an Avery product. It is a transparent plastic with an adhesive backing and you can print using either an inkjet or a laser printer. You then just cut the strips where you designed the label, peel the backing, and place on the panel. Really easy, and the results are pretty good. One sheet can produce a ton of labels, too. The product is Avery 4397.
John WA2FZW uses the same product, but makes one big decal for the entire panel. That way you don’t see the edges of the individual labels. There is a full description of the process used in the documentation for his Magnetic Loop antenna controller.
Dave G4UF has another method that he uses. You don’t have to be as careful with the LCD cutting 🙂
And then Dan, W2DLC told us that he printed his out on with an inkjet printer on regular photo paper and then put some clear tape over it to preserve it with a pretty amazing result:
AA9GG adheres his printout to the case using a sheet of 3M adhesive. Basically, it’s a large sheet of double sided tape.
Daniel W2DLC uses “Loktite” spray adhesive.
This is a rather nice µBITx build from Dennis N8GGI.
Dennis says, “Finished wiring up the UBITX today and downloaded the KD8CEC firmware. I took my time with the case. Old retired industrial designers still like to design (and build).
“I added a keyer circuit which has a speed pot…I don’t like to run through menus to match someone’s speed. I also added a Hi-per-Mite audio filter which really makes it a nice CW rig.
“First 40 meter CW contact was New Hampshire from my QTH on Lake Erie in north central Ohio. Second 20 Meter CW QSO was from Portugal getting a 559 report using a tri-bander at 60 feet. I tried 20 meter SSB and worked the gulf coast of Florida with a 5×6 report. It’s a great little radio! Now I still have to tackle the TX pop and try to tame down the sidetone volume issue. I hope the 1,500 watt linear doesn’t get lonesome from lack of use.”
And what lies beneath the paint! The “see-through” version! Dennis says, “Kinda looks like the old ‘visible V-8’ from the ’70s.”
Sunil VU3SUA is providing extra PCBs with his uBitx case.
See http://amateurradiokits.in to purchase the case and PCBs.
1. Encoder PCB
This pcb will save you from the clutter of wiring up the encoder.
2. USB.D9. PCB
Use this board if you wish to. if you do not want to use this board then cut a small plexi glass sheet and close the open area.
3.Power Connector PCB
The DC Power supply connections are easy to install with a board to assist. The On/Off switch, Fuse, IN4007 diode and power connector are mounted on a small board again removing wiring clutter.
Care has to be taken in mounting the On/Off switch, as excessive use of soldering heat or bending of the pins on the switch may damage it.
Sunil says that he will be making further improvements in the µBITx products to make it easier to wire in kit components into the case.
Bill KC5SB has been using his “black beauty” µBITx on the FT8 digital mode and has already worked a station in Brazil with no problems. Bill has installed a fan because he spends a lot of time on digital modes. The display has been replaced with one with a blue background (goes better with black) and the unlabelled switch on the back is for the fan – high, off, low.
The case can be purchased here. It has, of course, been painted.
Nigel G4ZAL has just finished his µBITx build and modded it a little in readiness for adding additional boards/hacks.
He cut the track feeding the TDA2822 and fed it with 5v from a little Radio Control UBEC. At the same time, he removed the 5v regulator on the Raduino and fed that from the UBEC as well. You can see from the photos that he has added a little ‘bus’ for picking off further 5v supplies as required.
His installation looks pretty snappy in the well used Banggood case
And the µBITx is already hard at work on 40m using the FT8 digital mode:
Nelson KG7GYS has built his µBITx into “a box I had bought for some project over a decade ago and never got around to using”.
He ordered a speaker grill from Amazon for about US$2.50. He decided, like many of us, to use a pot with switch from his junk box in order to have a standard size shaft (it came out of an old Radio Shack CB set). The knobs are from an old Henry Tempo One (Yaesu FT-200). The speaker is from his junk box, as is the 12vdc fan.
We all want to know what the heck all that test gear does!
Vince, N2AIE, worked Tom VE3THR and Bill NG1P tonight on 7.277 out of his QTH in Cedar Rapids IA. These were his first uBitx contacts with other uBitx and bitx40 rigs.
Vince has loaded (after some angst) the KD8CEC firmware, and has the rig interfaced with Ham Radio Deluxe (in both directions). His rig also has a 3.5in touchscreen Raspberry pi for digital modes built in on the right hand side of the front panel as illustrated above.
Take a look at the rear panel of his rather attractive build:
Joel, N6ALT, has declared that he “is done with his µBITx”. And we can see why! This is a very nice build in a very classy case.
After three attempts at different enclosures, he settled on this one from China. https://www.ebay.com/itm/
The PTT switch is mounted in the pen housing on a small piece of perf board.
It is built very well and super light. Only 4 screws hold the whole thing together yet it is very strong and rigid. Very ingenious.
The radio weighs 2 pounds. Joel did not leave the display mounted to the main board as it would make the display not centred and too low on the front panel. He built a short flat extension cable out of a female and male header.
Sunil VU3SUA who is an active BITX20 list constructor has a business (Inkits) selling enclosures and electronic components for the Indian domestic and international market. Sunil is now shipping his µBITx case. This is a high quality metal case that is available in several colours: Maroon, Black, DA Grey, Siemens Grey, and Blue.
As you can see this is a very professional looking case. The case will be in high demand initially and is, therefore, only available on pre order.
Sunil’s website says that the first batch of pre order bookings has now ended and shipping has started (15th March 2018).
We should see reviews of this product shortly on the BITX20 list.
Bookings for the Second Batch of pre order booking open now. The shipping of second batch will start by end of March or Starting from 1st April 2018.
The universal case for the µBITx costs US$34.99 with worldwide shipping via India Post costing US$20. For a DHL courier service there is an additional charge of US$15.
Orders will be shipped in order of bookings.
