Re: #sbitx upgrade kit 2 is on the way
#sBitx
First I am very grateful?for how Ashaar and Thomas have supported this effort going above and beyond and not asking a penny for the upgrades, thank you.? But I do not understand the delay.? I have received many christmas?cards and packages from NJ in the last week and from the postmark none of them took more than a week to get here in TX.? I don't understand the delay.
Hi All,
Merry Christmas!? I hope everyone is out of the snow storm in the US.
Quick question: Has anyone received their upgrade kit?? I ask because Thomas stated that kits were sent out on 10 Dec.? It might be normal Christmas time delays but I've not received one and I was curious if anyone has.
Thanks, Scott

Re: Best Source for 5vdc on uBitx v6
#ubitxv6
Hello Doug,
I have done the mods that you are looking at on a V6 with a 2.8" Nextion display.? The stock 5volt regulator was used, taking the 5 volts for the S-Meter amp off the encoder pin connector on the Raduino board.? I would not recommend the Raduino regulator as the source to power another Nano if you are looking at that solution from KD8CEC or going to a larger screen.? For either case, I would add a second 5-volt regulator mounted to the case to dissipate the extra heat.
An alternative might be a switching regulator for all of the 5-volt power mounted in place of the 7805, the stock regulator.? That solution is being used on the sBitx, so I would assume that RF noise is not an issue.
Have fun with the mods!

Ratnabh,
It might be RF feedback.? This happened to me with my first uBotx.? The solution was grounding, A common mode choke on the line to the uBitx from the off-center fed dipole to the shack, and some snap-on ferrites on the mic and power cables to the uBitx.
Just a suggestion.

It should have been "first uBitx," not "first uBotx"

Best Source for 5vdc on uBitx v6
#ubitxv6
I'm working on a few uBitx v6 mods (AGC, S-meter, Nextion, etc.) Most need a source of 5vdc. Some folks are taking 5vdc from the Arduino Nano since I don't think there's any 5vdc on the main board. Does anyone know how much current one can sink from the Nano? Is there a better solution? (I could add a 12-5v converter.)

A 3d-printer designed test bed for the uBITX
As I port KD8CEC to Raspberry Pi Pico, Teensy, and the newer members of the Nano family (Every, IOT, BLE, RP Connect), I discovered that the shear volume of combinations of processors and LCD far exceeded any budget my xyl would give me (both $$$$ and sq meters). So i needed a design where I could get easy access to the mother board to unplug and plug in different Raduino/LCD's. (This exercise resulted in several bug fixes to the original code!).? So I designed one... The models and stl are at: But let me add some photos so you can see what trouble I got into....?? 
Face view? 20x4 LCD. Notice the open area to the left to plug in USB cable for I2C Nano
 Top view - Notice dual 5V power supply + board for the I2C Nano on the left Speaker grill - And Yes I have a habit of poking my fingers through speakers... A little known feature of KD8CEC (and perhaps not useful vs the 20x4) is a dual 16x2 LCD connected via I2C My Raduino rack...73 Mark -- AJ6CU KD8CEC 2.0, Nextion Screens,? and open source uBITX Raduino boards for Arduino IOT, BLE, RP2040, Teensy 4.0, and Raspberry Pi Pico https://github.com/aj6cu

Re: Re Run Of uBitx Enclosure
Believe the 7" has the same resolutions as the 5". At least when i created the 7" "tft" that looked like the spec in the Nextion editor.
Several 5" based designs that were just re-exported for the 7 are at:?
There was another comment about somebody buying a display at buydisplay.? I *assume* the plan there was for the "standard" uBITX firmware and *not* the Nextion based KD8CEC.? If that is true, then your comment about resizing might be very true (never looked at how the OEM firmware manages that touchscreen.

Re: Re Run Of uBitx Enclosure
Just remember you can not just resize the screen you have to redo the math for the meter sections to display correctly . Else you will have incorrect readings.

Thanks Peter . Yes last time we missed making the 7 inch display case. Since I already have a 7 inch Nextion so I thought it would be to try a limited run for it . Thanks for your interest. We require suggestions for any new color for the enclosures.

Re: Re Run Of uBitx Enclosure
Sunil,
You might look at the T41 group and see how your enclosures could also be used there.?

Re: uBitx Keeps Switching Sidebands

The WSJT-X program sends a CAT command to put the radio in USB mode as most FT8 activity is on USB. This can be disabled using the Mode setting on the Radio tab of the Settings dialog.

Re: Re Run Of uBitx Enclosure
I'd be interested in one of these with 7" Nextion face.?
It might be worth considering doing a limited?run for the 7" buyandisplay displays as they are quite popular with some homebrew projects, if advertised in the right groups I'd say you'd get some takers for sure.

Lately I am getting inquiries for our ubitx nextion enclosures. So it's been decided to re launch them back .?
So we will have the 2.8, 5 inch and the new 7 inch nextion display case with our old popular agc circuit . We may substitute the analogue meter with the oled display meter. But the the space available could also be used for analogue meter .
We are also thinking of adding fitting for? the WA2EBY amp? and 100 watt Automatic Antenna Tuner to the enclosure.
The enclosure would be interesting with the ubitx and what ever firmware is used .?
I would be glad to hear any feedback or suggestions on the enclosure design .
It gives me immense pleasure to provide our products at inkits which we have been doing over a decade .
In this coming new year we shall be coming out with some new products .
Thanks and best wishes?

HC49U crystals look like this. The S version is a short version. As Ashhar mentioned, grounding the case may have little effect on bandwidth. I wouldn't worry too much about it. Just make sure you get fundamental and not third overtone crystals.
Thanks for the help Jerry. How do I know if I have HC49 crystals??

Re: uBitx Keeps Switching Sidebands

Maybe not an answer, but FT8 on 7074 use USB, not LSB. Maybe is that a reason. WSJT-X set rig to USB.

Aaron, The crystals have four pins of which two can be grounded, you can leave them out as well. I havent noticed much difference either way. - f

Type HC49/U/S cases can grounded by soldering a wire to the top of the HC49 case to ground. If they're smd crystals, they usually have a couple of ground pads.
My health is still hit-and-miss but I need to get some progress on my sBITX. I look at the schematic and wonder if I have gotten in over my head. I think that building the sBITX for my first homebrew project may be beyond my reach. I have a couple of questions (for now) concerning the crystal filter schematic above.?
1) All of the crystals that I have seen have two leads on them. In the schematic above they have 4 legs. Am I seeing this correctly?
2)What type of jack is J7?
