Re: Introduction / Newbie Questions

 

Reed,

Thanks for the reply and the information. I will take a look at your branch. I'm always willing to learn.

I'm not sure I understand your comment that 6.3.1 is older. That's the software I downloaded from GitHub using the link an Ashar's website. Did you mean newer?

Thanks for the KF2510 info.? I didn't know the name of the connector. I found a kit on Amazon.

Yes, I see the 5v comment in the item title, but at the bottom of the full product description it says:
"Note:
If you are using this LCD with a 5V device such as an Arduino, be aware that it doesn't work if WITHOUT level shifting to 3.3v logic. Please use level shifters from 5V to 3.3V, it will work then."

I'll look into the rotary encoder options.

Unfortunately, the wires are cut so close to the connector that there's nothing to solder onto. I might be able to remove the pin and replace it with a pin from the KF2510 kit I just ordered.

73,
Mark
Re: Forgot one question

 

I picked up this switch, which I leave off, so that the 5V from my computer is disconnected, but ground and data pass through. Looks like it's out of stock right now, but you could look for (or make!) something similar.

Re: Introduction / Newbie Questions

 

Oops! Forgot to answer your SD card question. If you look at the screen's board, you'll see that the SD card signals are on a separate header that is not hooked up on the Radiuno/Arduino side, so no, you cannot use the SD card without making modifications.

Re: Introduction / Newbie Questions

 

Hi Mark,

Not sure if these answer will all satisfy, but I'll take a shot.

Software:
6.3.1 is older than the version that shows 6.1 on the screen. The main difference is that Ashhar drastically improved the screen draw speed. If you're looking to tinker with software, you might take a look at my branch, since I've tried to sort the code by function, and fixed a number of issues with the stock software:

Connector:
A search for "KF2510" should get you in the right direction, I think.

Display:
Maybe I'm missing something, but a quote from your Amazon link:
"5V compatible, use with 3.3V or 5V logic"

Rotary Encoder:
There are lots of options. If you search this group, you'll find plenty of suggestions, including higher precision/count options, optical, magnetic, etc encoders. I don't know the exact part included in the kit, but Jim suggests those one: /g/BITX20/message/45085

Digital Interface:
I think the wires on the v6 kits are cut so that people don't accidentally connect their encoders wrong. You probably want to solder onto the stub or replace that wire with a new crimped wire if you want to connect to it internally. No reason you shouldn't use the mic jack instead, if that's more convenient. If you look at the schematics, you'll see they're connected to the same place.

CAT:
I have some settings in my software manual that have worked for me. I'm not sure why you'd have a mismatch, though, even with stock software.
Manual:?
Demo:?

Keying Line:
There is a "TX" net that is powered only when transmitting, so if you're trying to activate something when transmitting, monitoring the "TX" net is a good bet.

Hello, Mark
Normally it is not necessary to disconnect a USB port before turning off the slave or the master, but with the Raduino of the UbITX it is better to disconnect the USB from the transceiver, to avoid any unwanted action from the PC to the NANO,
Obviously only for the total security of the management software and EEPROM data of the uBTX.
Generally, nothing should happen anyway.
Greetings IW4AJR Loris
Forgot one question

 

I notice that when I turn off the uBITx (volume control knob), the display stays on if the USB cable is connected. The arduino is getting power from the USB cable. My desktop computer keeps power on the USB port even when the computer is turned off. Should I disconnect the USB cable before powering off the uBITx.

Introduction / Newbie Questions

 

¿ªÔÆÌåÓý

I just received my uBITX 6 Saturday. My interest is in updating the Arduino firmware. I¡¯ve been doing Arduino programming since this summer (2020). ?I¡¯ve been successful in compiling and uploading the latest firmware downloaded from GitHub.

?

I¡¯ve started some review of the software and hardware and have some questions.? Rather than filling up everybody¡¯s inbox, I¡¯ll put them all in one email.

?

Firmware version

The screen on my radio displays v6.1 and I can see where that is hardcoded into the source code, but the Readme file in the source package that I downloaded from Github says version 6.3.1. What¡¯s the difference?

?

Connectors

I like the fact that my radio came with additional connectors for my own hardware mods, but I¡¯d like to buy some more. What are these connectors called, and where can I get some? I¡¯ve looked through a lot of connectors on Amazon, but I can¡¯t find any the look right.

?

While the cable to connect the rotary encoder has 8 pins to connect to the raduino, only the 4 going to the rotary encoder have wires, the rest were cut off at the connector. I think it would have been better if they could have left cables that I could have connected to for h/w modifications. I know I could rewire the connector using the spare cable provided, but I was planning on connecting that to the Audio1 header. Has anyone had any luck replacing the cut off cables on this connector?

?

Display

I located a display on Amazon ()

?

that appears to be very similar. However, the docs say that it only runs on 3.3V, not 5V and that level shifters are required. I don¡¯t see those on the schematic. Is this display being run at 5v?

?

I see that there is a SD card slot on the display board in the uBITx. Can that be used?


Rotary Encoder

Is this a mechanical encoder? I found some similar looking ones on Amazon, but these have click stops. Where can I get an encoder like the one in the uBITx that has no click?

?

Digital Interface

It looks audio input and output are available on the Audio1 header, but how do control PTT. I guess I could connect to the PTT input on the MIC jack, but is there an internal connection? I¡¯m not concerned about muting the MIC input, I¡¯ll just leave it unplugged. It looks like there is a PTT input at pin 4 on the control connector to the raduino, but as I mentioned, that cable has been cut off. Is there a reason I shouldn¡¯t be using that?

?

CAT Interface

I used hamlib with the FT847 settings at 38400. The frequency display on FLDigi is changing as I change frequency on the uBITx, but FLDigi frequency display is nowhere near the dial frequency of the uBITx.

?

Keying line ?for amp

I see a couple of topics on the forum on there. Is there a consensus on the best way to key an external amp?

?

That¡¯s it for now. Thanks and 73,

Mark, N8ME

An English site of a French HAM, with interesting information about Ubitx.

 

Hello,
See his site (In english), a summary of modifications to do on the Ubitx.

Please let me know what the name of the dial frequency spreadsheet is. I haven't been able to find it in the files section and it sounds as if it is just what I need.?

Thanks - Bob, W3ARA
Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6

 

This'll help with the BFO adjustment, JT:



You might have to work back and forth a couple of times between VFO and BFO.

To check your frequency, dial up one of the WWV time signals.? 5000 KHz and down is better at night.? You should be able to get 10 MHz during the day, and maybe even 15 MHz.? There's an audio tone most minutes.? Load up WSJT-X and use the waterfall to read the frequency.? Using the microphone on a laptop will do the job - no need to connect wires from computer to radio.? The all knowing Wiki has the table of audio freq table:


?Enjoy the tuning!

Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6

 

I guess my 200Khz off frequency may be a bit misleading, Its on receive, and I compared it to my regular HF station on receive listening to a net that runs here every day. I haven't tried TX yet.

This is where I get lost as suggestions for numbers to use etc..., ?I believe refer to a spreadsheet. I had not heard of this till I posted here. Ive looked in the files and think I have found that spreadsheet.?

Thanks Bob and all for the suggestions as every little bit helps.
I warned everyone that these were Ubitx noob questions....lol
Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6

 

JT, my first question is: What did you use to know you are 200 Hz off frequency?
If it's someone's Flex radio, that radio can help you by moving the frequency a slight amount and rechecking and seeing the new number. From this, you can "guestimate" what number to use and recheck until satisfied it's on frequency.

There is a spreadsheet in the files section of BITX20 groups.io.? You put in the dial frequency, the actual frequency, and the current calibration setting.? It then gives back the correct calibration setting to enter.? There is a page where you can read and change that calibration value.

2. Ive read that I can use the microphone as a Morse code key. I could use the solid carrier for tuning to frequency. Does the mic stay in the mic plug or get moved to the CW plug.
You plug it into the normal mic port.? The change is in one of the settings where you set up the radio for CW mode.

3. The sound from the internal speaker is as expected, however even with my bass enhanced headphones it is very very well entrenched in a treble sound to a level that its hard to listen to. I don't expect home theatre sound...lol But is there a way to smooth out this treble based harshness.
This is a BFO adjustment.? I use this video even though it is not for either of my boards (v4 and v5).?


The process is the same, it is just how you adjust the values that is different.? I believe that Reed's is very close to the same way as the stock v6.

4. Last point is that its a detailed search on the net to get instructions for this albeit a simple radio. Where are the instructions for this located? The only calibration method I found was a video and it wasn¡¯t the Reeds mod.

There are instructions in the files section of this site.? Do a search for "manual" or "instruction".

I would suggest that you research the above while you wait for another person with a better experience to respond.

Re: Frequency calibration, Tuning Question, Sound very tinny questions Ubitx V6

 

JT, to use the mike as a CW key, you have to be in CW mode and maybe select straight key from the CW menu (Press and? hold tune knob for about 15 seconds). Watch for others' comments on this.
