Tyson,
Thank you for sharing this info; I will follow your method; The idea to include a separate POT was because the POT come with the kit, and I didn't know about a different option to replace it. I will start the installation today. again thank you.

Right, I am exploring that option as well, after setting up the filter inside the uBITX, that will be the next step, thank you

Re: Folder Name fFor Re: Reed's sketches #ubitxv6 #arduino #nano

Jack, W8TEE
 

The folder name MUST match the primary INO file name (the one with setup() and loop() in it). With Reed's code, the folder must be ubitxv6 and all 60+ project files go under that folder. Load the IDE, go to that folder, open it, and double-click ubitxv6.ino and it will load everything. For example:

    C:\unbitv6\bands.cpp
                     bands.h
                     button.cpp
                     // and so on...
                     ubitxv6.ino
                     // and so on...

There are two folders in the directory, too (PDQ_MinLib, toneAC2).

Once you have the Arduino IDE open, under the "Tools" menu (which you should be able to access via keyboard by pressing Alt momentarily, and then navigating via the arrow keys) you'll need to set the "Board" to "Arduino Nano", the "Port" to whichever USB serial port is assigned by the computer (might be the only option, if you don't have anything else connected), and the "Processor" to "ATMega328p (Old Bootloader)".

Re: How install Sotabeams Variable Bandwidth Filter inside uBITX V. 5 #filters #v5 #bitx20

R. Tyson
 

Hi Al,

I did this fairly recently and must say the Sota Beams filter is very good. It turns the uBitX into a very good cw rig.

I have included a drawing I did for someone else - J1 is the yellow wire coming from the board to the input of the volume control pot. J2 is the output (if I remember correctly) back to the board and then to the earphone socket.

My wiring allows the filter to be switched out completely, or just the wide cw filter to be switched in. Switching in the narrowest CW filter is done by means of a separate switch which (if I remember correctly) takes a separate lead from the filter board itself and puts it to ground.....   I haven't shown the separate switch as its very simple and there is no need to include it on the drawing. The setup works very well. I don't know why you would want a separate pot. for the filter as my method allows the volume control to work as per normal.

There is a ground connection to the volume control pot. but for simplicity it isn't shown.

My uBitX is a version 5 type and I haven't looked at the latest version. The diagram should give you an idea though.

These work well bit are a bit expensive.  There is a guy on github that took some code i wrote for the same chip and added a very nice graphic interface with a small display to make it Look and operate just like the elecraft K3.

Re: My V6 UI has suddenly started beeping with each button press.

Dale Parfitt
 

Hi Reed,

I am with you. I   have an Elecraft K3 and have had the KX-3. Excellent rigs but one cannot do any mods or customization. The Bitx is the ideal platform for this. I have already designed and added a 160M LPF, added AGC, done the hiss mod- (photo attached), and adding a tiny active SMD CW filter- bandwidth of MY choosing. Also a custom  cabinet, set out for the way I operate, internal batteries and will be adding a 6 and 2M transverter down the road. There are plenty of turnkey transceivers out there for those that don’t wish to design and experiment.

Hi Jeff,

I'd recommend trying to keep each thread on topic. It makes it easier to find and make sense of the conversations on here when looking back at older conversations. That said, I'll still answer your questions here.

You can see some of the features listed in the readme file in the project: https://github.com/reedbn/ubitxv6/blob/master/README.md
I made a lot of changes on the back end, but tried to keep the stock look.

If you search this group, you'll find people reporting 12m use. There aren't any software limits to prevent it, and even if there were, you could change the code to allow it. https://groups.io/g/BITX20/search?q=12m
I believe that 160m is also possible, with some additional filters. Again, search this group and you'll find threads talking about it.

I personally got the uBiTX because it's designed for tinkering, but has the base tech in place. I read up on it on variety of sites, including this group, before purchasing, and was fully aware that there would be some elbow grease required. It was actually easier than I expected, since I researched v5 but got a v6. But I've never seen anybody on here say that this radio is for people who want a radio that "just works" for SOTA. If that's what you're after, you might want to consider the big 3, or something that's purchased as a complete product, not a kit, like the minion sdr.

Another potential problem is the CH340 device driver. If the compile goes okay, but the upload fails, it could be that you don't have the CH340 device driver installed. Just search "CH340 device driver download", download it, and run the installer. You should close and re-open the IDE after the CH340 installer finishes.

Here I placed a nescaf inside my v5. The audio chain needs to end with a strong audio amp. Insure that a dc blocking cap is between biased stages. Does that audio filter include an audio amplifier at the end? I spliced mine between the wires feeding the speaker and headphone jack. Draw a picture to see how everything needs to fit.

Also, my idea is to use a separate POT to control the filter.

Re: My V6 UI has suddenly started beeping with each button press.

Jeff Debes
 

Thanks again Reed for hanging with me and my sometimes (I know) annoying comments and questions.

I tried the BFO alignment/set with my home laptop and it seems to work, but I have a few comments on the HF Sigs instructions on the tuning aid:
Maybe the tuning aid should instruct  whether to use just ‘noise’  vs a signal and/ or if one should disconnect the antenna etc. Maybe a signal is good to view on it?

I  dislike the need to have to twitch the tuning knob in order to enact the switch between LSB and USB. But at least it works that way now.   BTW In the tuning aid instructions,  the word that is intended to be “approximately”  is misspelled. Should be corrected.

I think you said you have a software release that fixes that and the touch response button highlighting and visual indication of touched soft button? What else?
And:
Has anyone created a  12 meters version?
What about 160 meters? ( I take it hardware design might not work for 160) .

Segway, back to other questions and comments made: 
I like to do some SOTA ( Summits On The Air )climbing mountains, making contacts, getting points for peaks climbed and contacts made. I get lots of exercise when i do these treks. .....  but this  is one reason for wanting a minimal tinkering, off-the-shelf QRP rig that could be used portably. My  decreased motivation to dive into many new things, to understand the guts of the radio architecture, or fixes , etc is driven by my own view and interests in ham radio as a hobby.
And there are many others like-minded out there.
 So in this regard, it might be good for the support group and for HF Signals to tailor expectations to meet the need to help out operators who have similar interests. 
How much more might a fully assembled , tuned and ready to operate V6 go for ?
$250, $300 , $350  Many might buy it.
Thoughts?

Folder Name fFor Re: Reed's sketches #ubitxv6 #arduino #nano

Hello: Reed 

I am very close in  beginning the update of my UBitX V6 with your V6 update. 

First: it is nice to notice a V6 user who accidentally discovered the CW read of the display for person's  who are Blind. As a person who is blind it made me smile!

Second: I have downloaded and installed the Arduino program. Also, I have downloaded your V6 zip file. Both files were downloaded via Microsoft Edge. They are both in my Windows 10 download folder. Which folder does the zip file contents go in to?  

Third: My NV Access screen reading program has problems in reading  the Arduino screens. Can I make setting changes and update my UBitX  via Arduino hot keys? If so, which order  of the Arduino hot keys are to be used?  By the way, could a scrip be created for Arduino program in updating the UBitX V6?

Appreciate all the help.
