The 2N2219 is physically bigger same Die inside so yes, you can use either.
I specified the smaller can 2n2222A as most would be easily bothered by
large transistor and small space.  Neither case heat is NOT and issue.

Heat for that sot is not a big issue, space is.  So if you use 2219s insert them
(observe pin out carefully) from the underside of the board.  That will allow
more room.

As I recall, discussions a year or two ago, it was a good idea but you also need to change the biased point to reach maximum gain at the frequencies of interest. That requires a bit of an understanding of common amateur amplifier biased, but Alyson had given lots of information on how to do it, you might search for her very very detailed posts from back.

If you set up the AVR tool chain, you can put the files anywhere. But the Arduino IDE imposes the "folder name = ino name", and most people use it, not a terminal. The Arduino IDE doesn't care where the folder is, but it does care that the names match.

Arduino IDE okay:
C:/Foo/Foo.ino
C:/Users/Reed/Desktop/Bar/Bar.ino

Arduino IDE rejection:
C:/Bar/Foo.ino
C:/Users/Reed/Desktop/Foo/Bar.ino

Files are in the same structural location, but the IDE will reject them because of the name mis match.

I just set your message preference to FULL DIGEST which should

I also sent you a message similar to this from my ID on the BITX20

Hi Dave,

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)". With those settings in place, you should be able to press Ctrl+U to compile, verify, and upload/program.

Seems that just like traditional C-compilers you can provide full path to

Re: New V6 CW tone frequency

roebi@...
 

Finally I found the problem.

After calibrating, the SSB reception was improved, but for CW the filter was still too high. Then I realized, that there is a 2nd bfo calibration for CW in the CEC firmware, and the value was 0. After I copied the bfo calibration to the cw bfo calibration, I was able to get the CW tone to where it should be. Finally I increased the value, to make the filter a little better for CW. 
Still the filter has less attenuation on frequencies higher than 1kHz, so probably I will add one of the CW filter mods.

Thanks, Robert


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

Reed N
 

The folder location isn't important. Can go on your desktop, or documents, or root directory like Jack's example. As long as the folder containing the code is named "ubitxv6" it should be okay.

Sorry to hear that the Arduino IDE isn't very accessible. I hope you can figure something out soon.

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.

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

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).

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.
