Hi Ian:

I think you should consider it, as you have lost all type checking across files by making them all *.ino files. Obviously, this has not been a problem, but might be in the future. Just a suggestion to restore type checking.

Jack.

Thank you for your attention and advice.

I first used Arduino.?So I thought that Arduino was this style.(I did not know.)

I also decided that it would be nice to keep the original name in order to share code in github.?In fact, some or all of my code has been merged into someone else's project.

On the other hand, I received a pullrequest request from someone else and my code was modified.

But now I was wondering if I should keep this style with little or no original source left.

I released it to version 0.35 a few hours ago.It's got more features than I thought with the help of many great people. they has good idea and good suggestion.

I have put all the functions I wanted to put in, except to build in wspr.?So going to release Major in 1.0 soon.

I think this issue should be reconsidered at that point.

Thank you again for your interest.

Hi Ian:

I was wondering if you had plans to convert the support files for your software to *.cpp files from their current *.ino secondary file names (except for ubitx_30.ino)?

Hi,

I know there have been some threads on these topics before, however I'm kinda interested what the current 'state of the art' is, so to speak.

Is there anyone using CAT control on their bitx 40, and how are you doing it? If you are doing digital modes are you using VOX circuit for the PTT, or via another method. Thanks!

Dear All,

Inviting you all to have a look on uBitx Case Home brewed.

Hello Ian,

Thank you very much for the updated version (CEC) 0.34 which is the first that I have uploaded to my newly received UBitx.
It has greatly improved the way my trx operates.
I will be testing it for a while, but generally speaking what I've tested up till now works to my expectations. Congratulations.

One thing that it is not very clear to me is how the split mode works. Is there a link or video for it? It would save me some time from trying to guess how and it would be greatly appreciated. As you may figure out, I also like to chase some DX as a QRP station!

I would like to invest some time to some necessary hardware improvements, number one being adding AGC (testing at first the original schematic), and then adding the s-meter to pin7.
I hope I can also find some time to play with your UBitx Manager.

Taking this opportunity, I would also like to comment that you are doing a very excellent job with your version of firmware for UBitx, and we as users must feel very lucky for that. Please keep the good work.
?
Very sincerely,

That DOES present a problem - LOL.

I found that one does NOT want to power the Nano using the Vin pin if you are using an external supply greater than 12VDC!? The on board LM1117 regulator can't take that with the load of the processor and the I/O on it.? Smoke, fire and flames in the regulator - overvoltaged the processor on the Nano, put more than 5 volts onto the I2C bus so it wiped out the Si5251 Clock chip as well.

I got a real education in replacing the 5351 - LOL.? I have a cheap hot air rework station and it did a nice job removing the dead chip.? I have been playing with the idea of possibly breadboarding a Raduino and have some carrier PC boards for the 5351's.? Still have to solder the chips on the boards though.? I bough a handful of 5351A's from Digi-Key for 91 cents US apiece.?

The way to go was Chip Quik's "Tack" flux - not cheap but 10ml for $20 bucks will last a LOOOONG time.? Dab of it on each pad, position the chip carefully over it's pads and using a needle point tip on my soldering iron, tacked each pin to the board.? I made up a probe for my DVM using a small sewing needle and was able to confirm continuity and no shorts on all the pins.? Programmed a new Nano and replaced the one that burned up (put machined pins and sockets on things this time).? Everything fired up and ran just fine.? Just after I built the test fixture, I read the frequencies of the clocks on my nicely calibrated uBITX and wrote them down.? With the test set, I can go into Factory Alignment mode and with a freq counter attached to the Clock 2 output, I can actually set the frequency accurately and save it.? The BFO can be read on clock 1 and I had those figures too so setting it to the right frequency was a breeze.? After the repair, I re-installed it in the uBITX, tuned to WWV at 5.000.00 MHz (the only one I can hear in Kansas during the daytime) and I was only off by 150 Hz.? Sure saved a lot of time being able to pre-calibrate the clocks outside of the radio!

The only drawback is - the clocks have to be calibrated to the specific radio for accuracy, due to the variations in crystal filters.? You can, however get very close so if I had to replace a Nano for someone, I could pre-calibrate the clocks to close proximity of what they should be and the user could fine tune them in his/her rig.
