Have to adjust master calibration on power up - does not save

 

I just wanted to ask this question.? I have assembled my v.3 ubitx, using it for several months, works great and no complaints from my contacts.? It is just a little annoying to set the master calibration every time I power up the set.? Now, I am using the original factory software, since all I want is just a basic SSB radio. If that's the way it is, so be it. Since there hasn't been any other complaints regarding this, I am assuming I am overlooking something. Best regards and please advise.

I am thinking that you have to press the microphone button to save the setting after you do the calibration.

I usually save it that way.? I have also replaced the Arduino PCB thinking that was the problem.

I¡¯m not exactly familiar with this master calibration. ? I found a way to simply measure the offset of the 25 MHz Crystal by having the system send a 25 MHz signal and measure it with accurate ?receiver. And then I simply edited the code to make it be the correct frequency. ?

Typically my crystals ended up three or 4 kHz off at 25 MHz ? Once the code reflected their actual frequency, life was good

When the set is first powered on, there is a tinny, high frequency audio.? When you enter the setup mode and enter calibration, pressing the menu button, the audio is normal tone. Then I adjust the calibration level and set it, then exit, all is well.? Until I turn it off. I have tried other software with no luck. So I re-loaded the original factory software. I thought with all the issues you have seen with the various ubitx versions that you people may have come across it. Thanks anyway.

Hi Bob,

I do not see the part where you save the setting after you have set it. Press the push to talk button to save it while you are still in the calibration mode. Otherwise it does exactly as you describe and will be back to the original next time you turn it on.

Before you leave the calibration and after you have it where you want it, press push to talk. Not your CW key. Not later after you have left the calibration mode. Before you leave calibration.

Sorry Bill.? I didn't mention that I do set it with the PTT switch, then exit the setup mode.? This set has exhibited this symptom since day 1.? I thought changing out the Arduino would have helped.? Before that I was adding caps to the reset.? Thanks anyway.

I think that your uBitx thinks you are not calibrated. There is a function of the software which is entered when you have the encoder switch depressed during power up.
Did you install capacitors on your encoder lines for de-bouncing? If yes thry to remove the one on the switch line and see if it helps.

Ion,
Hey guys, I am an idiot.? My BFO freq. was way off.? The only way I found out was running Ubitx manager to see the saved setting. There was incorrect data entered at one time or another.? Anyway, I got in some good practice with my small torch removing and installing that Arduino. I have now have it set to 119965 and waiting for band conditions to improve.? I tried listening in on another radio but the distance between the 2 is too short. Thanks for all your help. ?
