Hi Peter VK3YE

Ill try listen out for you on the Bitx frequency 7177. maybe just maybe we can QSO...

I will explain what I did and it worked for me.
Turn ON the radio with the function (encoder push button) pressed and hold it.
Watch the screen for messages to reset to factory defaults.
Last thing it will ask you is to turn off the radio and back on again (power reset). Do it. Connect your antenna.
You are now at the beginning of the calibration.
Go to settings and enable them (if the message on the screen reads "setup on? press the encoder push switch).
Set the radio on 30m (10.100 MHz) and rotate the encoder until you are on 10.000 MHz
Press the encoder again and now, after "exit menu?" you will have more options in the menu. 
First option in setup menu, after "Exit menu?" is "Set Calibration?". Select that and zero beat the carrier. You have to spend some time there until you hear the voice and the voice should sound decent. When you are happy with the result press PTT and after a second or two do a power reset (Radio off and on again).
Select a band where you have activity and tune to a station that is not very strong.
Enable again Setup menu as above. Enter setup and go to "Set the BFO". Select that option by pressing the encoder push switch.
Your BFO frequency should be around 11.997 MHz. Adjust the BFO to get the natural sound. Press PTT when you are happy with the result and do a last power reset.
Try to find a broadcast SW station (in my case I can hear a broadcast station on 7.210 MHz in the evenings). Check that you cannot hear the carrier and there is no difference in the reception sound if you switch the mode from LSB to USB.
It only took me 10 minutes to have it done and I am happy with the result.
Good luck and 73,

Please state what firmware and version you are using when stating a problem or explaining how something works.

There are numerous versions now in circulation.

Ion,

Thank you for your help.I will give it a try tomorrow and let you know how it goes.

I was not able to zero beat the carrier from WWV on 10MHz (there was no null or center).

I also may have deleted the default values when using the KD8CEC Memory Manager. What default values do you use?

One guy used a Master Cal of 143000 and USB Cal of 11996200 which worked fairly well except for the 270 Hz error which I couldn't correct.

Will let you know tomorrow....

Need modified BitX40 Sketch

AA9GG
 

Does anyone have a copy of a BitX40 sketch that has the rotary encoder mod?  I was going to just start with Allard's latest (v1.28?) and go from there, but I'm not sure what all has to be removed/modified.  I know how the encoder works and have the interrupt routines to read and set the freq ready to cut and paste, but what about the other routines like in the calibration routine.  If someone already has the code modified and working no sense in re-inventing the wheel...

thanks de AA9GG

Re: Receive pitch shifts when confirming.... #arduino #ubitx #ubitx-help

 

Correct, only PTT sets it or else it reverts back to old value.

It says PTT to confirm.

I think the number is changing but not the pitch.

To hear much of a zero-beat, the BFO should be set within the passband of the 12mhz filter as per post 54501.
I have no idea how the various firmware releases out there are doing in that regard.

Hi Michael,
Here is my calibration saved with the help of uBitX manager.

You can try loading it.
I do not have a factory settings files as I replaced my Nano.
You can get the factory values by uploading first Farhan's firmware 4.3.
Hope this helps.

connections to copper islands. pads or areas where soldering is required that are not simple traces should be defined as a thermal (relief) pad.

Re: [VK3 Event] Bring your Bitx/uBitx - Melbourne QRP by the Bay 28 July

 

Hi Peter and all,

I hope somebody videos it for the rest of the world. I would love to see what everybody did with their uBitx/Bitx. I will be receiving my second uBitx Thursday to go along with my Bitx60 and my Bitx40 using the ozqrp VFO.

The Baofeng spk/mics sound muffled on the Baofeng radio. They have plenty of gain for the Baofeng radio but are very weak on the uBitx. The -24dB element brought the level up nicely. Order a few to play with, you won't be disappointed.

Re: Mike element

Stuff out there sold as a Baofeng mike can vary.
Perhaps Baofeng has several suppliers, I'd guess some are clones.

I bought a couple off ebay.
Element was fine, but plastic shell needed a hole drilled into it over the element.
No hole for sound to get in would definitely make it sound muffled.

Had no use for the speaker or transmit light, and didn't like the tug of the coiled cable.
So replaced the cable, put a 3.5mm stereo jack on the end, wired it up
to just have a mike element and PTT switch.  

Mike element and PPT switch seem fine.

Vias are used to get from one side to another or as a top ground to bottom.
They are just plated through and often solder masked.

Like leaded component holes they are just plated through and can be defective or 
marginal.  When a soldered lead is there it tends to mask that but a via being 
unfilled by solder can fail.  

Its east to test for such a failure, ohm from point A to point B and if the resistance
is not very small (miilliohms typically) it is suspicious. 

Generally the via is sized to have at least the current carrying ability as the trace
leading to it or more.  When the work I've done on the my board I've had traces
vaporize but the vias were intact.

I chalk this one up to one of those odd failures that can happen in large board runs.
Unless its a more than .5% event its likely anomaly.
