I too have called CQ a number of times, no response.

Oh Well, maybe need to try later.? 40 meters seems better at night.

I agree.?? I picked 7pm CDT because it worked for me.? Apparently the ionosphere doesn't care about my schedule.

I have been on since 6:10 and have heard nothing.? Do not have PSK31 setup, so did not try that.

Re: uBITX V6 weird modulation

 

I would agree.? Also, verify if you have that pattern when connected to a dummy load.? The uBITX seems to be susceptible to RF feedback.? .01 uF caps to bypass and Ferrites on the cord.

Re: uBITX V6 weird modulation

 

So i was fiddling with the calibration, and using the sdr to see my changes, when I noticed how I held my mic cord changed what was on the screen, sometimes nothing, sometimes strong, sometimes strong without saying anything, sometimes even the tx would kick on and off...
So I'm thinking my issue is the mic cord itself.
Re: Wed 7/29 BITX QSO night 7pm Central (US) on 7.277, or psk31 on 7071.5

 

I like the visual touch...hahaha.
Re: Wed 7/29 BITX QSO night 7pm Central (US) on 7.277, PSK31 digital on 7070+1500

 

I'll be on up in Barrie Ontario as well using a BITX40 for starters. On 7.277 LSB now at 2311 zulu.
Re: Wed 7/29 BITX QSO night 7pm Central (US) on 7.277, PSK31 digital on 7070+1500

 

I'm starting early just for fun. In Northern VA.

If I don't hear anyone, I will try simple digital PSK31 on 7070 + 1500.

Re: BITX40 Pop Fix

 

OK, glad to hear you got it working Ted!

Now you can start adding some of the minor mods in order to enjoy the full capabilities of the software.
The most important one that I'd recommend you to start with is adding the function button.
See for details.

Happy BitX-ing!

Also say VFO is not calibrated.
Still have more to do and learn.
Pop is still there on PTT but doesn't seem as bad on power up.

Another question:
If I do just a "Reply" and not a "Reply all" does the msg still go to the group?

You can tell whether the upgrade was successful by looking at the software version number that is briefly shown on the LCD after power on.

Eureka!!!!

?

I had never tried the ¡°Old Bootloader¡± version of the ATMega328 and now with all the other things are setup properly it up loaded with no errors.

Guess that means that the software has been updated to the latest rev. I understand that it has functionality that I won¡¯t be able to use on this oddball version of the BITX40. Hopefully though this will improve the pop noise when switching from TX to Rx and Vicky verky as well as maybe other things.

As this is an abandoned kit from another Ham and a very basic TRX, as well signal band single mode, I don¡¯t want to put too much into it.

May do some of the component mods for other fixes.

I¡¯ll put the thing back together now and see what happens.

Thanks for all of your time and help.

I¡¯ll post the results.

73 and stay safe guys.

Okay Comport set as you suggested. For some reason ¡°Com&LPT¡± did not appear on Device Manager until I plugged in My Navigator and then the Nano. Something I set when setting the Navigator up, Anyway now have Com10 assigned.

Tried the upload again with same results ¡°sync error¡±

¡°AVRDUDE;STK500_GETSYNC()? NOT IN SYNC¡±

I will next check the cable with an ohm meter just to rule it out as a charge cable.

Maybe it just won¡¯t handle data freq.???

More later

Yes using Windows 10. Looks like I messed up the Comport setup but got the rest okay.

Now getting a sync error when uploading so will go back and redo the Comport as you suggest.

Ted,
I assume that you are using Windows as your OS.? If so, then I would suggest that you open the Device Manager through right-clicking on the Windows icon and selecting Device Manager. Open the Ports (COM & LP) and then connect your Nano.? The one that is added is the correct comm port.? (I did not have the Nano connected when I took the screenshot).



Also will need to set up the board:


And the Processor:


That should get you connected to the Nano.?

Re: Nano

 

Ted,
I did get the picture that time.? From it I would surmise 2 things:
1 - That you do have an HF Signals Raduino with a Nano Clone.
2 - That the Nano is soldered in on the opposite side of the Raduino board from the uBITX versions (the Nano is between the Raduino board and the Display).

Attached are pictures of the Raduino shipped with the uBITX rigs:

Note: I did add the heatsink on the Raduino Regulator and replaced the Nano with a clone bought through Amazon.? That way I could keep the Nano in the factory original state.

If you ever decide to replace the Nano, I would move it to the other side of the board, unless you are mounting the display with a cable, then it would not matter.? The Nano replacement will be difficult with the two headers to desolder and all the pins to remove.

The settings for the Arduino IDE that we have sent you before should work.? If not, you could try changing the processor to the standard ATMega328P without the Old Bootloader.? Other than that, replacing the Nano is the best option at this time.
