Will the ver 6 continue for awhile or will the sBitx replace it soon? Does the sBitx have filtering for BC band interference? Thanks?

Functionally, v1.2 is the current peak for this software. It is restricted to Nano processors and is shoehorned into the memory of the nano. Certainly it has better “eye candy” over the more recent software. I will leave it to others to compare functionality as I am not familiar with the latest software.?

I am working on a “2.0” version of kd8cec software that runs on non nano processors. (See GitHub link in my sig below). ?The hope is that these faster processors with more memory will provide greater headroom for this software. However, the first phase is just to preserve existing functionality on these newer platforms.?

I have successfully installed version 0.2 of his excellent firmware on my uBitX V6.1



This is a vast improvement over the original for CW operation and the CAT control works well with FLRIG.

I am studying the upgrade to the Nextion TFT display.? It will require some modifications and I am studying the documentation.?

Is uBITX_CEC_V1.200.zip\uBITXV5 the latest firmware for Nextion support?? I ask because it dates back to 2019.

What additional features will the Nexion upgrade provide? over the present TFT display??

I'm satisfied with N8ME's code and want to determine of it is worth the effort.

Thanks in Advance,

As mentioned on ubitx.net, there are different versions of the Adafruit MAX9814 for sale on eBay and elsewhere. Does anyone know which version is best to be used for AGC on a v6 uBitx?

? ?...doug, K6DRK

Just a heads up to any that may have missed it or new to the group.

?

The AGC files including gerbers are in the Files section under kit-projects.

?

The AGC on the site at this time is not for the uBitx and only for the Bitx40.

I would like to buy the same if it is still available.

Is the AGC board still available?

I didn’t save a copy of the calibration unfortunately. I didn’t know that was possible. I’ll look into the memory manager.?

The am station was not coming through before I tried tuning to it. I’ll have to try another calibration. I do have a nano vna so I’ll give that a shot.?

Spencer,

There are two possibilities that I can think of:
1 - The AM station is close to your QTH and overloading the first mixer.? That would mean a BCI filter is needed.
2 - The other possibility is that you tuned the v6 to receive the BC signal and not the standard HF band signals when you did the calibration.? That would require a recalibration using another standard.? I use WWV, though dealing with the tones is an issue.? The other calibration option would be to use a signal generator as the AM source.? By chance, do you have a NanoVNA or TinySA?? Either can be used as a signal generator if you do not have one.

The most likely cause is the first.
By chance, did you save the calibration file using the Memory Manager from KD8CEC?? If so, I would load that into the Nano with the KD8CEC software and see if that solves the problem.

Hi Evan
The encoder is plugged into the back of the raduino board. I can change the frequency in the screen, and I am able to pick up strong signals while tuning (ie: 40m Ft8) but even while I hear the Ft8 tones the am station is still coming through as well.?

if I have time in the next few days I’ll try and record a video of what it’s doing. This thing is weird.?

Nice work, Mark!

Hi Spencer,

If I have read your post correctly, you can not change the frequency with either of the two Nano MPCs.? I do not see how that can happen unless you plugged the tuning encoder into the mainboard instead of the Raduino board.? Have you tried to set the frequency with the touch display?

Doug,

If you find a link that you believe pertinent to the V6 I would ask on the group page or contact the author directly before posting the link to the Wiki or your web page.

Support@...

I tested the voltages at q7 and they are very similar to the readings on the chart you provided the link to.? I did some more testing, this time with a Bird 43 meter with peak kit.? Turns out that it does transmit when in ssb mode, my other meter doesn't read peak even though it has a peak switch on the front.....
The radio was still a bit off, so I took a shot at calibrating the unit.? Following the instructions on the ubitx site I tried tuning it to a strong am station and calibrating the vfo. (the station os 820khz).? After trying the best I could to zero beat the station, I tuned to 7.074 to see if I was on frequency as a test. I'm not sure how, but this thing has still managed to stay tuned to the am station. I have tried to power cycle it, unplugged power, even reinstalled the old display and arduino.
I'm not even sure where to go with this thing now, nothing it is doing is making any sense.?

Thanks

Hi Thomas,

Does this include those of us that have not received our complete kit yet?

I am looking forward to this upgrade kit. Thank you, Ashhar.

Hi, Mike. I'd be happy to move the content to the wiki. My concern, and the reason I started the page, is that it's hard to know what works with the v6 kit. I've already purchased two mod kits only to discover they're not quite right, Can you suggest a way to organize the info that is (a) v6-compatible/specific, and (b) still within the structure of the wiki?

? ?...doug, K6DRK

Farhan??? thanks for the super Christmas present.? now I can take that box off the shelf !!!?? and melt solder!!!!!!


did you ever get a chance to work on your tentec argonaut, putting in the VFO PTO rebuild kit I gave you at Dayton ??????


stay well my friend.
