after having paused my activities in hamradio for about 20 years, the ubitx (and especially this group - thank you all!) got me started again. I have now ?built“ a v5, added the Digi-board from?, upgraded to KD8CEC v1.2.?and I ran the first couple of QSOs on FT8 with a misaligned ubitx putting out <1W to my MFJ magnetic loop. Now I think I need to adjust the BFO and perform a calibration:

(Added a screenshot of the JTDX waterfall)?

1. Looking at the audio passband in JTDX, I see it being shifted about 2,5kHz to the right.

2. To get the FT8 signals into the audio passband, ?I needed to set the VFO frequency to about 21.072 MHz

3. Using the bitx manager from KD8CEC, and getting the values from my bitx I see that the I2C value of the SI5351 is set to oxff. After scanning I see it is found at 0x60. VFO B is not what my bitx display shows.

Now for my questions:

For 1&2 I will probably need to adjust the bfo frequency and then use the calibrate menu from CEC. For the BFO frequency I plan to do the first shift of the passband visually in the waterfall, shifting it tot the left untill it won’t move anymore. (I tested changing the bfo which took a LOT of dialing, but after a short while at my desired frequency, the ubitx resets.) Then after saving the bfo frequency, I would look for a signal on a know frequency and use the calibrate menu to dial in. Is this the right procedure and sequence ? Any tips for a frequency/station to use as a reference for calibrating - WWV is probably not usable in Germany, right ?

For 3: Do I just set the 0x60 value manually? Is there anything I need to set before sending the values back to the bitx ? I really want to avoid bricking it now that I got so far. I wonder why the VFOB is not read correctly: 4294967295 but it was set to 14 something. MHz.

Am I on the right track ?

TIA for any help es 73
