obviously we don't understand each other! I can not do the calibration I am shifted in frequency, I do not understand what xh please excuse me! I don't use the Digu, I have the default parameters
could we connect xon Team Viewer?
do you have Skype?

request: why do you have the SSB taps at 3000?
Regardless if your shifted or not:
If your using 1496.000.000 as your KNOWN GOOD FREQUENCY:
Put the SDR 2 DX in Standard AM mode and place it on 14.996.000 ( I think that is the frequency you said your using as a calibration source)
Now listen to the tone there and using different values in the Calibration (Frequency Correction) box
lets start with this: 0.000130 and press WRITE
Now listen leaving the radio on 14.996.000 in AM mode is the frequency Shift Closer zero beat tone or move further away
Going from what you find above adjust the LAST 3 digits of the correction, if closer try 0.000140 and press write
If it made it worse then try 0.000120 and press Write
again listen and adjust from there until you get it on frequency
Each time you enter a New Number in the frequency correction box you press write and listen to see if it is Closer to 14.996.000 or not and keep adjusting
I do not use TeamViewer nor Skype
It really isn't difficult to adjust it is just time consuming and takes a good
as for why I use 3000 ( the higher the number the tighter the filtering) tighter filtering means less IMd esp. since I like to run wider TX bandwidths on SSB
For digital modes it can be less, but for SSB I want clean signal as I can produce
this also requires a PC that can keep up with task of tighting the filtering as well as it requires more system resources to do so
So leaving radio frequency on 14.996.000 even it that is not on frequency you need to have that value in there so it can write the correction to place the radio on that frequency when you are done
Using AM mode is in most cases easier to hear if you Zero Beat or if your still off frequency as your will hear heterodyning on the signal like in the video I share for you earlier.
Just Rember when you change the correction value you must press WRITE in order to process the change and then listen carefully and adjust again until you reach your goal
when you are done , placing your radio on 14.996.000 will produce the correct frequency going forward and you will be good
