Ok,  we are making good progress.

I found another issue,  this time with AM/FM,  mostly FM.

AM modulation appears to work,  however the "CW Frequency" should be "Mod Frequency" or "Modulation Frequency". So really just a typographic issue.

FM on the other hand has some serious issues. It would appear the Parameter frequency is being ignored to set the carrier frequency and instead "CW Frequency" is being used to set the Carrier frequency. This is fine except I can't get the modulation frequency to set. Perhaps the "Frequency" and "CW Frequency" fields are flipped around. In any event FM modulation isn't working at all well for me. The DDS functions are getting very close to fully working.

Edit:
I confirmed that the two frequency fields appear flipped,  also entering 10000000 (10Mhz) into the CW Frequency field results in a carrier frequency of 5 Mhz (1/2). I can post more details if needed. The data is being pulled from the wrong field for setting the carrier frequency as well as the modulation frequency, this is only a problem for FM,  AM works well.

Thanks

OK, oddly AM is now suffering the same issues as FM. The Frequency field is being ignored and instead the carrier frequency is set by the CW Frequency. It appears to not have the same issue of being 1/2 the set frequency.

Will this update be for the public?

Has the AM/FM issues with the DDS been looked at yet ?

Thanks

Sir, I have sent the software to your email. Please check.

AM Modulation appears to work correctly. The CW Frequency (carrier wave) places the carrier at the correct frequency, the Frequency sets the modulation frequency and appears correct. Depth works as expected.

For FM modulation nothing appears to work as expected. I'll connect to a spectrum analyzer tomorrow to see what is happening. It's very strange.

Thanks

Hi Amy.
Please help ,e understand this person has some bugs in the DDS you fix it and send this person SW,
I has some bugs which you fixed and you send SW to me
Now when does all the people get the SW which is working and all bug fixed in my opinion my SW has my reported bugs fixed and this person SW has his bugs fix but my SW still contain the Bugs this person has ????????
I am use to that a new version get uploaded for all users not now it seams you get a version with the bugs fixed you reported and the other peoples bug reports are still bugs in my SW
Please help me understand how this is working
