Hi,
I'm running SDR# version 1732 with an  Airspy HF+ Discovery.
To check the frequency accuracy of the Airspy  I tuned to 9,996.000 MHz LSB (Russian Time TX).
I can click USB , DSB, CW and RAW modes OK, but when I click the AM mode  the frequency sets to 9,995.000 MHz  and when I click the NFM or WFM modes the frequency sets to 10,000.000MHz.
Once it is set to 10,000.000 MHz I can click all modes setting remains 10,000.000 MHz.
When I set To 9.996.000 in one of the FM modes, I can set all modes without frequency change except The AM mode changes to 9.995.000 MHz and the other FM mode to 10.000.000 MHz

That's the expected behavior. The frequency is aligned to the step size of the selected mode.
If you don't want it, you can disable it in the screen. The option is "Snap to grid".

Prog,

Thanks for the  reply, I didn't know that, will reset it.
