Re: zBitx +-2 MHz transmit spurs? --> SHOWSTOPPER for transmitting


 

If the problem is related to the change of power supply voltage due to periodically changing current consumption, the problem may persist with battery supply.
They have non-zero internal resistance.

I tested my unit with two different sets of batteries, and saw the +-2 MHz spurs. So it's not external SMPS noise.

The spurs were there when trying to FT8, CW, and 2Tone modes, They only vanished when trying SSB with no mic, thus 0 output.
