Hi Paul,

guess my preferred method is a linear S= SB exciter which can do all sorts of modes, including specialties like chir= ped Hell and picture transmissions, or 1-dB stepped power tests. On the oth= er hand with one sitting here this is easily said ;-)

Stefan and To= m have successfully employed a Raspberry Pi, which can produce modulated RF= directly on one of it's digital output pins. This has been used for W= SPR but I guess it could also make DFCW.

Best 73,
Markus (DF6NM)&= nbsp;
