[Elecraft] K3S drops 10db with Digital Modes

[Karel Cornelis]

Hi,


Somebody mentioned me that my signals goes up and down about 10db when I send out digital mode via pc. (psk, simpsk). ( checked it myself via  a websdr station close to my QTH, so no propagation )

I already switched off TX ALC but there is no difference. Compressor is off, tried low and high power, low and high output of pc sound does not change a thing, TX EQ is not used, ...

When I do the same with my Flex, with the same pc and the same programs I don't have this up and down issue.

I checked the USB Audio Codec sound card settings, but I don't see any settings in there that could cause this issue.

Has anybody got an idea about this? It's not a real issue to work digital modes, but I'm curious to know of what is causing this.


Tnx 73 Karel
