[Elecraft] K2 low ouput in digital modes

[raimon]

Dear Don

Many thanks for your quick answer to my question.

You are right, it was my fault: I compared the RTTY filter set to SSBCr 
1-1 with the SSB filter set to SSBC 2-1 (the setting that I use for 
voice operation) I forgot to modify this setting when comparing output 
power.

Now, with the same SSBC settings in both modes (1-1) there are not 
differences in output power.

On the other hand, increasing the audio output of the soundcard and 
transmitting in the center of the bandpass  I get 70-80 watts in 10 
meters and RTTY.

So, all is all right.

Many thanks again for your help!

Raimon,

If you have the RTTY FL1 filter set to OP1 and the BFO frequencies set 
the same as for SSB, there should be no difference.
EXCEPT
The RTTY filter set has an independent SSBCr setting in the menu, and it 
should always be set to 1-1 for data modes.
If you have the SSB menu SSBC set to add compression to the signal, that 
would explain the difference, but if so, it is causing distortion on 
your data signal.

Yes, you will have to increase the audio gain on the higher bands where 
the transmit gain is lower.

Re-check the filter settings.  If the FL1 filter is set to OP1 and the 
BFOs are set the same as for SSB, then there should be no difference if 
you set the SSBC menu parameter to 1-1.
