FLDIGI Power output

Jim

I am using my 6600M with a PGXL Amp.

With the amp set at 300 Watts, when I click the tune button on the radio, I get a 285 watt output indication on my power meter. All is well.

HOWEVER

With the exact same settings, if I transmit with FLDIGI, i can only get 50 or 60 watts output.

Other than that, FLDIGI works fine. Any ideas as to what might be going on would be appreciated.

Hi Jim, check the DAX TX Gain.

Adjust it so that when transmitting in FLDigi, the peak level indicator is somewhere around -5 dB.

Thanks for the reply Len, but not the problem. I have full output from the amp until I fire up FLDIGI, then the output is way low.

Those audio levels that Len pointed out are the first thing to check. If those levels are not what at what Len pointed out, you will not have full RF level output.

It is the audio level in a digital mode that generates the RF.

Let us know how you make out.

My setting are as you indicate.

If the Level meter on the SmartSDR client is near full scale and you are not getting north of 80 watts output, then you'll need to open a support ticket.

The level meter confirms that the correct drive level is making it to the radio.
