Power output is low, although output power is ok using quisk

[Jose Berrios]

I noticed an odd SparkSDR behavior recently. The output power is low while the SWR is normal.

I previously increased power when increasing drive power, but it doesn't change the power output.

I am fine with using Quisk. I can increase or decrease the power output. Also, I must enable PA before the SWR shows correctly. The SWR is confirmed as correct using both a direct inline reading and the SWR reading from Quisk. 

The PA current stays low with SparkSDR but is higher when using Quisk.

I would appreciate any suggestions you can give me.

I'm running the Linux version of SparkSDR on a Ubuntu 24.04 PC.

Hi Jose,

not sure what is happening here, the things that can affect power are drive, pa enabled and filter settings and in some modes the mic gain/compression.  A screen shot might give a clue.
