My installation of version 2.1.5 went very smoothly, and it's working
great, however, I have run into one anomaly:
Using a fresh database, while operating in FM mode, when the squelch
slider is moved above the threshold point, my CPU utilization rises from
20% to 70%. At that level PowerSDR becomes very sluggish. Dropping the
squelch level down below the threshold returns the CPU utilization back
to its normal 20% level. Switching to any other mode also drops the CPU
utilization back down to around 20%. Engaging TX also drops the CPU
utilization to roughly 20%. Engaging the squelch in any other mode does
not cause the issue. All the settings in the database are at the
default, except for ANT which is switched to ANT3 for my 6 meter antenna.
Any thoughts?
On my system the CPU utilization varies from one second to the next
wherever the squelch slider is set. With the audio unsquelched it varied
from 3.1% to 13.1%; with it squelched it varied from 9.7% to 19.6%. So,
yes, a slight increase, but nothing like the CPU load you reported.
