Flex 5ka
XP Home SP3/AMD Quad core @ 3.2 ghz / 3gb ram
firmware v. 2.0.2.2
Firewire driver 3.5.2.8028
cpu usage ave. 6% / latency (typical) 20us - no peaks above 100us (very little change from 1.18.5).


Yesterday, I noted the "pop" I am hearing when transitioning from tx to rx on receive. Last evening, I also noticed a short "crack" or "pop" when transitioning from rx to tx on cw. Delay does not seem to matter. the TX/RX pop seemed related to the rx gain, as it was worse with the pre-amp on.

This morning, I was on ssb and noticed the same artifact when transitioning from tx to rx on that mode.

These were not present using PowerSDR 1.18.5 - 1.3.0.8 - 3.5.0.7171

Am I the only person hearing this?
