Subject: [RTTY] AA6YQ Question?
When we were setting up the club station for WPX, our PC was running
sooooooooooo slow.
I am not sure what the processor is, but typically the speed is fine.
We loaded the AA6YQ profile on our MMTTY clone receive copy.
Eventually we watched the processor usage and found that it was running at
100% usage with that profile turned on.
We turned it off and the processor usage returned to about 20%.
I do not experience this issue on my contest PC which is very old and only
has 356K of memory.
We tried it on a second computer at the club and all was fine.
Any ideas what may be happening?
>>>All of the MMTTY profiles I've developed use sharp filters, which require
more computation to implement than do broad filters. Recent dual-core
microprocessors with access to reasonable amounts of RAM should have no
problem with this. The microprocessor in my PC is a 2-year-old Intel core
duo 6600 clocked at 2.4 Ghz with 3.5 GB of RAM; on this system, MMTTY
configured with the AA6YQ-FIR-512 profile shows CPU consumption around 5%,
which is barely noticeable.

Dave, AA6YQ
