[RTTY] RTTY - Slow computer problems

[Robert Chudek - K0RC]

Hello Dick...

This sounds like something that is grabbing the CPU attention which in 
turn suspends your MMTTY decoding. Things that will cause this include 
virus software, indexing software, and potentially any other software 
that may be running at the same time.

One method to see what software might be the culprit is to launch the 
*Windows Task Manger* (Ctrl+Alt+Del). Select the second tab 
(*Processes*). At the top of that screen you can click the *CPU *column 
title *TWICE*. This will sort the list according to how much CPU 
resources are being used, with the highest usage at the top.

Keep the top of this window in view while you are operating. When your 
system pauses, check this list to see what "*Image Name*" and how much 
CPU is being consumed. It's normal to see the numbers in the list move 
around, even when the computer is idle. But if something grabs 90+ 
percent of your CPU and holds it in synch with your delayed RTTY 
decoding, post the name of that process here. This will provide a clue 
to investigate further.

It's normal to see MMTTY using 40% and N1MM using 15% of the CPU while 
operating. Those CPU numbers will jump around, but the total of the two 
normally remains less than 80% CPU utilization. These numbers come from 
my Dell  2-GHz laptop with 1-Gb of RAM running Windows XP sp3.
