[RTTY] RTTY - Slow computer problems

[Larry Gauthier (K8UT)]

Bob's got some good ideas... plus try turning stuff off and see what 
changes:

- close all other applications - especially things like email, IM, Skype
- run MMTTY in standalone mode (without N1MM Logger)
- temporarily disable your antivirus , disk indexing, firewall software
- unplug your Internet connection

>From your description, it sounds like whatever is doing this has been 
following you around for many computers. Thus, my guess its that the culprit 
is some program that you intentionally installed - not realizing that the 
program "phones home" on a regular basis and consumes the CPU's cycles when 
doing so. Good luck finding it!

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.
