Hi Gary,
It's not so much about how good my computer is (they're all good, mine is at the low end of the scale), as it is about what's running in the background that steals focus away for WSJT-X.
Virtually every modern computer that you can buy these days is more than sufficient to the task - as long as its not bogged down in background tasks.  You can easily see the effect of stolen focus by letting 'time.is' run. See how often it hesitates especially on start up, then quickly catches up on its time display.
My example was that, when even a simple low-end lap-top is unburdened of time-stealers, it is more than enough for WSJT-X portable operations (JT65, JT9. and more rarely FT8 in my case - I have no experience with MSK144, but it sounds like my machine won't cut it in that case).
I don't know how to manage the Windows OS to force temporary real-time priority for WSJT-X, other than to temporarily stop antivirus and stop internet access and stop many other background tasks including Windows updates and other file management tasks during WSJT-X operation.

Kindest regards,
Kai, KE4PT

Again, I would urge all of you commenting on how good your computer is with WSJT-X to not just go by how it runs on FT8.  Are you going to stick to FT8 the rest of your life?  The most intensive mode in WSJT-X is NOT FT8.  If you ever get interested in meteor scatter, you’ll want to move to MSK144.  Stick your mode on MSK144 and go up on six meters (50.260) and listen for awhile.  You will see a “gauge” showing processor loading for each 15 or 30 second receive cycle.  It will surprise you how much power it takes.

Many systems won’t hack it, especially when you go to DEEP DECODE.  The handwriting is on the wall, and just like other things, the programs are going to require more and more horsepower as time and programming knowledge and ability move along.

Build the best computer you can afford, and know that it will work awhile before passing you by.  If you don’t, you’ll just need to do it again sooner.  Been there, done that!

You need to Right-click down in the actual list of frequencies.

As you can see in the first graphic below, if you hover over the "word" Frequency in the title, you get a pop-up (circled in Red below) telling you what to do:




BUT, put your mouse cursor somewhere down in the actual list of frequencies and Right-click.  You will see the following pop-up menu:




Just Left-click on the word "Reset" which I have circled in Red above.

You can Delete or Insert (Add) frequencies to the list using this same method.

I hope a picture is worth 1,000 words in this case.

Even if that exploit is targeted specifically at machines running Win 7 - my reading of the analysis documentation is that it doesn't explicitly verify that - it begs the question of how the WAV files with the hidden malware got onto the affected machines in the first place.  If users are stupid enough to import and then open a WAV file without being sure that it's from a fully-trusted source then it's hardly surprising that an infection occurred, and furthermore it might have occurred no matter what OS was being run on the machines on the affected network.  In my admittedly limited experience, most infections are caused by poor user procedures and discipline rather than being unavoidable because of the inherent flaws or vulnerabilities that are present in all OS's.

All very interesting, but if you compare CVE's vulnerability stats for 2019 for both Win 7 and Win 10 you'll see that there were 250 vulnerabilities identified for the former and 357 for the latter.   Also, in the entire 11-year lifetime on Win 7 from 2009 onwards there has been (according to CVE) a total of 1,283 identified vulnerabilities whereas in the 5-year lifetime of Win 10 since 2015 there are already 1,111 identified vulnerabilities, ie. there are already almost as many vulnerabilities in Win 10 as in Win 7 despite the former being less than half the age of the latter. 

Within those numbers of vulnerabilities identified in 2019 there were 100 code execution vulnerabilities for Win 7 and 124 for Win 10, so which OS is potentially the least secure???!!  Fortunately there were no public exploits identified for either OS in 2019.

It really is a good idea to move on from Windows 7. It was a good run for almost 11 years, but times have changed. Even if you aren’t concerned about your own security, maintaining a potentially vulnerable machine does put others at risk.
Whilst I agree that it would be prudent for all Win 7 users to plan for a migration path to Win 10 in the not too distant future, I can't help but feel that all the hollering about Win 7 causing the sky to fall imminently just because it fell out of Microsoft long-term support a few weeks ago is somewhat OTT.  That's just my opinion of course...  :-)

Hi, Bill:

 Thanks. I think this needs its own thread. :-|

What is not quoted here was a nice review, but what caught my attention was the quoted part above.
"What is important is how quickly it can complete the decoding process".
Yeah, that!
How do I measure that?

 While participating in that query on the RPi4 in 'DEEP' decode issue,
I noticed that, while calling another station (or was I calling CQ, anyway)
after my station began transmitting there a few more decodes appearing in the 'Band Activity' pane.
So, those 'deep decodes' were not considered by the time my station was ready to transmit.

 However, would it be a benefit to 'deep decode' a few cycles, then 'Enable AP' decode
to work that weak signal?

Chuck

Chuck,

there's no surprise here and nothing particularly useful either other than the 2 second metric. The FT8 decoder will spread a small amount of its load across CPU threads when doing FFTs but the bulk of the decoding is computed on a single CPU thread and is unrestricted so will always use 100% CPU resource on the logical CPU thread it is running on, unless it is interrupted by another process.

What is important is how quickly it can complete the decoding process, not how much CPU resource, measured as a percentage, is indicated.

The above will be the case for any CPU model or specification. Using a CPU monitoring tool that averages usage across all logical CPU threads will show a lower percentage figure for the decoding phase but that will still represent 100% resource usage on the CPU logical thread that is doing the decoding. E.g. on an quad core CPU with 8 logical CPU threads, the decoding will likely show ~12.5% CPU usage for a single instance of WSJT-X. This does not mean that the machine is 8 times better than a single logical thread machine that indicates 100% overall CPU usage during decoding, it just means that up to 7 other CPU intensive tasks could be completed in parallel without much impact on the decoding performance.

So summarizing, when choosing a CPU model the time taken to complete decoding is important, and that depends on the band occupancy and the peak CPU clock frequency. 64-bit CPUs will process the same workload faster than 32-bit CPUs given the same clock frequency, this is due to more general purpose registers being available and other architectural factors. This all becomes more critical with fast modes like MSK144 which have a high CPU load throughout reception periods, due to the near real time decoding algorithm. Again the number of logical CPU threads has no direct bearing other than the capability to process other tasks in parallel.

Another key factor in choosing a CPU is energy efficiency. If you intend to operate portable on battery power, then choosing a high end multicore CPU will likely be non-optimal. This is because, in general, multicore CPUs use more power, even when some cores are idle. A single logical thread CPU that has a fast clock frequency will likely perform better at stand-alone WSJT-X decoding than a multicore CPU with a slower clock frequency, and the multicore CPU will probably have a considerably shorter battery lifetime.
