Turn the DRIVE up even slightly! See if that fixes it.

Josh, Not sure if this is what I see - but it looks very similar. If you did a wider display I could tell better. I see these all over the place and had assumed they're interference signals from somewhere outside my property. I can peak them in a particular direction often and lower antennas general...

I believe it was Brent that suggested to turn off MAP and turn on STBL ... I wrote a note to myself to try this and finally today did indeed try it. For me this reduces (makes worse) the IMD by 10 db. Leaving the defaults on, MAP on, STBL off, makes it better. This is two tone testing. That was howe...

Carl, Yes I realized it was the coupler screws... I was just commenting on the fact that for feedback to occur you need a source and a load... you need to 'complete' a path ... that could be to the case, although if your antennas are close by that might be a path. not kicking improvements ... as an ...

Carl, Color me sceptical. We're talking about systems that are 'sealed' essentially most everywhere. So the covers on the radio for example... they go a tremendous way to keep RF out ... the cabling has a shield on it and has very little leakage especially considering the distances covered in the sh...

Carl,

Did I miss something - what did you do different? And were you experiencing the 'blow-outs' on 40 previously?

Carl, This is not what I'm seeing, at least re longevity. Mine is only there for a very brief moment - maybe 1/4 second or so... possibly 1/2 second... I don't remember what the lights are doing but I do believe the right one remains green. Scott, I'm not talking about the FT8 issue here. this is on...

Carl, I've reported this action previously.... it is there every once in a while. Just BLOWS UP the screen - is 10's of Khz wide - and I can't imagine what others on the band hear - has to be horrendous. It lasts for a split second but then it takes another couple of seconds before PS comes back wor...

oh believe you me I do! There has to be 50 DB versions in that folder. What had me going is that the db i was using WAS stable on the i5 computer!! But it wouldn't run on the i7. So I went back a couple months (very little changed in that time frame) and that seems to have me back in order again. so...

ok - so I went back to an earlier DB and it worked initially ... I've just restarted the computer so we'll see.... ok - good, it all came up. Strange that the DB would not work on the new computer but didn't give me any issues on the previous one! Go figure THAT scenario. I THINK, he says cautiously...

Scott, not sure what the link is suppose to do for me. Mine won't start after the first time it is run and then closed. And I'm getting no error message other than Windows saying it has to close.

Gary

ok - so its working again - kind of and then not ... I didn't delete the database file like I thought i did. Doing that allows it to start up again and of course nothing is "right". I then select, once again, the latest DB file (that has been working for a very long time with only very sma...

This has been running for a year and a half or so ... I recently bought a new i7-8700 computer more for future proofing than anything else. so ... MAJOR failure... so I got everything installed, I think ... VSPE, VAC, log, WSJT-X, PowerSDR. Had PSDR running with my latest DB and with all the VAC set...

Gentleman: Hopefully this will be the last report to this thread. So - I got the replacement i7-8700 in, this is a Pavillion 590-p0070. The first one had reasonable PassMark PerformanceTest marks for the CPU coming in at 14840 (the "nominal" over what appears to be hundreds of submissions ...

I've had the latest running for a long time now and have never noticed this before until a couple days ago. I don't know if this is a bug or if intentional and if intentional how you "control/change" its behavior. So you have the "STEP SIZE" boxes at top center. + and -. And I of...

Hey Brent - I fancy myself a history buff - but I can't tell who the picture avatar is ... ? So ... I just did an OS restore. I believe all computers now ship (if pre-built) with a partition on the HD with Windows files/installer. So I just ran their utility to do that. It bought it back to where it...

so I spent the whole d#$* day working on it ... I went back to the original HDD alone, tried the SSD alone... tried various settings etc ... always the same results - around 11500 ish when the first test gave me a 14480 and the nominal is around 15250. I even saw one result that was at 10,700! That ...

I'd "accept" that except for when I tested this computer, the 5+ year old i7-4770, it's rating is spot on for this processor results as shown by PassMark (showing hundreds of results). I didn't do anything to this computer before I ran the test other than start it up. Also we're talking 19...

so that new computer that i have ... it is an i7-8700 3.2Ghz ... it ran a 14800 on CPU/Passmark test 2 weeks ago or so ... today when I run it it is anywhere from 11500 (tops) down to 10000! WHAT CHANGED? I can't figure out why it would drop so much. That is a huge difference and its now running abo...

Joe, Agreed ... however there are LOTS of things running ... I don't know how programs that do not run multi-thread (if that is the right term for actually using multi-cores by design) end up using a core ... if they are only typically on a core - then unless there is some randomness on how they're ...

and I tried changing PSDR to just one core - core 6 on my i5 (6 cores total) ... there was no change that was obvious. The CPU usage was the same as I'd expect it to be ... note my thought on this is that if one were to do this you'd want to have the programs you're concerned with, for example WSJT,...

I'm curious ... even though I'm an embedded designer both HW and SW I'm not familiar with the details of how a PC handles interrupts. So I'm throwing this out there... I have an old program that is used to download firmware to the product that I sell ... and for it to work reliably I have to set the...

Joe, Thanks for the post - unfortunately some of this doesn't relate directly to my setup where I am using, what is it WDS or something like that under VAC ... I'm using VAC-M (Eugene's) ... I'm not sure how I'd edit the network 'card' ... for me its going through a 1Ghz switch then to the main comp...

Just as an aside, for me an important one, I had changed that setting: CONTROL PANEL | SYSTEM | Advanced System Settings | Advanced then the top line "Performance, settings" selection ... it was defaulted to "let the computer decide" and this improved or reduced the latency issue...

ah - apologies then (re PTT on vs. off) ... I'll check out using this method myself.

so apparently I lucked out and hit some of the items that need to be (re)set. I added another one after that last one - I don't remember where it was ... the new computer has now run for over 6 hours and still is "acceptable" ... although I suspect JUST so as the one category that it previ...

huh? Its been a long while since I first set it up but I don't quite get why you both say/agree that Enable PTT should be OFF! It has to be on - or at least it IS on for my situation and it is configured from within WSJT to use it as a (separate) com port.

Re: LatencyMon, a setting change and a bit of improvement So I ran my current shack computer, an i5-4460 on LatencyMon again - ran it for over an hour - never fell out of "suitable"! This new super fast i7 within 30 minutes would fall out ... frustrating. Then I found a setting I hadn't se...

Thanks Scott... unfortunately a search is only as good as knowing what to search for - I searched for Latency Monitor, not LatencyMon! So now they're both linked to the same thread. Ok - I'll keep trying to find out where I get access to tcpip.sys... I looked under Device Manager and wasn't able to ...

actually the passmark on the CPU is 14842!
