Re: LatencyMon Benchmarks

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 ...

Re: LatencyMon Benchmarks

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,...

Re: LatencyMon Benchmarks

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...

Re: LatencyMon Benchmarks

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) ...

Re: WSJTX AND PWRSDR 3.4.9

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.

well that's a start ... but that is still high. What band was this? And you're sure there is no antenna connected at the rear jack?

Also what filter width?

Re: S meter reading

I tried the above (last post) on 17M ... and saw what I indicated ... of course those results will indeed depend on what kind of impact the NF has on the front end. Generally on the lower bands it won't impact the results ... on the higher/highest band it will... here on 10M I see 28 db difference w...

Re: S meter reading

ok....but if you have ATT set then the noise floor goes UP and the S meter goes up as well! So yes it is taken in to account which is what he is seeing! I just set 30 db of ATT and my noise floor went up and my S meter went up ~ 4 S units or 21db roughly in the dbm reading...which implies I believe ...

Re: RX1 AF level with WSJTX

FT8 has proven to be a serious threat to activity in all other modes on the bands... in the past when conditions were just marginal I'd be able to work lots of DX say on 15 meters (using 6/6 stack) ... but now even with signals, MANY of them on FT8 and levels well above +0 there is for all practical...

Re: RX1 AF level with WSJTX

I know if I see a signal that is pretty strong and it decodes twice or three times during the same cycle, seems to be smeared on the waterfall, then I need to reduce the AGC gain. Other than this, it is really all a guess for me. Joe W4WT Joe, Is this true? I always thought those smeared double and...

fascinating and sad story ... but I believe few would have pulled it up ... Thetis is probably still 'safe' for that reason.

I believe I have done all this multiple times with both the VSP from MicroHam KII and also Eterlogic VSPE ... but I'll take a look, hopefully I missed something ... note this doesn't explain why CWX doesn't work and as a matter of fact 'acts' identically to what N1MM+ produces.
