Well keep it in mind John, Unfortunately since resetting the DB would also set the ATT to 0 we don't know! .... the fact that only one band was showing it says you might have turned it on and forgot about it ...

just a thought.

g.

I will take a guess as to what you are seeing: you have some level of ATT selected on 40M! Just set it to 0 and you'll be back where you 'need' to be. Nothing else needed.

this assumes your natural noise level is at that level ... in which case it is a moot point.

Great - I had forgotten about the post so my bad anyway. Drop me an email at my arrl email address if you have any other questions regarding its setup or use.

Hi Ron,

I'm using the CMD 2A and love it! I do indeed have VFO A and B assigned to the 2 wheels. I'll check the 'settings' in the midi panel.

I have to say as a design engineer this sounds like a "myth" ... timing issues based on what would essentially be a small difference in temperature. Sounds more like there is something that is not right in the interface and its protocol or the chip is not designed to do what is being asked...

It is unfortunate but the DCE vs. DTE format is not always followed on devices. [these tests are done with the amp not connected to anything on the RS232 lines] So ... It's easy to determine which is which - TX vs RX.... use a meter - assuming you know which pin is ground (test to chassis if you don...

I've had no issues with windows updates until very recently when it caused the audio, using VAC for FT8 digital mode, to be distorted. Scott had suggested I uninstall and reinstall my VAC program (the one by Eugene M) ... I did go back to the previous version of Windows and it worked again but I don...

Rubern, Agreed. They DO update quite often. It's more a pain to get it 'in' than anything else. Until this one mentioned at the start of this thread I've never had a problem and reinstalling the VAC program solved this problem so not bad overall. I don't think delaying it helps - ultimately if you a...

SOLVED I went (back) to the previous version of WIndows ... and all was working again. Been that way since 26 July when I first started this post. But as mentioned I don't want to orphan my computer. So I took Scotts suggestion. As usual he was right. I downloaded the latest version VAC (Eugene's), ...

I never had an issue running the 8000 at 60 - 70W on FT8. Didn't get very warm at all. But again: you've not addressed my comment - this looks to have no relationship with temperature - or am I missing something? It looks like you have a nearby noise source in one shot (the -67) and that noise sourc...

I'm confused why you went to suggesting a fuse on this? It looks to me like you have TERRIBLE noise at your location and it simply went away! -101 is a little bit high for me here with a 2.4Khz passband ... and -67 is terrible noise - but it appears like I'm seeing the same signal and not seeing the...

I rolled back yesterday. I've never done that before - never HAD to do that before. It fixed the issue. So what does one do going forward? I of course don't want to be stuck in time with an ever aging version of windows sans whatever security is needed ... will Microsoft "realize" this and...

when I said I switched back to an older db - I meant one from a few days ago, that was working fine before this latest Windows update ... Gary

I've not had audio issues in a very long time ... but yesterday Windows took me through one of those wonderful update sessions... the latest, installed on 25 July, 2020. Since then my FT8 audio isn't working. Its mush. Distorted audio ... and the transmit is no better. I reset to an earlier db, a fe...

On topic per the subject line but a different take: Setup: This is independent of PS. DUP is on. 8000DLE, Xytronics coupler with an additional 10 db (54db atten inline). Amp: Elecraft KPA1500. So - when I transmit using CW, DIG (FT8) and even 2 tone the TX display always shows or 'peaks at or just a...

A couple of comments from my experience. I had drop out sequences where nothing would decode - frustrating especially the few times when it was someone I needed and I was working. Turned out to be my fault. I had Dimension4 time program set to update once every 10 minutes or something like that - no...

Seems a reasonable conclusion you've come to ... I've not bothered with the resampler for a long long time. Just don't mess with it. Seems almost a solution looking for a problem. Since perturbations in CPU action elsewhere cause clicks and jumps in the TX signal - and since these also induce the re...

N8UR: coincidence! I use MME and see them. My strong suspicion is they are real! I had one local station the other day that was literally 210 Khz wide here! He was a +16 ... and had a scalloped signal down more than 100Khz and up the same! I took a snapshot of it to send to him but it turns out he i...

Tony, The NB settings are default (although I've changed the ... threshold I think its called (not at radio) to 15 from 32, makes no difference to this subject though) ... I've not had any issues. There's no reason that i'm aware of that you shouldn't use a NB on DIG modes! NR yes, but not a NB. I u...

thanks guys - I stand fully corrected. Keep up the great work.

I see this quite frequently. It has nothing to do with PSDR. It is the quality of transmitters as they go higher in frequency seeming to reach a crescendo at 6M! Note further I use the NB (both NB and NB2) on 6M all the time - no impact at all ... HOWEVER if there are strong nearby signals - like CW...

not in direct response to your posting but definitely in response to your heading for this thread: I played with the NB settings... and found that a THRESHOLD value of 15 is about a 1-2 db improvement for me over the default setting of 32. Consistent - audible - seen on the waterfall and on the S-me...

John, W1JA, after reading your comments re freq cal and improvements on FT8 I was quite confused - I couldn't see how there would be any connection or correction for that matter by doing this since FT8 is relative and not absolute (its not tied to an absolute frequency)... but I did it anyway - and ...

I recently read the section of the WSJT manual regarding the measurement tools. There is a "linearization tool' there... and it is stated one can use this to get this correct OR if one has the ability to do Linear Phase on TX (vs Low Latency) that you are set to go and need not worry about this...

thanks for the step by step - but when/how did you install Thetis itself?!

Gary

Thanks Scott... well this is what happened post my note - it might be germane to someone seeing/using this thread. -this morning, with everything powered up 24/7 as usual, I tried to work someone on 60 FT8 - no transmit signal. It went to TX but nothing showed on the TX pan. Tried this and that - re...

I've named this topic - now just need to know what to fill in for it. I've had very good success with Eugene's VAC and FT8/MSK144 for a long time now - I've never had an issue where a Windows update seemed to bother anything. But I had an update 2 days ago (i believe it was) and now I have audio cli...

Thanks Scott ... Bhanu, Sorry for the issue. Interesting that your signal is not getting decoded. When you are transmitting do you see the TX display on Thetis? It should show a very tall rather thin profile and it should be shifting slightly left and right... its peak should be 0 db. Are you seeing...

How do you know its not just propagation? Or the station chose not to call you? Have you had zero success after many tries? Also your TX power slider seems down a good bit - set the TX meter on Thetis to ALC and confirm the level is -1 (set it to this). But I do have to say I see why it is often dif...

NN3RP (no name at the end) ... can you provide links for these pictures please? - the pertinent ones (not sure why there is a cable/coin in the one) ... these are not readable as is.

thanks
