Re: WSJT-X FT8 signal images

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...

Re: WSJT-X FT8 signal images

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...

Re: WSJT-X FT8 signal images

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...

Re: WSJT-W and Thetis 2.6.9 & DLE-8000

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...
