Re: Resampler Adjustment

Hi Scott, Observant question! I should have explained more details. It wasn't in FT8 mode - it was in Freq Cal mode in DIGU, VAC on (of course). But since I had been previously operating FT-8, the remnants of my previous QSO were still in the entry slots. I'm holding out hope that some combination o...

Re: Resampler Adjustment

Posting my results, using latest versions of SW and FW on ANAN-8000DLE. One is re-samper-on ("Force" unchecked) and one is re-sampler off ("Force" checked). In a one-minute time period at 15 MHz (WWV), I get 0.297 Hz variation checked, 3.4 Hz unchecked - a factor of 11.4 differen...

Re: Resampler Adjustment

Gary, JT is of course correct - but I don't believe John (W1JA) was asserting that the WSJT-X cal function improves things (we have discussed it). He used WSJT-X cal only to observe frequency instability in Thetis as a function of the Thetis resampler setup, and saw a 10x difference in frequency sta...

Re: 7000DLE Mk-II PTT IN issue?

I guess I don't understand the problem. First - are we talking about Thetis or PowerSDR? The original post said PowerSDR. Also, historically, "full break-in" was used a lot to mean semi break-in with the delay set to zero. That's not QSK. In Thetis, I have a logging program controlling PTT...

Re: 2.6.9

I haven't looked at the code yet but here is some conjecture. QSK works so well because when you key the radio in QSK mode, Thetis' involvement is minimized and round-tripping is eliminated. That's not to say Thetis can't be involved. CWX works just as well. And since these antenna connection choice...

Here's another interesting clue: The effect is most pronounced when tuning with the MIDI wheel, or dragging the VFO in the panadapter display. It's less noticeable when tuning with the mouse wheel but is still there. The last time I looked at the CTUN code was a year or two ago so I'm a bit fuzzy on...

CTUN artifact

I like to operate in CTUN mode. That way the display stays constant while I tune around. I've noticed for a while that I can hear artifacts on some CW signals as you tune across them - not all of them, just the stronger ones. I filed it away as something to investigate - annoying but not severe. But...

Re: Thetis QSK and the new default low-latency filters

The artifact isn't immediately noticeable on SSB, but over time, you begin to hear it as a resonance at the high end of the filter. If you can't hear it at 3kHz, go down to 2.5 or so and listen for it at the high end of your QSO partner's audio. As you pointed out, Bryan, it's also possible to hear ...

Re: Thetis QSK and the new default low-latency filters

Guys, I don't believe this is a ringing issue in the usual sense. It's more like a resonance in the Low Latency filter that happens in *all* filter widths and tracks the cutoff edge furthest from the carrier (i.e. the highest audio freq). I first thought it was a resonance in my headphones that I'd ...

Re: 7000 and 8000 Protocol 2 users: what say you?

Hi Rick, Just thought I'd chime in on this latest. I'd been running 1.5 with Thetis 2.6.2 for a while - since you released 1.5. It was quite stable and PS was working consistently - the main difference from 1.4 where it was randomly quitting. With 1.6 all seemed fine. But in an extended QSO on phone...

Re: Accuracy re fidelity on/with the TX display while using PS

I read it, Stu (I read nearly everything ;-). Your math makes sense. I think your point, put another way, is that PS corrects for net IMD through the entire transmit chain, exciter plus amplifier. This means the output of the exciter alone has not been corrected optimally. One wants to make sure tha...
