Re: Simple and very tiny mic for the QMX.
#qmx
#ssb
I try to repurpose that stuff all the time. Did it have that ribbon wire in it? Thats the wire with laquered ribbon wrapped on some kind of poly thread that's? impossible to solder; found in most ear bud/mic sets.
?
If so how do you solder that stuff?

Re: Software Development and Requirements Creep
Either way would have been fine.
?
Releasing SSB firmware for 80m only, no CESS, limited menu, no support for CW or digital modes,
no calibration step would have shut down the "This EER SSB Stuff Can't Possibly Work" posts.
And many here would have been happy to try out an early version of 80m SSB.
?
Pushing through and releasing it in more or less final form may be for the best, assuming Hans recovers.
It's mostly bug reports being reported, often stuff Hans wasn't aware of, not reports of needed additional functionality.
It would have taken months for Hans to find those bugs, releasing piecemeal would likely have a larger total bug count,
more documentation to write, more discussion in the forum.. All at once makes best use of his time.
?
I'm just happy it's out, and that it mostly works.

Yes, I believe you are 100% correct. Much of it could indeed have been released piecemeal as releases in their own right.?

If you had then I think there would have been a massive amount of demands for the additional features to be added NOW!? There would have been massive criticism.? The "are we there yet" posts would have? been replaced by "I want it NOW!" posts.? This would have been far more stressful and harmful to the QMX Labs reputation.

I tried changing the 80/20 band swap advanced setting and it didn't fix the problem, but it changed the behavior a lot. It now runs longer before quitting.
?
?
In another thread, others with this problem are suggesting that the configured center frequency in the band table might have something to do with the problem. I believe that's used as the frequency to run the tests.
?
I'm thinking I may have to improve the BPF center frequencies to fix the problem.

Re: Odd 20 meter calibration
My version 1 PCB installed an earlier band table with the band centers on the FT8 Frequencies. I'm having this sort of trouble on 80 and 40 meters.
?
I think there may be a problem if the test frequency is too far down the slope of the BPF curve resulting in low signal feedback for the tests. I've mentioned it to Hans and he told me to try changing the 80/20 band swap, but I haven't quite figured out what he meant yet. ?My BPF filters are skewed quite a bit on some bands (but the manual indicated this was nothing to worry about at the time).
?
I'll try to figure that out, but I'll also try moving the band centers and see what that changes in the calibration test.

Re: FT8 in USB mode - not working right?
Also duplicated this exact same issue. I spent time trouble shooting but found no solution and now just switch to Digi when needed.?

Re: FT8 in USB mode - not working right?
At first I tried clicking the "Update hamlib" button in WSJTX. This did not fix the issue. So I copied over the latest manually. WSJTX will now allow me to select the QMX.?

Re: Software Development and Requirements Creep
Well said John. I agree with you.
I rarely post because I believe I can learn more from listening than from sharing my limited experience.
?
I'm a customer of QRP Labs, and as such, I would like to add my opinion to this discussion about Software development. From my point of view, what Hans has offered to the amateur radio community is more than a great little radio. It's a chance for a consumer to have a glimpse behind the curtain and the opportunity to have meaningful input.?
?
The one outstanding feature that Hans produces is the engineering that goes into his products. From a consumer's view, that is what stands out. I appreciate the chance to watch something wonderful come into the world. Congratulations, Hans... and my thanks.

Re: FT8 in USB mode - not working right?
The advantage of USB mode over DIGI mode is the ability to control the power level. DIGI is my preferred mode but there are times when reduced power is useful.

I have also duplicated the problem in running FT8 in USB mode in WSJT-X.
After the first transmission of the automatic exchange, it won't transmit again.
?
My first note: FT8/FT4 will always work better in digi mode, so why are we trying this??
So a fix may be low priority, unless this also affects other WSJT-X modes that need SSB mode.
?
Anyway, I tried to diagnose it a bit, changing settings and VFOs used, etc.? I tried what I think is the least complicated settings, for radio control, i.e. setting both 'Mode' and 'Split Operation' to 'None', and setting mode manually and selecting VFO
A.? But the problem persists.? I turned on the QMX CAT log, and observed the commands sent to QMX, and I see the correct commands being issued, but on the 2nd cycle when the TX command is sent, for some reason QMX immediately reverts to RX mode (per its log).
This same action happens on successive cycles.? I have no idea why.

That is puzzling and suggests that there is a another cause that is not understood.? In my case I also had an issue where my QMX was? transmitting on a different frequency than was displayed on VFO A. It was the Frequency center in the Band Configuration for 20 meters.? In a separate post, I noted that this was only resolved after running a re-callibration, but it seemed to also point to the Band configuration involvement.

Simulation of #QMX Filters + planned 6m in QMX
#qmx
Hello,
?
80-20m is my first QMX Kit, QMX+ (160-6m) my second, now I purchased a 20-10m QMX Kit.
I am using the QMX+ stationary, the smallones I want to use in portable operation.
80-20 and 20-10 means:? 2x 20 m and no 6m band.
The idea is to modify the 20-10m to 17-6m.
The first thing I do is studying the schematics and creating simulations with the original L and in ngspice to get a feeling.
If you are interested, here are the files:
