Could someone please have a go to try and explain in simple terms what the alignment process on the QCX actually does ? I understand the manual says to do this once construction is complete. But are

I disagree, as you can clearly sense their agenda. You don?t even need to read between the lines as both make their personal issues with us/me relatively clear. We decided against "jumping through

I think this is a very interesting read on uSDX/(tr)uSDX, a lot of interesting info here: https://vk2ihl.wordpress.com/ And: https://owenduffy.net/blog/?p=28224 73 Hans G0UPL http://qrp-labs.com

That?s pretty vague and too anecdotal for a technical person, like you. I can?t really tell what went wrong on your "brassboard" but I assume, you?ve used old QCX SSB Code. Same goes for QCX: QCX

See what emissions you can receive. Newer rigs tend to have a soundcard built-in and connect directly to a PC via USB. Older rigs benefit from a digital interface like signalink that can also connect

And join the "FT8 Digital Mode with WSJT-X" and "WSJTX" groups right here on groups.io.

I figured out how to run FT8 mostly from reading Hinson's guide. Here is a link, I'm not sure if it's THE link. http://www.g4ifb.com/FT8_Hinson_tips_for_HF_DXers.pdf

To answer my own question, I put my QMX (midband, rev 4, f/w 026) in FT8 on WSJT-X on 14.074. Lots of strong signals all over the sub band. I then changed the band on the QMX (NOT using WSJT-X) to

Well I still have my brass board work.? I pust the QCX back to its nominal design. I was given a recent version... tried to talk to the local usual group and the response was sounds terrible, is that

Go into system config, selection band limits, and select 'none'. P.51 of the ops manual. That should work. 72 de Russ, va3rr

Hi after Updating my firmware from 021 to 026, a good new functions like 50 to 600 Hz filters for cw is possible. Good stuff. but now it?s not possible anymore to tune the 60 m band. 5.332, next step

Mark, L4/C30 in QCX forms a parallel resonance circuit as part of the class-E amplifier. In the uSDX this was changed to a series resonant circuit (adding a L in series with C30), making L4 frequency

John...Is that true with the QCX? It uses a class E PA which, as I understand it (admittedly imperfectly), needs a resonant input circuit. In the case of the QCX, L4 has different values depending on

I have a cheap camera microscope that really helped checking my work as I went along. And extra strong reading glasses. I just wish that I would have used it to check the power supply boards before I

Greg. ?No peak to peak is twice the peak value ptp /2 is called peak for sine RMS is 0.707 x peak

I took the QMX to work to use their? high power binocular microscopes and found that the end pad of C509 looked like it had a crack in it. I replaced the cap and everything now looks like the

Hello again folks. Shouldn't the procedure/formula be: Measure Peak to Peak Voltage ( after the LPF filter) into a known good 50 ohm dummy load.?Multiply that figure by 0.7071 to get RMS

Hi Mark As with most of Hans kits the QCX has the ability to become a multiband XCVR The low pass filter (LPF) is primarily the band ?defining element Donot install the LPF on the main PCB You will
