Dudley,

Your post was not “needless”. ?There are new member to this list every day and rehashing some of the common issues helps to bring new members up to speed. These things happen and we only get answers when the question is asked. ?And some of us 80 year olds need to see it a couple of times to have it stick. Ha! ?

This is a hobby and hobbies have new starts at all ages and abilities. ?I have been following this list for years and continue to learn or re learn things that I should have known from my 65 years in this hobby. ?Rehashing an issue or problem helps us slow learners get with the program.

Paul,

For years I would break something so I could learn about it by doing a repair. ?BUT over the years I have backed off on that idea and especially on the small hf rigs. ?If yours is working to your satisfaction on the bands you use just leave it alone. The tight placement of parts means being “perfect” in your removal and re-soldering the part back in. It’s so easy to damage other parts while doing that. Please enjoy the mini miracle you have on your bench.

Have fun.

thanks for the information.

I don’t use 160m as i don’t have the space for a antenna but a increase on 6m would be useful

thanks for a cracking kit had a few 20m & 40m FT8 contacts yesterday

well impressed

I think that power control would be nice anyway and doing this on a band? by band basis would be a minor addition.

Re: Should I just go ahead and order a QMX+?

 

Hi Hans,
many thanks. I have actually been holding off ordering any of the QMX range in anticipation of the release of the QSX. Not built anything in ages so I am looking forward to the new QMX+.?

Re: Should I just go ahead and order a QMX+?

 

Hi Ken

Currently we're shipping QMX+ with 1_00_027 (not SSB) while the SSB firmware is still so new and beta.?

Firmware updates are extremely easy to install though.

I've wondered if the second stage of the 10W linear could be hooked into the QMX between the existing PA and the LPFs, sort of where T501 is.
Chris,

Anything is possible but is it worth the trouble?
Often it has been remarked that 3dB improvement (1/2 S point) is no big deal.

On the other hand an external 20+ watt amplifier would be neater, more effective and a lot easier to implement.

Re: QMX and WSJTX. audio problem

 

stupid but it took me some time to understand. The COM Port can only serve for one program so if you have i.e. a logging software running with the QMX WSJT-X will not connect to the QMX. In my case I have to start WSJTX before the logging software and then that won't connect to the QMX+ however WSJTX does report to the logging software if set up to do so. Also wone thing fooled me at one point. I got messed up with the audio settings and all of a sudden the QMX showed up as QMX...3 and not 2 so I had to change that in WSJTX. Also I had to set the Audio higher as the default 54 on most bands.

As a lurker with a QMX+ kit in a sealed box waiting behind a few other projects, "The capacitors are trained to hide in the knobs on these kits" is exactly the sort of nugget I'm looking for!

Hi Stan
Thank you for the quick reply.? I bypassed the LVDO but it made no difference.? But I will try another source.? Thanks...

I would first try a different power source.? Maybe something in your new LVDO is limiting the current such that QMX+ can't complete its startup.


Re: #qmx #SSB Firmware beta 1_01_002 release #qmx #ssb

 

Hi
After installing an outboard LVDO voltage regulator (ND6T circuit) my QMX+ boots up to show "Initializing: Audio system" and doesn't respond any further.? Putty doesn't respond either.
I have used the 'forcing update method using wire jumpers' which allows me to reinstall the firmware but to no avail.? The QMX+ just reboots to the "Initializing Audio system" screen and goes no further.? I have installed an earlier version of the firmware 026, which installs ok but still just goes to the "initializing audio" screen.? I have also reinstalled the new 003 firmware but just the same problem.
If I remove power and press the right button before powering up, the first screen shows "Initializing: Setup EEPROM" before moving on to the "Initializing audio" screen and locking there.
I have checked the input voltage at 11.5V but I can't check much else.
Can anyone offer some advice on how to proceed from here please.? The QMX+ was working fine with the SSB upgrade until this happened.
Regards

Re: SSB audio distortion #qmx #SSB Firmware beta 1_01_003 release #qmx #ssb

 

Try turning on the EQ then set the EQ to +20. Listen on another receiver for a change. My QMX would start to get raspy at a setting below +14. I set mine at +20 (max) and it sounded pretty good. Then I set my mic gain to 63 and compression to 5. It definitely made a huge difference in quality on mine. It was distorted and virtually no power output. I was able to make a contact on it to Kentucky after I changed those settings.

Re: SSB Mike wiring?

 

You can get further on 3W than you might think, I was quite surprised.?

The PTT signal is already avaliable,? but needs configured.? There is no time line for the Basic code - I think you could likely get your favorite microcontroller set up on the dev card much faster.

Or should I wait to see what's coming out at Dayton that will be even more amazing? But then I won't have time to get it ready for Field Day.
