Adam, The SSB modulation scheme that Hans is using generates true SSB. This SSB signal will potentially be cleaner than that from a typical transmitter using the traditional filter or phasing methods

KC1TQY, Please do not hesitate to join in. There is no such thing as perfect CW unless a computer does it. Everyone and I mean EVERYONE makes mistakes, stumbles, freezes, and has brain farts. It is

I have found it helpful to solder fine wires, color-coded, to the various nodes and bring them out where they are easy to access.? Makes voltage readings easy and less chance of an "oops!" slip

In my case (rev2 hardware) R306 of 33 ohm was missing. I replaced it with first a leaded 33 ohm resistor and replaced it later with an 100 ohm resistor because I found the backlight giving too much

Building on this: I've noticed a possibly similar behavior with my QMX mid-band lately, though not through terminal but simply the built-in SWR "TUNE" function. I have a dummy load connected which in

There are some voices on the group saying that digital modes requiring multiple frequencies will work once the SSB is done. My assumption is that the QMX doesn't have a proper SSB modulator, it just

Thanks guys. So far so good. I now have been able to use putty and run the diagnostics. Screenshot attached. I did this using the jumper method. After removing the jumper and rebooting (by killing

Hi Grant, There is a file with a test process for the two power supply boards in the QMX: /g/QRPLabs/files/QMX%20PSU%20test%20process.txt I would first remove the two power supply

A recently built front display rev 2? for the QMX+ has no Backlight, I am using a rev 1 Mainboard. The Backlight in settings in "On" is this a compatibility issue/duff display or are there no rev 2

On the bottom status/control bar of fldigi near the right corner is the TX level attenuator - it is by default set to some non-zero value.? You want to set it to zero for full volume from fldigi.

Thanks Oley, done. I applied your settings to Flrig, removed Hamlib control and enabled Flrig control of Fldigi. The CAT is working now and my QDX obeys. However I still have a problem of Audio (under

These are my Flrig settings. In FLDigi settings, remove control from HamLib and set control to FlRig. I think that's all. -- 73, Oleh, UY2ZA

Brien might have this figured out, though his wording is not completely clear. When Brien says:? "The point that 9V will show up as 3.3V when the knob is pressed? is output of IC101 linear 3.3V

This sounds like a great opportunity! I still have a few letters and punctuation to learn but hopefully I’ll catch up in the next couple of weeks. Will definitely listen in this week! Thanks for

I am trouble shooting my 20-10m QMX that won't start up. Thought I'd start by following the power route. I can't find X101 on the schematic. I have completed checking all solder joints and reflowed

I don't have a dummy load or an inline swr/watt meter. I will try to get those to test. It somehow went back to normal without me changing anything. So I will use it for now but if it happens again I

Hello [email protected], It feels worse than it is with reading 31 messages on one central theme. I may never finish this topic! Or, the next message Hans may announce he has SSB finished and

Many thanks Stan for your help, that was too easy. 73

Do the factory reset again.? When it reboots, it will ask you what band version the build is for.? Select the correct one.? The setting stays fixed after factory reset is complete.? It cannot be
