Do I need to do the calibration to listen to SSB and will CW and digital not be affected if I load the beta? I haven’t done anything about a mic yet but want to see how it sounds on RX without

And here's more info from Qrpguys that was apparently published before turning the mic design into a kit. Be sure to read the kit instruction manual (from the above page)

James, that's pretty typical, and mostly due to variances in component tolerances, toroid winding differences, your output transformer, etc. Nothing to be worried about. -- 73, Dan - W2DLC

This SSB update is fun to use! both on digital and SSB modes.... Thank you so much, Hans! But in the interest of finding bugs to smash...: I attempted to do Calibration from the front panel on the

Thank you gentlemen, I was able to send an email last night at level 6. What's the best way to set up for switching between Winlink/VARA and JS8 call? I noticed in JS8 call there's a radio setting

Thanks Brian . I am reluctant to try the SSB firmware. Mike Krieger [email protected]> wrote:

I am seeing this as well. Attempting to do calibration from the front panel hangs at 80m 1300 measurement. I wanted to run it from the front panel because I have tone spurs on some bands that go away

Congratulations and thanks to Hans! Conditions were good enough to make my first contacts today on my QMX on 20m. I built K6ARK's microphone (

Thanks for the quick feedback. Indeed the problem was me :) I discovered some not properly soldered joint and now everything works.

Yes, the same SMPS boards work on all revs of QMX and rev 1 of QMX+. [email protected]> wrote:

Hans loving the SSB, I've put together a tiny mic for it the audio seems really good, all your efforts were worth it . I would just say to anyone using the SSB firmware before you plug any type of mic

Yes, definitely something is wrong. Perhaps if you bring up the terminal diagnostics page that shows the power supply parameters, then turn down the voltage to just above where it turns off, it may

Nice catch, Mario. I just verified that using the sequence you just described, then attaching the terminal and sending the CAT MD command to the radio, it responded with MD9, which is reversed

Last night I downloaded the latest firmware and threw together a rather basic microphone, and after going the the calibration tests it appeared to be working well into my main station transceiver.

Thank you Dan, I've removed the battery pack out of the equation and I use my lab linear power supply which can deliver 1A. I let the QMX in receive mode and I slowly decrease voltage and suddenly it

Hi All, I enjoyed spending two evenings with my QMX 20-10 ver 1.01 and 1.02. N oticed some oddities during calibration o n 11 and 10 meter bands , calibration does not complete on 11 meters , stops

Anders, Presuming the QMX is like the QDX, in IQ mode there is no 12KHz offset. The QDX manual has a good circuit description. 73 Alan G4ZFQ

jd I believe the QMX+ Rev 1 use the same SMPS boards as the QMX Rev 4. 72 de Russ, va3rr

Another thought... Make the whole mess into something that's mounted to (or under) the Key/Paddle and use it as a convenient junction block where you plug in your headset! M

Here's an interesting idea I just had! I usually prefer to use TRRS headsets myself - since they're clearly the most widely available and inexpensive choices, so I built an adapter similar to what
