Thank you very much Stan! Will try in the evening.

Re: Available Hand Mics for QMX SSB ?

 

I can print them faster than I can assemble them. I have 3 3d printers at my disposal.
?
My biggest hold up is waiting for Amazon to send parts when I run out. Interestingly the bubble mailers that were supposed to come on Saturday never made it here, but the second set I ordered arrived today - so I was able to send out everything I had ready - which was all the kits that had been ordered and a little over half of the assembled versions. I should be able to catch up by the weekend and then be waiting for parts again. I can print the cases faster than Amazon can deliver the parts at this rate. :)


Re: Qmx Ssb intermittent transmit.

 

Howard,

Here is the?KobiConn parts number?from Mouser:? 161-5435-EX

As a TRRS Jack the following?pinout is expected.? See PDF drawing attached.

Pinout:
Contact A is Tip
Contact B is Ring 1
Contact C is Ring 2 (no contact - unless you want to wire as a TRRS Jack for a standard CTIA TRRS Headset)
Contact D is Sleeve (the longest Terminal)

If?you want to wire it for the CTIA TRRS Headset (US Standard and most of the ROW) then?
Sleeve is MIC+ (yes, that's correct)
Ring 2 is Headphone Common and Mic-
Ring 1 is Right Headphone
Tip is Left Headphone

Then you could run VOX with the TRRS headset.
Or add a second Jack wired: tip to PTT, Sleeve to?Ground.

It takes plenty of force to seat it completely, but it won't fall out on its own.

Re: Difficulty after loading ssb firmware beta 1-01-03 on QMX+

 

The strange thing is that this was a working QMX+ until I initiated the upgrade. Thinking back on
the procedure I did was:
?
Initiate upgrade from menu.
After QMX+ drive recognized by compute, go into file manager.
Select QMX drive.
Delete 1.00.27 image.
Copy 1.01.03 image into QMX drive.
Power down and re-power booting up 1-01-03.
?
Maybe I should not have deleted 1-00-27 first. Maybe that started the confusion.?
I’ll look at these things tomorrow?
?
thanks for your responses,

Re: Difficulty after loading ssb firmware beta 1-01-03 on QMX+

 

Hmmm...? sorry to hear that.?
I have upgraded 3 of my QMX, and downgraded 2 of them, and never encountered a problem with the receive audio.
So this is certainly not normal.
And yes, Factory Reset should reset all of the settings, so that shouldn't be the issue, either.
Is your audio gone regardless of which mode?? (CW, Digi, SSB)?
And it makes random pulsing noise but no signal reception?
Is this QMX+ a rev1, rev2, or rev3?? This sounds almost like a PCM1804 problem, but that should be rare on a rev2 or rev3.? And shouldn't have anything to do with a firmware update.
I recommend you use the terminal to do an Audio filter sweep, RF filter sweep, and Test ADC I/Q (for one selected band, with dummy load attached).? The results of those sweeps should give us a clue.

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

 

If you make a parameter change in the terminal, say turn off CESSB, is the change immediate or do you have to exit terminal mode or exit the sub menu?

Re: Difficulty after loading ssb firmware beta 1-01-03 on QMX+

 

I failed to mention that a did a factory reset in both versions and that no stations can be heard through
the receiver. The menus are completely traversable. My gut makes me think that the stored settings are?
now corrupt and confusing the the two firmware versions. I would think that a factory reset would
default the settings according to it’s respective version, in both parameters ordering and values.


Re: Available Hand Mics for QMX SSB ?

 

If you want help printing the cases I can make a few.

Re: Difficulty after loading ssb firmware beta 1-01-03 on QMX+

 

Maybe a conflict with one of your settings?? (there shouldn't be such a thing, but there are still unknowns in the new version...)
Try a Factory Reset, which will restore original factory settings.
Note that updating firmware keeps existing settings intact, so doing a 'factory reset' may help either firmware version.

SSB QMX FIRST Contact

 

I was excited to try SSB on my QMX but my microphone was in my home QTH Michigan.

I ordered the electret element that Hans recommended and assembled a microphone from spare parts. About $20.
I downloaded 1_01_003 hooked up my 20M 1/4 wave vertical and looked for a POTA station to call. My first call was to a station in IL. I am in FL and got a 55.? My second call was a station in Al and got a55.
Now I can slow down and do calibration. What a blast!

Difficulty after loading ssb firmware beta 1-01-03 on QMX+

 

I was excited to load the beta SSB firmware on my working QMX+ Transceiver. It was originally?
running version 1-00-27 very well. ?The SSB firmware loaded apparently fine and booted up.
however it appears that something is wrong with the receiver side while the transmitter provides
normal CW output. ?I see some sort of noise pulsing at random in the audio output and see led
burst on the S meter. ?In my process of troubleshooting I tried to return the QMX+ to it’s original?
configuration by loading the 1-00-27 firmware which loaded but demonstrated the same results?
As the 1-01-03 firmware. ?Multiple reload attempts resulted in the same. I am at a loss as what to
do next. It seems that something went awry in the initial loading process. Any ideas?


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

 

Open device Manager and expand the Ports (COM & LPT). You will see one or more COM ports, one of them is the QMX. You can determine which one by unplugging the USB cable and see which one disappears. Use this COM port number in the opening dialog of TeraTerm serial connection.

Re: QMX+: quick exit from menu system?

 

I second that. I have several times tried to transmit after having checked SWR, only to discover that the QMX display still says "Tune SWR" or "Hardware tests" - and nothing is sent.

Very simple QMX software request

 

In operating the QMX+ with a non-resonant antenna and a manual tuner, it is unavoidable not to get the 'S' in the display to the right of the frequency from time to time. The 'S' just looks like some feature which has been turned on, but one quickly learns that it is an error message since the transmitter has shut down due to high SWR. By the way this is a very nice feature compared to e.g. the QDX and it has probably saved a lot of BS170's already.
?
But my wish is that the 'S' could be made more visible - for instance that it would blink on and off - thus alerting the operator that something is wrong.

Re: QMX+ Strange Audio Artifact - Help, Please...

 

Jeff - you meant C504, right? Not C604?? :-)
?
I can handle replacing C504 and D502, I'm pretty sure. Looks like I can get a C504 from Mouser for $0.29 providing I have the right part number (512-SS14), plus shipping - ughhh. If that's not the right part number, please let me know. As far as the tantalum capacitor C504, not sure about a Mouser part number on that one. If you have a number then I could get both from the same supplier and save a bit on shipping.

Well I just had to request one of these. ?I appreciate you printing the cases and locating the parts for ones that do not have printers. ?That has always been my nemesis of not having many useful cool plastic ham thingy's.? ?
