I just completed the build for my new QMX+ , rev 1, firmware .27. The QMX + is a fantastic transceiver. I am really impressed. Hans has done a wonderful design. I was tuning across low end of 40 meter

I don't know for sure as when I do portable activations, I don't carry with me a computer... Nevertheless, I know for sure firstly that if you adress a JS8Call message to APRSIS (JS8 message starting

I found a nice narrow band external signal from some nearby device like a power supply to compare between the filter options. I looked at the IQ output and there really doesn't seem to be much

While I've not had a chance to try it yet it would seem that RTTY should work just fine.? Its one of two single tones and a Arduino can easily decode them.? Add to that its a conversational

Hi Now I prefer to use QMX+ LPFs and BPFs I used the 6m setup from QMX+ on QDX-M worked beautifully 73 DE muhsin TA1MHS

Hi Hans, This link covers spotting SOTA via APRS, APRS2SOTA FAQ (sotaspots.co.uk) ( https://www.sotaspots.co.uk/FAQ.php ) Another option is Sotamat, SOTAmāt – Summits-On-The-Air, Automāted

An alternative would be to substitute a socket head cap screw (which I prefer in general, Philips heads are designed to "cam-out"!) or similar fastener with a smaller head or file down the existing

I agree, muhsin, and I'm very pleased to find that KW3KW is still making videos! IIRC, several months ago he announced in a video that he was fighting health problems and he didn't know how long he

Hello Hans, Note 2: 15 MHz by the default Band Configuration table set up, is in the 17m band not 20m band. I didn't know that. I'll try it. Thanks

For those of you encountering issues with QMX+ rigs, please include which version you have, Rev1 (separate SMPS boards) or Rev2 (SMPS regulators integrated on the main board). Some troubleshooting

Hello Yannig I think this would be quite feasible and not particularly more difficult than the APRS message for map tracking. If you know what the right APRS sentence for self-spotting is? Any info

1st make sure Vdd and Vcc at JP105 are not shorted to ground. 2nd make sure you have 12v on JP105 while pressing the power button. 3rd then look to see if you also have 12V at input pin to IC101 (3.3v

Eddie, I agree that repairing the SMPSs is probably not a good idea. My first QMX (rev 1) kit failed with an exploding tantalum cap on the 5V SMPS. Initial tests on the repaired unit looked good and

That would be fantastic Hans... I think this would be a really cool addition to the QMX, and once the most important things are sorted, I would also be keen to see this improvement. While you are at

I just finished building my QMX+ and had the same problem. I found that I did not set the VBAT to Vdd jumper wire close enough to the board under the GPS board and it shorted out the Vdd to the SMA

How is the time set with the RTC? Don W6CZ

Excellent.I'd personally not try to repair that SMPS for possible use except for rework practice and then run the standalone tests to see if I succeeded. Greg Yahoo Mail: Search, Organize, Conquer

Yes. Works fine with the spare, I'm already on-air with FT-8 :-) 73 Dirk? - DK7CVD

So, did you install the spare and is the unit OK? GREG KI4NVX? Yahoo Mail: Search, Organize, Conquer On Thu, Oct 3, 2024 at 11:13 AM, Dirk<marvin@...> wrote: Finished my QMX+ today
