Hello, two questions: 1. is power limit regulation for CW and digi foreseen in future releases of firmware? I have a transverter which, unfortunately, can accept maximum input power of 100 mW. I

Is there a block diagram of the QMX? I am doing some troubleshooting and find that I get a bit lost in the detail of the schematic. Thanks, George, N9DXP

Nate this was a great diagnostic tip! It was definitely the LPF. I desoldered them, rewound and reinstalled - but now get nothing on 15/17. The troubleshooting continues... [email protected]>

Hi Alan, thanks for pointing this out! Somehow I always thought QDX had the same 12kHz offset just like QMX, so when queried by N1MM, the DLL returned its LO frequency with an offset of -12k. Now I

Hi Martin, I'm in Hummelsbüttel. No callsign yet, I'm still in SWL mode. Just passed the class A exam last week and I'm now waiting for the Bundesnetzagentur to assign the callsign.

Yes. The module has GND, VCC, RX and TX exposed on a pin header. RX is not used in this application. TX is connected to either ring or sleeve (not sure at the moment, consult with QMX docs), GND is

Torsten, As it is the antenna that does the sensing all that is required is to match an antenna system to a suitable receiver. The QDX/QMX Labs receivers are suitable. 73 Alan G4ZFQ

I plan to use a Retevis HK008 ( https://www.retevis.com/2pin-mic-active-speaker ) - active speaker/mic. They need rewiring for the QMX / truSDX (yes, same pinout)...but they do seem to on a very good

Good morning list :) yesterday evening one question came up when talking about ARDF: can the QMX be used as an ARDF-receiver? Cheers, Torsten -- vy 73 de Torsten | DB2TE /"\ ASCII Ribbon

Thank you. I spent a few hours tonight going back and forth from Digi to CW. It was very noisy on 20, and there was some fading too. The cw filter is one world and the Digi world another. The CW

I can see I just missed it yesterday...

Hello George The filters are software defined in the firmware, not hardware defined. So I suppose the CPU capacity becomes the question, and not one I know the answer to. Yes, the decoder wouldn't

You can get them in packs of 10 or 20 from Aliexpress. [email protected]> wrote:

Should be the same as trusdx, I have a k6ark mic I am planning to use with mine.

Does anyone know of a commercially available mic with PTT button that is wired correctly for the 3.5mm mic input on the QMX/QMX+? Looking at the QMX assembly manual, I’m thinking the pinout might

In going through NA5Y's QRP-Labs 50 watt amplifier trouble shouting guide and doing all the voltage measurements both on receive and transmit I found a discrepancy at the very last test point on the

I have always had the same issue with my QMX. ?I’m happens on “Fake It” and “Rig”. ?So just stopped using split and everything seems to work OK. ?But it would be nice to have it working

super helpful, thank you! Did you connect the USB power ground and the ground (sleeve) on the 3.5mm TRS plug together?

Thanks, Ron ... tomorrow's little soldering project. And then on to reprogramming my Ethernet-based signal generator to use the Si5351a, rather than the AD9850. Cheers - Bruce K1FFX
