I have to smile when I keep seeing requests for more power, surely the answer is in the name, “QRP Labs”. Notwithstanding the 10W and 50W add on amplifiers, surely the radios themselves should

I've had some discussions with Hans about what it would take to produce a very useful user-friendly digital communications "appliance" based on the QMX. I think that one way to implement this would

https://www.youtube.com/watch?v=QqMDmRqCZDI&t=3s This reminds me of what I did with my QCX.? If I had a top case with correct size hole for the display it would look professional, as is I have to

Hi Jack et al Thanks OM, encouraging comments :-) I wouldn't be too concerned about Hans workload. Think about it. He has Gross underestimate :-) To be strictly accurate: 21,343 QCX-series (QCX,

Hello Marek, please read my post from a different thread. /g/QRPLabs/message/142910 Maybe there is a medium value resistance between neighbour pins. If you put voltage at this place

Sorry, typo!!! Correct is 2 - 3, 3 - 4, ..., 14 - 15.

Jim, so something was wrong in this area. Maybe you fixed not all. A missing connection is bad and also some unwanted connection between pins. Such an unwanted connection between neighbour pins may

Maybe the reason he blew up the BS170s during calibration is because Q507 was dead already. Tony AD0VC

Steve, I'm not sure about the BS170 but 99% sure Q507 is dead (only some silicon wire). Yes, a broken BS170 could affect Q507. There is a small possibility some parts to drive Q507 are broken but

I’m fairly certain all the pins are soldered on both sides. My question is why the display is “corrupted”. Processor must be working to some extent. Thanks for the response. Jim w0nkn

I wouldn't be too concerned about Hans workload. Think about it. He has over 10,000 QCX-and-family radios out there and they all work "right out of the box". This includes the "standard" QCX, the

With appropriate STM32F firmware, Hans need no further involvement in developing that RPi-Zero+Display. Something interested forum members could do. Hans could concentrate on making the QMX

If you're trying to get the under 5 W bonus in a contest and you know you're running 6 W that's at least an ethical problem. I solved the "12 V" LiFePO problem with an adjustable regulator. My QMX

zBitx current on receive is 300mA, so I tend to agree with you, Jerry. OTOH, the QMX is my preference for portable work due to it's smaller form factor compared to the QMX+. I'd be concerned about

Samantha, For portable use, doing everything through the front panel and and the small display there keeps power requirements low. May be possible to do all you want by adding an RPi-Zero and a

Bruce, my QMX arrived a few months ago into Connecticut via DHL without any brokerage fee.? I wonder if this falls under De Minimis (no tariff) which may mean no brokerage required either.? From

I am in the USA and ordered a QMX+ last week thinking it would come from MO.? It was shipped from turkey.? Now I am really worried as I have heard Fedex charges really outrageous (like $75)

Good luck with that!

Jim, It can be done before mounting the display board to the front panel. That's what I did. Doing so requires a little thought and a couple of extra assembly/ disassembly to make sure everything will

Just by way of update, I received the power bank yesterday. I hooked up my QMX to it using the USB-C to DC cable and voltage meter items I purchased and linked above, and also a 60w dummy load just to
