A laptop displaying software sits in the foreground, next to a portable device, with a person's feet resting on the edge of a vehicle. In the background, a rural landscape features a winding road and sparse trees under a clear sky.

A blue SUV parked in an empty lot during sunset. The sky features shades of orange, pink, and purple, with silhouetted trees in the background.

Yesterday I was able to do a QRP POTA activation at US-4160, a new park for me. I made 28 FT8/FT4 contacts, well 27 because one was a dupe. I used the QDX but need to get the QMX+ out in the field next. I am excited that one of the contacts was from Gibraltar! #qrp #qrplabs #pota #HamRadio

A QRP meter displaying a reading of 3.31 is in the foreground, with a QRP Labs QMX+ transceiver beneath it. The background includes tools and equipment typical of a workshop.

Wound for 12v PA, running 12v in and seeing ~3w out on the High Bands up to almost 6 on 160m. I get about 3-4 on the 40-20m bands. Looks good. Picking up some RF so far so good. @qrplabs QMX+ #qrp #qrplabs #HamRadio

First POTA of 2026 - Whiskey 9 Bravo Lima November So my first attempt to take out the QDX on its first POTA ended up in failure because I forgot the power cord on Tuesday Jan 6th. I was kind...

HOLY COW! With 2w and my EFHW on the QDX I just worked 9K2GR in Kuwait 🇰🇼 (Gridsquare: LL49AH / distance: 6762.4 mi) on 20m using FT8 #hamr #wavelog #qrplabs

Close-up of a printed circuit board (PCB) featuring various electronic components, including resistors and capacitors, with visible solder connections and markings.

Alright back on track after parts arrived and replaced the broken C33!

Thanks to Walt, K6OGO over at Costal Waves and Wires for the kind words about my Turret Mic which he used when reviewing the QMX+

I’m winding enamelled copper wire on the FT140-43 toroid to make an EFHW. The workspace is cluttered with various tools and materials. I’m wearing glasses and The Phantom is embroidered in purple on my T-shirt.

Made progress on the 80-10 QRP EFHW antenna over the weekend and have now planned to make a 12V PD trigger for the #QMX by #QRPLabs. Tested Rx on it with the Silicon City net on 40m, thanks to VU3JIM, you can see the short video at: tilvids.com/w/buA81p7KLs...

A black QRP Labs QMX transceiver is positioned on a wooden table, featuring knobs for volume and tuning. Behind it are two ceramic bowls with varying shades of blue paint and a woven basket in the background. A green cutting mat with measurement markings

Came home to a wonderful little package! This #QRPLabs #QMX has a nice build quality. Now onto making the PTT mic and an EFHW for it to make a nice #QRP backpack.

...already built. The #LightAPRS tracker from #QRPLabs is about perfect, but it's a hobby board.

That, in a CASE (I do not have 3D printer), with a belt clip, an on/off switch, & an emergency switch.

If the emergency switch is turned on, the beacon text changes to "Emergency" so that my screen...

Just playing with QRP labs radios today. Vertical MC-750, 3-4W and 20m got a good reach even the sun is throwing tantrums.

First time listened the QMX SSB and it sounds really nice!

I built a #QRPGuys 40-10 #Minituner a few years ago but never built a wire for it. Thanks to current #Geomagneticstorm conditions, I built a 40 -15 Meter Linked #EFHW that I can use with my #Youkits #HB1B and my #QRPlabs #QDX. #AmateurRadio #HamRadio is so much fun!

Picture of a QMX radio on a table with a microphone and notepad. An antenna is also attached to the table.

2/2

Based on the hard work of Adam, K6ARK I designed a PCB which does all the work of the connections and designed a case for it.

I think it looks like a Turret from the game Portal, hence its name.

These ingredients produced a great #FT8 / #CW #MorseCode #pota #Parksontheair meal on 40/20 meters. This activation was WELL DONE! #qrplabs #QDX #QCX #PutikeegMiniStraightkey #PutikeegKey #HamRadio

This might be unpopular opinion but I think QMX firmware is irritating to use. get it many times into a state that it just doesn't respond to most of the buttons.

Also if the SWR is exceeded, there is no error or anything showing this on screen. Hans said that there should be, but there isn't […]
