My First POTA With QRP-Labs QMX. I LOVE THIS THING!!

[@RLKD8DNS]

I have 2 QMX (high, and low band), and have built dozens of them for people. They’re absolutely amazing. The engineering that went into the design is impressive!!

[@thedoobie1]

For a new to building stuff ham, how hard is the build? I have no electronics experience before becoming a ham and limited soldering experience.

[@OttoDestruct]

I would STRONGLY recommend having it built for you unless you're an experienced kit builder.

[@the_mad_swimbaiter455]

I think part of the fun is buying a kit and building it. Just but a qcx mini, build that for practice, then build the qmx. I've built a bunch of qrp labs stuff and I can only tell you it isn't hard, just read the instructions then start building.

[@RLKD8DNS]

@@thedoobie1I have some very high-end JBC soldering stations, and reflow equipment. I also have an AmScope microscope that aids in the build of stuff like this. For me it’s not “hard”, but it is definitely a build more a more experienced builder. It’s worth a go though. It’s a more advanced build, but the instructions are very clearly laid out. And for the price, it’s a great learning experience.

[@cchalfantusa]

Do you offer building as a service?

[@vtsmee]

for powering my QDX, I just use a USB-C PD to barrel connector 12v cable and as long as your USB-C power source (battery, charger, etc) supports 12v PD you are good to go. Easy to charge and can be used to also power your cell phone, laptop, etc.

[@amnchode]

That's what I use for my X6100 and my USB-PD powered Mini-PC. I have a Ugreen 90Wh powerbank with dual USB-PD ports that can run a both ports simultaneously at 100W & 45W, which is more than enough for my rig and my PC. It is about the rough equivalent of a 6.5-7Ah battery and can be charge using a regular USB-PD charger, which can be valuable when on the go.... like during the commute between parks 😉

[@hamradiotube]

I bought one of those too but the battery I was going to hook it up to kept turning off. I guess there wasn't enough of a current draw for it to stay on when the radio was in RX. I do like the smaller form factor of the LiPo pack, and I got to build another battery!

[@natereik]

Same

[@MadGoat]

@@hamradiotube I have one PD battery that keeps shitting off and another that puts out 12v. Not sure if I'll return it or not, since it's good for a phone charger.

[@km6zth483]

For mac you don't need to download putty. You can just use the program already built in called Terminal.

[@hamradiotube]

You may be able to, but I am not a computer guy. Might as well be speaking Chinese. I'm sure I'll figure it out one day but unfortunately I think putting Putty on my Winblows computer might be easier. I tried terminal on my Mac with some computer guys there but we couldn't get it to work. It just didn't see the radio at all.

[@lua-nya]

​@@hamradiotube alternatively, someone who knows this stuff better could implement configuration for these in a more graphical program.

Best QMX sales person in the world! I built the QMX+ as well as most of qrp labs offerings and they all work. Another fun rig is the QDX which is digital only and headless.

[@hamradiotube]

Hopefully it doesn't put too much of a strain on their already busy work flow. Serves them right for making such an awesome product though haha! I wish them all the success in the world and hopefully get them a few more orders from this video. Now if they can just get that SSB firmware pushed out...

[@thedoobie1]

Drop an old phone in that bag running FT8CN and you don't even need the computer! Smol!! 👍🏼

[@ralphnunn3]

Welcome to the QMX club! I absolutely love mine! We must have ordered ours around the same time, because I just recently got mine. I mostly use mine for CW, but I did try WSPR, and it seemed to work great. I think you should be able to install PuTTY on your Mac. If it comes on Linux, it should come on Mac, too.

[@hamradiotube]

Thanks man. It's such a cool little bit of kit isn't it.

[@MadGoat]

Just buy a buck converter $20 for a 3 pack "Valefod 3 Pack LM2596 DC to DC Voltage Regulator" converts 4-40v volts input to 12v output, so you can keep using your bioeno or whatever battery you want.

[@pcramil]

Perfect! Time to get started on CW 😂

[@hamradiotube]

I got "started" on CW years ago. I just haven't progressed much 🤣

[@pcramil]

@hamradiotube this past July 4th, I woke up and decided, "Today is the day imma make a fool out of myself trying to activate CW." I've only made 21 SSB contacts since then, compared to 632 CW 😂

[@richkimmerling3458]

Eagley Beagaly…..still building my QMX.. Big QRP labs fan. Thanks for the video!

[@canyonjam]

So many comments about the bag (it is cool, I'll say that much). I want that ANTENNA! In particular a part list would be cool. I can't figure out the bits that you disconnect when you change bands, those tubular connectors. I can sorta figure out the rest, maybe. Great vid all around, and it definitely makes me want to buy one of those radios. A certain holiday is approaching...

[@HikingSteve]

Wow. I think I want one of those radios.

[@quantumradio]

Congrats on the CW contacts!

[@hamradiotube]

Well there's only 2 so far on this radio but thank you! I'm still not a cw operator at all but I can send, and if I'm daring enough I'll actually throw my call out. POTA contacts seem to be a good place to start as were not exchanging much info.

[@quantumradio]

@@hamradiotube Yes, POTA CW may be a good next step. The hunting exchange is simple: BK TU UR 5NN 5NN TX TX BK. The activator script is also simple: K8MRD GM UR 5NN 5NN TX TX BK, and then they copy your hunting exchange above, and reply: BK TU TX 73 DE [activator callsign]. dot dot, dot dot and as you say ""Bob's your uncle". Best of luck and 73.

[@hazer72]

usually you can use terminal on Mac instead of Putty

[@hamradiotube]

Usually, but this is me we're talking about. I am 100% not a computer guy.

[@Alex-M0OOV]

Loved the jokes, references and regional accents! Very entertaining to watch!

[@Utahforrest]

I’ve built two QMX (low and mid band) and have an assembled high band. I’ve done my builds as 9v and love the performance. The best VALUE rig on the market, by far. 73

[@brandonporter4227]

When doing POTA, always get more than the minimum number of contacts! I will say that WSTJ-X somewhat limits your ability to incorrectly copy a callsign, but I've had it happen once or twice on SSB and been saved by those one or two extra contacts I got as a buffer. If you miscounted though, those one or two could also save you. I've got a CaHR Ares (9:1) antenna, but think I want to get the Apollo (49:1) and make it a linked EFHW like this. I also have a linked dipole for 10, 20, and 40 I made using a K6ARK 100w kit. Super compact. If I could get my hands on another one of those kits, I'd probably use that instead.

[@TobotronPrime]

I have the QDX already which is tiny and I ordered one of these a few months ago. They do take a quite a while to arrive if you order a built kit (4 to 6 months) but if you compare them against eg USDX they are way better and about the same price. In all it’s worth waiting for!

​@@hamradiotubeif I was a KZbinr I'd review and shill for one 😂, keep the great content coming 73

[@thuff3207]

For the QMX on a Mac, you shoud be able to use the Terminal instead of Putty.

[@cchalfantusa]

This radio pairs very well with the KM6LYW digipi. It works natively, I think you have to set the radio as a specific Kenwood model listen in the QMX instructions. Glad to look if someone replies asking. Fun way to have everything in a tiny kit and not need your laptop. I know the screen is too small for Mike’s taste based on his FT8CN comment, but you can also use a tablet with it. The USB port on Talentcell YB1203000-USB powers a Pi Zero W2 nicely while also powering QMX/QMX+ on 12V.

[@rsimons5952]

Interesting. Fldigi component on the Digipi works with no issues?

[@cchalfantusa]

@ I used it for FT8 for sure but I didn’t use FLDIGI. If you give me a fun task to try for a FLDIGI rookie I’ll give it a whirl and report back. I just have not had a need for it but always up for a challenge.

Some hams don't like FT8, but a lot of people don't even like ham radio, so, just enjoy it as the way _you_ like.

[@bendav]

I've got the 15-60 kit! Should be building it next week. Hope it's as good as your "pro" build. Now I just have to get the antenna dialed in - I want to build one like yours with links for the different bands.

[@hamradiotube]

You are much more brave than I am, building it yourself. I'm pretty confident I could build it, but I'm not so confident I would build it correctly. 🤣

[@jerryKB2GCG]

I have 2xQDX, if you are just doing FT8 they are great and much smaller than the qmx

[@donwilbanks2226]

Dude! You gave me the POTA bug! I just acquired a FX-4C and have made a couple of contacts on it from home. I'm gathering the bits & pieces to take it out in the field.

Awesome Don! Glad to hear it. I've not used the FX-4C personally but that's a pretty sweet radio. Kevin K0KLB www.youtube.com/@hamradioqrp-k0klb uses that radio a lot and loads up some pretty interesting things on his farm to use as antennas! Jeff, K3JRZ also uses that radio a lot for his POTA activations. www.youtube.com/@K3JRZOnTheAir Hope to catch you on the POTA waves sometime!

[@jamescoffey5225]

You can also drop the 13.3 v of your 3 ah Bioenno battery by putting 2 diodes in series attached to your power cord. This will drop the voltage seen by your transceiver to 11.9 v.

[@hamradiotube]

I just used a buck converter before I built the battery. Simple enough fix.

[@jamescoffey5225]

@@hamradiotube Yes, you can, but I am a cheap Ham, a VERY CHEAP Ham. My junk box just happened to have two available diodes for such an important use! 😊

Series a couple of 10 amp silicon diodes in your power cord. Each will give you 0.7 volt drop across its PN junction.

[@NovemberOneOscarGrouch]

Can you turn down the audio in the computer settings? Cool little radio. I'd bet you could use an android device and run FT8CN for a lighter pack.

[@hazer72]

ohhhh I thought you had to actually remove sections! Definitely going to build that antenna

[@hamradiotube]

Nope. Just cut for the bands you want and link them all together. In my case I cut the first wire for 17 meters. Then added a link for 20, then 30 and then the rest of the wire after 30 gets you 40. If they are all linked you'll get 40, 20, 15, & 10, but when I want 17 or 30 I can just unplug the link and I'm resonant again. At the end of the day, it's just a 40 meter EFHW with links cut for the other bands.

[@theinsoutsofhamradio8648]

Great video thank you for sharing. Now i want to buy one lol

[@mrjikey]

Have the low band version of the QMX and it lives in my car as a ‘you never know when you want to play radio’ rig. You may have found it already, but in the settings you can have the audio turn off completely when turning the volume down. Not sure why that’s not the default setting… Enjoy! Michael - N7CCD

[@arnoldgrubbs2005]

I don't think it will be very long before you see SSB added to the QMX's! I saw a vid Hans "leaked" showing SSB transmitting from one QMX and being RX on another in the lab.

[@oobihdahboobeeboppah]

Just use a buck converter set to 11.9 volts. That's what I do with my QMX, & it works fine. About the EFHW, are you hiking some distance to get to your location, making it necessary to limit the weight of your carry pouch so you don't bring a tiny tuner? I get that, I once walked a ways to the top of Mt. Davis, PA. BUT IF YOU'RE DRIVING TO YOUR LOCATIONS, WHY ARE YOU CONCERNED ABOUT A FEW MORE OUNCES FOR A TUNER? Ditching the devotion to half wave antennas was the smartest thing I've done in over 50+ years as a ham. For portable ops I now use either a 53 or 82 foot wire along with a hand sized auto tuner to work 80-6 meters (dependingon which radio I pull from the suv). No fussing with jumpers in the air; I just work whatever band & mode I want without getting up. Piece of cake, and easier to use than a HW. Whether

[@hamradiotube]

I did use a buck converter when I first got it, but why would I want to carry another piece of gear if I could just make a battery for this radio? Much more convenient. As far as the antenna is concerned, I'm not into tuners. They can fail, you can forget a jumper coax, the battery could die, etc. etc. etc. Any problem with a tuner means you're most likely not getting on the air. With the linked EFHW's I make, they're already resonant on 40, 20, 15, and 10. Adding links for the other bands makes them more versatile, while never having to rely on a piece of equipment to make my radio happy. That's how I roll.

If you're smarter than me with computers (most people are) and can use Putty to get into the QMX, the fix takes a matter of seconds. People say I can do it from the Terminal on my Mac but that's above my pay grade. I don't know what was done other than what I mention in the video, but it had to do with adjusting the audio levels per band. He boosted them up to 65 and that seemed to work.
