That’s awesome! We are going on Royal Caribbean in December. I think they are a hard no on ham radio but I need to investigate further.

Probably balloons. I have some recollection that I experienced the same “what’s that?” ?I do not remember where I found the answer though. 73 Mikael

There was an very small shortcut on the USB-C backside. The soldering in this prevbuild qmx is really noobish. >

I've been monitoring 10m today with my QDX on WSPR have have found some strange callsigns appearing 0F5CUR GL94 17 0S5GBG GB25 ?0 0P5IFN GL77 ?0 0T5RZB GL86 ?3 0W5RJV GL94 57 I'm guessing these

Fellows, one more small point on using a Zener in QCX... The QCX PA is designed as a Class E amplifier. As such, the tuning of its output circuit is somewhat critical to maintaining Class E

Bruce and Bryan, Both the QCX and QMX series of radios have key click filtering that reduces the end-of-transmission spike that I believe is killing most QDX BS170s. The combination of high SWR and

Bryan Curl Apr 6? ?#120489 can the 47v zener diode protection be applied to the qcx variants? Not unsurprisingly this has been queried at a few points and I think I remember someone saying they had

Hi,?I soldered in the bridge and a new drive was displayed under Kubuntu. I put the latest firmware there. After initializing the EEPROM, the QMX started normally again. I removed the bridge. Now it

Bravo, Bruce! An excellent post. JZ

“ Various semiconductor data sheets explain the leads are the primary heat sink” I’m not familiar with that manufacturer or part number ?? We are talking about a specific manufacturer

It's not my QMX. I don't know why the 1_00_017 is not on there. Windows 11 and the latest Kubuntu. But that shouldn't matter. 73, Holger DL9HDA

My QMX 12V works very fine and for hours in the field with the 9V/12V bank from TalentCell. 73, Matthias DL5MAY Matze

Mike, " All 3 legs of Q507 measure 11.5 Volts RMS in both transmit and receive states" . You probably mean 11.5V DC, but whatever... That is a problem! You need to find the reason and correct it

I am selling my QCX-mini 5 watt transceiver built for 20 meters. It was built for 12 volts. It is in its nice QrpLabs enclosure and works just fine. I am a non smoker. I will ship this via USPS to

I thought I'd post a description of my attempt at operating the QMX from a cruise ship in case anyone is interested. The XYL planned a cruise for spring break and I couldn't resist stuffing the QMX

About 2 weeks ago I finished building a high band Rev 3 QMX.? I was able to flash the firmware and almost everything worked: - I connected to WSJT-X and used the CAT functionality to change

Never had an RFI problem with even the cheap eBay buck converters. You could also use a 7809 regulator on a small heat sink. That's what I do at home from my 13.8VDC PS.

I haven't done this yet myself, but will be soon for a QDX. I'm looking at either a battery back that has a PD USB-C output, and then use a cable set up for 9V, or getting a battery pack that can put

Now that the high desert weather is finally warming up, it is time to finally power on my9 volt QMX for the first time and take it into the field for POTA. However, I can't find any mention of the

That did the trick! I reflowed all of the RF components which didn't help, then I saw your message. Sure enough a factory reset made the sweeps looks great!.?And I do have about 3.6W out on all bands
