Shipping to Europe is very expensive for me. I handle it on a case by case basis, if you are willing to pay the shipping cost (which is more than the assembled mic) then we can work something out.

Can anyone give me a direct URL for the latest QCX+ mega328 firmware? I found a link to the T1_08.zip file through this board but not seeing a link to the latest (1.09a ?) TIA. Charles.

Very nice! TNX. Your English is excellent and so is the design. I am using a 4States Group QRP Tuner inside a QMX+ case, because it tunes a random wire. It also works well with a short whip and

Stan WSJT-x (actually hamlib) does not use the mode commands correctly for QMX, and for some reason sends a 'lower-sideband digital' code to QMX if you set the mode to "Data/Pkt" That explains what

Hans is likely to get a big head with all that praise.? I'm sure most of it is due to that "under the roof dipole."? :)? :) Seriously though, it is a remarkable radio. While I'm way down in the

Steve, The ProgRock2 is a tiny square wave generator (Si5351a) -- it replaces the entire oscillator circuit -- you don't use it in a Colpitts oscillator, you replace the oscillator with the

Hi anyone, I would like to learn more about weak signal modes? Please suggest a good book for beginners. TNX, George K3GK

Chris, That's a great design!? I've been thinking about making something similar, but I hadn't thought of the speaker. Have you thought about writing this up for a QRP Quarterly article? 73, Mike,

Hi, yes it works now. Changed Device Parameters in registry as well (EnhancedPowerManagementEnabled) and switched the QMX In Firmware update mode.. Sometimes its good to ask, when you don't see the

Hans, Would it be possible that when an external microphone is plugged into the paddle socket that SSB:Input be automatically set to "Ext. Mic" and that if there is no external microphone plugged in

Hi everyone, I've been using my QMX for about an year with great joy and happiness when suddenly my QMX stopped receiving or transmitting. I'm fairly new to radio and i am struggling to find the

Hello, at the moment i can't see your email (difficulties with created account there) on qrz.com. And i see two Erik Larsons there. What about sending such microphones to Europe?

I am not 100% in the know, but I saw a few videos that after updating firmware, they did a factory reset and they had to choose the bands their radio was made for. I cannot advise if this is

Hi Michael, there is already a thread covering this ….. QMX+ with ~1000 tone on 12M & 6M I did sent it to Hans direct some time ago but so far no response. I also see the poor sensitivity on 6m.

Hello, I recently build QMX+ and noticed a huge noise floor and wistling a 6 m. Therfore I measured sensitifity using a signal generator. Band [MHz] Sens [dBm]@Noise+10dB Noise [dB] 1,85 -100,0 0 3,65
