John, I'm not sure what this means? A Rev 4 PCB, or the 1.04 firmware? Either way, you need to use a terminal program to go into the QDX settings and change the audio levels there if everything else

By doing this you recharge the pack with storage function and will have only 3.85 volts per cell at the end of the charge for a total of 11.55 volts. Another my hobby is rc airmodell and normally put

Bruce, what GPS board do you mean? The QLG2? 73 - Pierre - FK8IH

Ok, thanks, so Edison thought of Polar Modulation. But in a sense which is very far away from SSB implemented by pilar Modulation. -- Sverre LA3ZA http://la3za.blogspot.com

Hello everyone, I inform the group that Hans and his staff are following my problem providing a solution that will solve it permanently. Thanks Hans.

I bought this device from Amazon: DollaTek ZK-4KX CNC DC Buck Boost Converter CC CV 0.5-30V 4A Power Module Adjustable Regulated Cost ?12.99 in the UK, It's probably better to search for that

Built in GPS. Switch On for Cal /WSPR/ Digi/ beacon. Off otherwise Audio/ Speaker Additional cooling and power supply tweaks a few other things

The GPS board will fit nicely inside the standard QCX case although you will need to do some careful measuring and drilling. You also need to add a switch on the two data lines (low current gold

Ken, I don't have a QMX, I have a QCX+ and the only GPS I could run is the QLG2. 73 - Pierre - FK8IH

Sri my english - not rf choke, coaxial choke, current balun. hi

Test a rf choke near the antenna side of your coax. This solved same problem with my portable groundplane.

Hi. The QMX must be in WSPR beacon mode. Philip g7jur

What he was trying to describe is this: Some QMX units, immediately after installing the new firmware, fail to automatically restart into normal operations mode.? They remain unresponsive until you

What do you mean by this? The radio doesn't start at all, so it is hard to power down. Tried powering up with pressing button and connecting power plug, nothing - no signs of life except the pop at

Check the cables. instead the antenna, connect the dummyload behind all your cables and tuner.

Pierre, why go to all the extra cost when you could just fit a QLG3 module within the QMX+ and use the external GPS antenna? You can display GPS information on the QMX screen. 73 Ken G4apb

Perhaps you downloaded ver 0.93 instead of ver 0.93a of the app. You are describing the prior app behavior. Stan KC7XE

I watched this video and downloaded and set up the software.? The software communicates with my QMX as it is able to set the frequency.? However when I press "SYNC TIME" my QMX clock display area
