While I await delivery of my factory-built QMX (~110 on the wait list) I am wondering what the max current consumption might be? I've got a 10,000 mAh? 5 volt USB "brick", and I'm considering using a

Jerry, you should be able to setup 6 meters in the band configuration screen. 73 Evan AC9TU

LIN_REG_EN doesn't start at 12 V, it's staying at 0.7 volts, so the 3.3 V rail never gets power and the uP never starts. Pull up is working, no short to ground, on this line. See

Kees, I believe 470uF 10 V tantalums are also available in 7343, but are 1mm higher. -- 73, Dan? NM3A

Assuming that the hardware can work at 50 MHz, how will you change the software to enable 6 m frequencies?

Does the waterfall change if you disconnect the antenna? Are you receiving anything or just dead? Reboot the computer? Good luck, Mike N0QBH

sorry 9 for sure.? only have a 10mhz scope but the voltages on pcm1804 when splash screen is on are ok on pin17 and 18 but nill on 15 and 16.just checking this out now

Thank you for bringing up this topic so recently. I helped me in troubleshooting once I found my fried D101. The replacement on Amazon for me is 2 days, but its a good interim fix with the delay on

If you are really using 8, you should be using version 9,? Version 8 was quickly replaced due to issues.

*Thanks for your help. Will read hans link shortly, but yes i see 2 files one eprom and other ver8? software, but yes that happens every time there are 2 files and it lets me over write them*

Mike, check out this message from Hans /g/QRPLabs/message/105756, the firmware is not in eeprom but he does have some suggestions on where to look for this problem, maybe L402 47uH

Hans, I can add one tips: When installing the input power connector, push it towards the board edge. This will increase the very small clearance to the left encoder on the control board. Nevertheless

When you connect to the pc to load the firmware ( now for the nth time) do you see two files already in the QMX ? The system should only go into firmware load mode automatically the first time, then

Dr. Pedro, Once a feature is introduced, it is in all subsequent releases unless Hans notes that it has been removed or changed.? Also, all QDX firmware can be used on any board revision.? I always

I wonder what problem increasing the voltage and potential current draw would solve. Don't know what the problem is but not sure that getting a bigger hammer will help. Chris, G5CTH

Does anyone have a scope plot of what the first second of Voltage looks like across C107 when you power ON , do it multiple times ON-OFF, ON-OFF, etc. 470uF 6.3V Tantalums may only be available with

Excellent video, Hans! 73, Randy, KS4L

Hi and thanks for help. Because there is no short or high current drain i increased votage to 12v and 2 amps current. with no change.(also used my kx2 11.1v battery pack) i have reloaded software many

Thank you Ton and Evan. Yes, I noticed it has been introduced in version 1.04 so I'm using it then. 73 de Pedro, LU7DZ

Hans has a good picture of the USB-C connector in the video he just posted https://youtu.be/pBZ_SXO-LlM ( https://youtu.be/pBZ_SXO-LlM ) and it clearly shows the the solder wicking between the 16 pins
