L5/7/9 O.K. Alan, I?ll try. But they worked well before the crash. Each Band with full power. C34 , what happens, if this conductivity is crashed ? I can receive without Problems and I can hear the

Hello Hew Your QDX was already shipped on 28-Oct-2021 and an email notification was sent to you with the tracking number. It might have been put in your spam folder. TNT tracking code 105271325 73

Hi Chris, I am running wsjtx on a raspi 4 but to my QCX mini and use the CAT port \dev\ttyUSB0. This seems to work fine. 73/Ken g4apb

Sorry - thatt should've read Month KM6WT and Gregg W7GRM

Mine worked well to finish the alignment of my Classic QCX. David J. Wilcox’s iPad

The QRP Guys power/dummy load/SWR bridge device works well and I just used it to test my Classic QCX that I just completed. Excellent device. Dave K8WPE David J. Wilcox’s iPad

Thanks, Theo, for bringing this issue up again.? In February Hans acknowledged the matter and was going to look into it as soon as things settled down.? I've not seen or found any resolution as yet.

In Rev 2, I used through-hole inductors for those 4 and deleted the SMDs. So the SMDs don't need to be removed. Just install the wire-ended ones. Given the high demand for QDX I don't want to go

Hans, Boa, you have still 3000 SMD inductors on stock... :o) For the Rev 2 boards, do you plan to use the same SMD inductors ? And during assembly they have to be removed and replaced by the extra

I use a Raspberry Pi4 to run WSJT-X 2.5.0 with an IC-7300 and it’s fine. So I transferred the USB cable to the QDX and set up a new configuration for QDX exactly as described by Hans in the manual.

Matthias, When testing the PA I suggest powering the QDX with as low a voltage as possible, 7 volts or less, I'm not sure of the absolute minimum. Possibly as low as 5.5 volts, The regulators are

Hello Andrew You asked: "Hans, what was the original manufacture part number of the inductors you were using?" I am attaching to this post, a photograph of the SMD reel label. So that should answer

Hi Fred The 5V tolerant IO and the pull-up resistors to +5V are all a red herring. According to the BS170 datasheet, the device has a gate threshold voltage of typically 2.1V but it could be as low as

Hi all *General:* Please be patient... this is a new rig, and we have yet to accumulate collective trouble-shooting experience. I have just had a nice QSO with Earl 4Z4TJ on JS8Call, 5W QDX at both

my QDX crashed after 25 QSOs on 40m and 30m. I changed to 20m. 5W power output. Voltage of the lead Battery about 13V . Than I smelled some smoke. No Power Output anymore an two melted BS170

Hi Wolfgang, my QDX crashed after 25 QSOs on 40m and 30m. I changed to 20m. 5W power output. Voltage of the lead Battery about 13V . Than I smelled some smoke. No Power Output anymore an two melted

All, Based on the above post I went back and checked the TX line while connected to my Raspberry Pi.? I found it was now going high. I still did not have output, so checked the gates of the BS170s

Rich and the group, the KXUSB is a FTDI device which may be field reprogrammed to "invert" signals. In this case both RxD and TxD are inverted. This is how they may do a direct connection from USB to

Hi all There are a lot of points I need to make, in relation to this long thread. Long post is coming soon... 73 Hans G0UPL http://qrp-labs.com
