I have a clock kit finished and I am starting the build for an QLG1 GPS module I bought from a fellow ham. Question 1. Can I build the kit using the supplied antenna which mounts to the board and also

I just finished building the QDX and started checking it out. I connected it to my W10 pc (currently running Wsjtx on my TS-440S) and I set it up following the instructions. The CAT and audio connecti

In a sudden move by the FCC the use of morse code by amateur radio operators has been banned. Due to the removal of knowing morse code in the tests required to obtain amateur radio licenses many amate

Hi all Please note that due to availability constraints and high sales volume of QDX high-band (20-10m) kits, I had to change the LPF toroids to T37-17 type. Performance is essentially the same. You n

Hans, I'm guessing your team has been building and shipping quite a few factory built QDX-HBs. I was wondering if you all are encountering many suffering from low power output? Earlier your investigat

Hi, Does anyone know a good source for a QRP Power Meter, before I pull the trigger on a used WM2? My existing is HB and works fine but I saw a passing reference to a tiny one one with an OLED Display

RF output screwed up. In all the documents I've never seen a PCB layout or a circuit diagram that contains the LPF (60m) relay circuitry on the main board. The attachments show what I believe is the j

I built a QDX Hiband Rev 5 board on latest firmware and it works as expected on 20m. On all other bands output is low milliwatts on xmit is in the low red zone on the WSJT-X display on receive. It wil

What do you think ? Back home in the NRV of VA now at N4QA no slash 4. Both call signs, both signal reports, both grids .Wish I had logged this one before clearing it by switching to the FT-450 config

Just finished build the 20m amplifier. DC Connected - 16V. The green led lights up fully. but the red led also lights up but more faint. Applied 5V to T/R switch and red led lights up fully. No RF app

I love my multiple QCX rigs, but.... after having an Elecraft K3/P3 for 10+ years and now a K4D, I feel "blind" when using my QCX+ rigs - no pan adapter / display. Kind of like back in the olden days

In another thread (Raspberry Pi + QDX + JS8Call), one post (by Mario Vano AE0GL) made reference to using a tablet with VNC to connect to an RPi via the Pi's built in RNDIS Gadget support over USB. Whe

Just joined the reflector. Ordered a high band QDX as a means to get me on the digital modes - not sure how for how long, a CW QRPer for many years with my K2. Not sure when it will be arriving, shoul

My QDX showed up earlier today, and I'm trying to get CAT working on WSJT-X. Unfortunately, I'm having no luck following the 1_08 firmware operating manual. Here are the settings and error message. An
