I have a signal generator in a cabinet. My QTH is Connecticut, USA. The display works. The LPF kit works: the relays and LPFs test fine with my NanoVNA. And the output of the synthesizer is good (3.5V

So can I build my kit for just 1 band. I noticed that single band kits were never really available. I'm a first time builder and fewer windings etc might be nice... 40M

I understand that Hans has combined all the Q-models pre-built orders into one list, available to view on the web, but perhaps I missed something about the status of kit ordering. Just wondering what

For those that have built and got their QMX up and running....where did you find the info regarding the menu structure and the parameters within? Nothing mentioned in the assembly manual regarding thi

I’ve been told that more caffeine equates to quicker firmware releases….let’s give Hans a helping hand in this! Link below will give him an extra boost (or two) Seriously Hans, the QMX is quite a snaz

Good morning all, Just received my qrp mini, super stoked to get it out in the field. I am using a homebrew dipole antenna and can't seem to hear anything except some very faint cw on 14.100. I have m

5 years after being back in AR, I have finally installed a very stealth, inverted and sloping L end fed antenna which is tuned with just under 20 metres of wire. The apex is held by a fibreglass banne

Hi, While awaiting for my QMX kit to arrive I have been reading the assembly manual and schematics. Being in VK land we do not have access to 60m and given defence interest and existing use of the ban

What are most using to power their QDX with. My sheet says power source 12v. My 35 amp Astron shows 13.8 and I believe that is too much. My QDX was prebuilt. Thought I’d check. Thanks Stephen Stephen

Hi all, I finally got a chance to solder my QMX that I picked up at Dayton. Unfortunately there are a few things that seem to be wrong on mine: 1. The receive consumption is much higher than expected;

Sometimes slippery little capacitors are packed really tightly together and are very difficult to hold for removal. This has worked for me. 1. Tie a slip knot noose in a 8 inch piece of dental floss (

I am running the 20m version of the QCX+ without a GPS unit. I am trying to set it up to beacon in WSPR mode but it never seems to go to transmit mode. I have followed the instructions in the Operatin

I've built three QDX units so far and they all work fine, but now I've hit a snag on #4. Rev 3a PCB, I removed the short at the very beginning of the build. Built for 9 Volts. Power-on with a 7.5 Volt

I finally got my [pre-assembled] QCX-mini CW 40m on the air (don't ask) and even though I was able to make a local contact, the operation was hampered by very noisy headset connection (Heil Pro70). Ha

For portable operation I made a simple supply using a "DC DC Buck Boost Converter" and a Ryobi 18v battery. I have all Ryobi tools so the batteries are no problem. The converter is easily adjustable t

I built 2 of the 10A Power Amplifiers and in testing I managed to fry both of them. For testing I connected the input to an RF signal generator (BK-Precision E-200D) and the output to a 50Ω resistor.

Hello, Does anyone know the part number I could use to find the right 47uH axial inductors used in the QMX? I need to get a few more. The ones I was able to buy from Amazon turned out to be too large.

"tune" shows OK on WSJT-X Slow pulsing of LED on QDX when transmitting WSJT-X shows my signals when transmitting Signals are received on other receiver in shack Antenna is resonant (MFJ base loaded wh

I did comparison BPF scans of my QMX (rev 1) with my QDX (rev 2, f/w 1.4). QDX scans look good, QMX okay on 80, 60, 40, & 30m, but poor on 20m. Readings pretty much match my CW estimates of sensitivit

No one is receiving me on FT8. Transmit seems to be working: signal OK on WSJT-X "Tune"
