Welcome to the group VK8FEET! This is a superb and very helpful forum. I have to ask, are you perhaps an arachnologist?!! Greetings from a cold and wet Cambridge UK 73s Ted 2E0THH

Hi Dek Slightly off topic but very interested in your findings between HP and Dell PSUs. For over a year, I have been powering my QCX 40 rig from a homebrew PSU unit which in turn is powered by a PA-1

I've just successfully upgraded to 1.02b. I couldn't find definitive instructions for my particular setup so before I forget here they are. I hope someone else gains benefit from them. The only cost w

All done, it was far easier than I imagined. Many thanks for your help. 73s Ted 2E0THH

I know this must have been asked a million times but are there definitive instructions to upgrade the firmware? I've gone square eyed looking for them and can't find any reference in the manual. I'll

Hi Geoff Ah, those are just there if I want to use it as a bench PSU for some other project. As you might expect, the same breaks out on the back of the unit and connects to the QCX with a small patch

Hi Geoff That's the headphone socket on the front. Everything else is on the back. Top left: earth Middle row: paddle and antenna Bottom row: 2 pin key input for my Czech K36 and then power on the rig

This is mine. The QCX40 is my primary rig and I designed the enclosure for static use at my home station. I spent a great deal of time thinking about the ergonomics and ensuring that permanent connect

Appreciated well off topic but fascinating how many flyers are on this forum. Somewhere I have an old switchbox morse side key with the 2 switches at the top. These were mounted on the right side of t

Hi Bob That is true and I have seen alot of pilots do that. However during my training here in the UK back in the 80's it was very frowned upon. Suddenly finding yourself diverted into controlled airs

I just used a larger knob, it works fine for me. 73s Ted 2E0THH

Hi Joe What apparatus/method are you employing to measure your power output? 73s Ted 2E0THH

Hi Hi But I'll bet it will be just as thorough! 73s Ted 2E0THH

I strongly second these comments from Reg. Like most, I had never wound a torroid in my life before the QCX40 and I just followed the instructions, 8000+ kits speaks for itself. Over the years I have

Hi Jim It is tight. here is my finished T1 before it was deployed. I used a well known technique which uses a pen or a whittled chopstick held vertically in a vice. See https://www.youtube.com/watch?v

Thanks Steve Understood, my QSX40 (as you probably saw) is also a snug fit. Greg's is the first 40 I have seen with that gauge wire. Greg, I may need new glasses but I think you have 39 on the primary

Greg, Steve & Will Just to clear up any confusion I believe Roger's kit was missing the T1 torroid core. Without knowing, he tried to wind T1 on one of the smaller LPF cores which is when the issue ca

Hi again Roger Just to back up my hypothesis of the wrong former, I found a picture of my T1 before it went into the PCB. Check out the difference between the internal circumferences, mine is on the l

Hi Roger At a guess I would say you are using the wrong core. I built the QCX40 and there are 3 smaller cores for the LPF, 2 yellow and 1 red. T1 core is also red but larger the the one for the LPF. L

Hi Phil Using a graphic package, I first of all created the oblong for the front panel and then with other oblongs and circles I laid out how I wanted the front panel to look, making sure I had allowe
