Thank you Hans, for implementing CAT data transfers for the older QCX models. I enjoy QRP contesting and this allows the QCX to play nice with the N1MM+ contest logger. I added the hardware needed to

I completed the assembly of my mini and was able to tune it up with no problems. I operated the mini for many hours on FSKCW and it works well in that mode. The issue I have is a higher current draw t

Just finished my QCX-Mini. It appears to be working well. One odd thing is anytime I change frequency using the tuning encoder I get this sort of low level crackling noise, sort of like an old dirty p

Firstly both my rigs, QCX40 and QCX20 mini are working superbly. I built the QCX40 over 2 years ago and it resides in an enclosure very similar to the QCX+. I have permanently wired both units so that

Hans, If there is already an RF power meter in the QCX, would it be feasible to turn the RF power meter into an SWR indicator? Many QRPers already build a TinySWR into their radios...: https://ae5x.bl

Built my 40M QCX Mini yesterday afternoon and completed alignment and power tweaking with no problems. Getting 3.7 watts from questionable 8 cell AA battery pack and 5.3 watts from my bench 13.8v supp

Hi Guys, My name is Fabio from Brazil. I finished the assembly of my QCX + 40m, to my surprise there is no signal of transmission or reception, I was very careful when winding the coils and the contin

Hi all, is it possible in some way to connect the telegraph key to the ULTIMATE 3S, in order to use, not as a beacon, but as a CW telegraph transmitter?

Finally found time to get back to the bench and having checked T1 I find no faults. Next I have carried out the voltage checks in trouble shooting guide. I have set my supply close to 12v as Hans does

Hi all, received today my pack of ordered tantalum capacitors for the C38 to protect my QCXmini. Interesting - Philips bonds the '+' to the cover ??? Am I right ? 73's de OE1MWW Wolfgang

Hi all, The QCXmini or QCX+ for the CW illiterate ? Why not! just built on demand a simple setup for 'full computer CW' with a QCX+ The little interface is on top of a USB to TTL type CP2102 circuit (

Will be on with the newly built QCX + on 80m and the Mini on 60m. 73 Ian G4GIR

Just completed my QCX20mini, what a fabulous little marvel! Instructions spot on and I didn't put a foot wrong (a first). The alignment was straightforward and stations came piling in as soon as I con

There was a thread a while ago about folks now contemplating oscilloscope purchases. Alan Wolke, W2AEW, has a number of really good YouTube videos ON MANY SUBJECTS but this one might be of interest to

Hello All, I’ve just completed the Ultimate3S (with the GPS receiver kit QLG1) and I’m delighted. I’m currently transmitting at about 300mW on 10, 15, 20, 30, 40 and 80m and I’ve had spots as far as N

Hi Everyone, I would like to share my experience with the new QCX mini. I have assembled the kit and adjusted everything as per manual without any problems. After some tweaking with toroids I got 4.5W

Hello, Thanks for approving my request. I have finished to build the CQX+ and, despite the fact I did check it several times, IC9 was in the wrong way and it popped :-(. I have ordered a a new one and

Hi Hoping someone can help. I built my QCX plus a while back and it has never worked. I just get the single line of blocks on the LCD. I have traced from IC2 to its connected components and everything

Greetings all and Happy New Year; Just want to know if anyone has had success in doing a framework update using a Raspberry Pi instead of an Arduino UNO. If so can you share the details? 73; Kurt - W2

I have linked the RF test pin to my RF (BNC) output. When I go to the menu item 9.1 Voltage it reads 14.5V while I am transmitting, good so far, but in normal operating mode, I have the battery icon d
