You will never lose any SMD parts using the sticky PEN instead of tweezers... :) http://kitman.eprodavac.cz/adhezivni-smd-pero-stickypen-70/ (

Hans, Just tried schottky from pin 7 to 20 with 470uf tacked on to the 10uf I put there earlier, so 480uf in total at C47, and starts up fine first time. 73 Simon VK3ELH

Hello Hidehiko I do not know why your WSPR spots are different. Others have reported many WSPR reports with the QCX. I think more information would be useful. Are you using a GPS? Have you received

Hi Hans, I would just like to echo the supportive comments Martin (G0PJO) has made. I do hope you will not get disheartened by some of the whingeing comments. We need people with your knowledge and

Mike, OK, I often find myself banging my head on the wall as well! I've added the link to AVRDUDESS so time is not wasted. 73 Alan G4ZFQ

I dont mind bugs. ?Trying to work out whats causing them testing a theory and learning along the way. All part of the fun. Keep up the great work Hans. Lou, what band is your QCX? Mine is on 40m. Be

Eddie, my experience has been the opposite of yours - I find the audio quite loud on my 40m QCX. In fact, I tried using a pair of computer headphones with an inline volume control and had to reduce

Hi Daniel You probably right. My logic is that spikes/pulses can be reduced with low value caps say 0.1uF........... Larger caps say 470uF level out slow changing voltage levels but take a longer time

Hi Alan Sorry for my rantings ~ I have spent more time getting the software update to work than it took to build it. The instructions you wrote are fine (just me not reading) I was trying to run

Hi all Some people appear to have issues with their QCX not starting up at first power-up; they must switch off, then soon after switch on again, to get the microcontroller to boot up properly. I have

Mike, I got mine from here http://blog.zakkemble.co.uk/avrdudess-a-gui-for-avrdude/ and downloaded "setup-AVRDUDESS-2.4.exe" no zip. I see the zip is there, did you execute the zip and then copy the

Hello Al, First time I have read good things about SM components and static! Those critters just love to hide from you and waste your evenings searching for them ;) I call building SM boards

I agree with Martin I was a computer programmer back in the day. It’s impossible to catch every bug during testing. This is part of the reason why trading and banking systems are legacy systems. To

Having to reduce C47 to 10uF only means the problem is somewhere else, classic case of trying to compensate the symptoms I believe. I don't know where the problem lies, but more measuring is the way

Have shorted the inductors as sugested but still no luck. Cant see any placement mistakes, and hve gone back over the back with the iron again. Still no change. Could it be a problem with one of the

My version of VK5EEE's story has to with surface mount components. I'm getting more familiar with the techniques, but in one case while holding a small SMD resistor with tweezers and getting it

Keith. A nice view of the "Polar Prince" in harbour. I've followed the cruise of the vessel at times in between my trips away. It would have been interesting to have been on this restful cruise myself

Hi Hans, You seem to be getting a lot of flak at the moment. I’d just like to say that I, probably like many others, really appreciate what you’ve done. Yes I had to wait a short while for my kit.

Try SMD kits where you need tweezers to mount the parts. Fun but you lose many parts to the carpet.

I'm impressed by your 4 place accuracy in measuring the pin flight distance. I just let mine fly and then vacuum the area once a year whether it needs it or not.
