Thanks Bob; I am looking for a LC meter your post about this item is a good tip!? Keep us posted on your next LC meter (review).? 73, de Karl, KO8S

Hi Andrew, I have given some thought to the heat issue, especially regarding drift although I will be using the QLG1 GPS unit. What I intend to do is drill a small hole near the end of the heatsink

Good news on the rogue solder ball find. Sounds like you are on the way now. I believe this type of issue will be causing a lot of the problems that are being posted. There is not much room for

Well I have tried everything suggested and still see nothin on the display. Maybe it is time to try selling as is to cut my losses. Of the mni kits I built this is the first one that I cud not get

Hi I built this up, but found he whole unit over heated running 3-5 Watts. My unit drew up to 1.5 Amps. So removed the 5 Watt pa, now wondering what to do next. Let me know how yours works. I might

*Hold the fort! It turned out to be a stray subatomic solder ball!* Here's the new scope screen grab: Woohoo! This is quadrature! I have a microscope for use with surface mount devices, given to me

It looks to me like the Clk0 and Clk1 outputs are shorted to each other. -Lee- WA3FIY

I've helped put together a number of QRP-labs beacons over the years, starting with the "Ultimate QRSS" beacon (not synthesized) and as such, been enjoying modifying them in various ways. After

Ok im getting home late tonight from a road trip so will post tomorrow. I have two circuits, one audio driven that is plagiarized from the BIXT group and adapted for this application...easy to add

Hi Dave, It looks like maybe CLK0 and CLK1 are shorted to each other since there appear to be three logic levels instead of just High and Low. One level when both CLK0 and CLK1 are? High, a second

Hi folks, I received my QCX 80 Mtr kit a couple weeks ago (kit no. 1536) and its now finished and undergoing tests. The only part of the kit I had some difficulty with was the transformer (T1 on the

Hi Dave Have you checked with a DVM to see if there is a short circuit between Clk0 and Clk1? It's as though they are shorted together, fighting each other. 1/4 of the cycle is flat at the top,

Hi Dave. I assume your scope triggering is set up so that you trigger off one channel and use this one trigger to trigger both channels and not trigger off each individual waveform? This is sometimes

I like the zeners idea in lieu of the LDO regulator because eliminating the LDO's voltage drop goes halfway towards eliminating of one PV cell from the array.? If there's a battery on board, one

Hi Guys, I double-checked that 3.9 is set for 40 meters, as it should be. I took extra care to have the two channels identical. 10x setting on both the scope and probes, calibrated each probe, DC

Hi Michael, Thanks for the explanation of your plans with U3S and U3B.? I think running the U3S on solar power on the ground is a great idea because you'll learn about PV the fun way.? Then you'll
