Hi all, Last month I build my first QCX (40m) and I thoroughly enjoyed it. So much that a few weeks after that I ordered an other QCX (20m) and a clock and GPS... hehe I finished building the new QCX

Need some assistance. So I signed up for a Google Cloud Platform account to get the API to make the wspr.net map work on my win 10 pc, but not sure how to proceed. Which type of api is needed to make

I want to know when the QCX transmits it's about 2 minute beacon using a simple LED circuit. Could I come off the RF pin that usually measures power out? Don

Although it looked like It Worked The First Time, it wasn't until I made a suitable jumper to measure the RF power, that I found it showed zero. I heard my signal in a nearby rcvr, but it looked like

I plugged myself in to a Kiwi receiver in Brexitminster, London,England earlier today to listen for QRSS signals (that the U3S can transmit). Picking up some strange signals, maybe coming from the Pla

I finished my QCX 40m kit yesterday. The alignment went well (I think, It's hard to know what "numbers" I was supposed to see. I finally got to the point where no further adjustment would improve anyt

amen! Recently Microsoft did a huge windows10 update without warning or permission that rendered my station useless as they decided not to support the drivers for several USB to RS232 cables I use by

Hi all In almost 2 years there have been only two minor releases mostly addressing a couple of minor bugs. Now I have put together a more major release with some new functionality, and a few more bug

Hi everyone, Here is a link to a very informative video on programming the new range of ATTiny chips. Those of you with very long memories will remember that the first QRP Labs kit used the ATTiny 13.

Many thanks Alan, you nailed it. The 1st clock was the older of the two. As you suspected, the High fuse was set at 0xD9. The newer clock had the fuse set at 0xD1. I have written the corrected fuse se

Hi all. I have a problem with my QCX where I can't find the peak BPF at all when i'm turning the trimmer capacitor. All it does is switch back and forth from 1 to 2. I have nothing connected to the an

I few weeks ago when the problem of displaying the WSPR map was under discussion, someone suggested that it was possible to enter a key from Google in the "my profile" section and asked where to find

I have recently updated the firmware in my 2 QRP-Labs Shack clocks from c1.03a to c1.03b. Both clocks accepted the new C1.03b firmware correctly. That's the good news! The bad news is that only one of

Hi all. First post although a longtime follower. Two weekends ago at a hamfest I came across a QCX rig sitting in a plastic bag on top of a printed copy of the manual. When I asked him what band the Q

My QCX 40 appears to be working generally well but there is still one problem to be overcome. When transmitting, the sidetone hammers like one might hear of a station station very close to his operati

C25 didn't make the trip across the pond and I need to order a replacement. For the 40m band C25 is a 680pF component. I think it's an MLCC cap but I don't know the voltage rating. 50Vdc, 100Vdc, 200V

Band conditions have been pretty fair today. The modfied QCX-17 runs about one watt output from 14 thru 28 MHz. From 10.1 MHz down to 3.5 Mhz , tx output drops from about 500 milliwatts to about 100 m

Hello all, I just finished my QCX 40m kit yesterday (successfully, yea!). But since my kit was ordered before the new firmware T1.01a.hex was released, I realized I should upgrade it. But I was nervou
