Greetings from Cascadia As I learn-by-doing about the many settings of my U3S, I have found that the clock loses about a half a second each time I go into the menus to set something. That's just an av

Greetings Qrp-labs fans, I wish to minimize the power consumption of my U3S as part of a project to run it on solar power. I'm using it on 2 meters. Here, the power output when setting the bias with t

Rather than stealing Arv's thread (#27567), I thought I would start a new one. Essentially, Arv pointed out that Hans' (QRP Labs) decision to protect his code for his QCX, QSX, and other projects is a

Hi all The last clock firmware release was in Dec 2015, almost 3 years ago! Quite a lot of people made requests and to prove that I really DO have a list of these, I have implemented the majority (but

Hello first little mistake made while assembling the marvelous little QCX transceiver board. I started to wind the T4 from the wrong direction but it came out nicely. When I put it on the board I see

I am unclear as to where to make a connection. The manual reads: When measuring RF power, connect the RF to be measured to pin 2 of the 3-pin DVM/RF Power connector. In this case D4 and C42 form a sim

Hi Hans Do I understand this correctly? Not only will the QSX connect to a Pi 3B+ for FT8/JS8Call modes for audio and cat control, but there will be room inside the QSX case for the Pi to reside? 73 N

Not that I'm asking for it to be included in the first release, but it would be nice to see FreeDV run natively in the QSX at some point in the future. It should run on the QSX STM32 microprocessor, U

I have a QCX on the bench with a defective 74ACT00 (IC3). I am contemplating putting in a socket to make future replacement easier, with less stress to the board during removal. What effect might that

Hi guys, I got my 6 band kit up and running last night. I started testing on 40m and I had it running for about 16 hours. I got a ton of spots throughout the day. Tonight I went to test 20m and didn’t

I just received my official enclosure and am slightly confused (pretty normal state of mind thes days by the way). If I wire the DC socket the standard way, with minus on the center pin, I'll have my

I just noticed this: * Modes: SSB, CW, AM, FM, PSK31, RTTY, WSPR beacon

after replacing the pa transistors i have a nice 2.8 w any ideas atts but the rotary encode will not work dave c

Hi all, I'm just before finishing my QRP-Labs "clock tower" and made some tests. Now i have two mysterious things: If i use a ublox M8Q GPS engine instead of the QLG1, two things happen: 1. Lat. & Lon

I just ordered and built the QCX-40 and QLG1. The QCX worked first time and I'm astounded how good it is, as were the construction details. But I can't get anything from the QLG1. The red LED is on, b

I hooked up my Qcx-40 to my 12volt supply, set it up for wisper to xmt every 8 mins. About an hour later It dawned on me i forgot to attach the antenna. Hooked it up, got spots. thought I would check9

Just announcement - my new U3s finished and running with 27dBm out (0,5W) on TopBand (1,838178MHz), ant inv-L, in JN79. As I want to see as many as possible RX reports, please tune Your WSPR monitors

Hello Hans, Happy to report that the QCX 20m #782 behaved well during last weekend's contest! Thanks for a great little performer! Enjoyed all the action. I have a question relating to the VFO kit(may

My QCX40 had been performing flawlessly, but when I just returned to it just now after an hour (on all the time from a 13-volt DC supply), I find no RF output. No smoke smell, no change in the display

I have seen 5V LCDs on ebay part no 1602A. Are they the same types as the QCX LCD which has QY-1602A on it? Dave
