Hi all I wanted to make a short YouTube video about my winning 2N2222 challenge entry at FDIM... does anyone have any photos or videos of the event that they could send me? I seem to have taken only a

Good morning Hans. I emailed the support site on the web, but have received no answer. I am missing several parts for the 20M QCX+ kit. I received 6 BS170 transistors, but no MPS751. I went ahead and

Posted shipped on Tuesday May 17, 2022, Delivered to my doorstep Tuesday May 24, 2022, this afternoon, from Turkey. Doin' the happy dance, here! :) Hans, a big thanks to you & your crew! Larry KA5T Ge

So I don't have my QDX yet, but I'm eagerly anticipating and planning. I'm a POTA guy, and my primary antenna is an EFHW compromise antenna. What tuners are you using? I'm looking at the MAT-705 since

Being a newbie, I’m having trouble soldering solar cells together. Anyone have any suggestions? In the meantime I do have some PowerFilm 4.8v, 50mA panels, would this work? The Voc is over 6v. Would t

Anyone know if there is anyone down Australia or New Zealand way that has recently launched an ocean drifter transmitting on 40m? cheers Graham ve3gtc

I didn't realize the 50 watt amp is only for the QCX. I’m waiting on my QDX and can’t use the amp on a QDX. It cost me $62. I have not opened the packages. Make me an offer. Richard N6IJK

What is the least expensive and most compact/lightest implementation of a workable QDX interface to something other than a 14" laptop ? Like a 5" LCD, Rasberry Pi, and Battery Pack ? A small notebook

New to these incredible kits and the QRP LABS a learning experience. Built a clock kit with GPS and it worked so good my bride let me put it in our camper. Anyway…. Bought a U4B version 002 firmware a

Hi gang, built up a couple QLG2's when they were readily available, added the display AND a 5 volt regulator that will allow 9 to 15 volts DC input or so to operate the unit. I also 3D printed a case

Excuse me for this interruption, but since this is a QRP Labs list, I thought someone would be interested in these bits of history. For me this is a pre-SK sale.Exclusive of postage - $10 in the US. Q

This is certainly nothing groundbreaking, but I'm sure excited seeing people all over hearing my U4B just lying outside on my deck. I'm running from a 3.7 Volt LiPo and HP=1 Here, if you don't want to

My 30m QCX+ rig was up and running for a couple of months, with no problems. While connecting the power plug (after moving it's location on my bench), I inadvertently touched the dc connector (hot wit

Off to Hamvention in a few days: Ordered one of the last available. Question: I want to build it for the 630M band. That means not installing all of the great engineering Analog RF stuff that he has p

So I have a QCX, putting out 2.89 watts per the dummy load test procedure. It goes into 50W amp. Output from the amp seems low, but that is question for another thread. But given the 2.89 watt input t

The kit has arrived! Amazing less than two weeks from Turkey. Well packed and the Mug and shirt are terrific. For the first time, I feel proud to advertise someone else's company! 73 Bill

Does anyone know where I can get a replacement bulk head connector for the QCX Mini that will fit (size, spacing, etc.)? There are many out there but I don’t know the correct dimensions or manufacture

K6JTH was kind enough to send me a sample of his 3D design for a QCX-mini stand and I’m impressed. Good design combines the simple with the versatile and this is both. Hans might want to look into off

I've recently become interested in Digital Modes on 2 meters. (Trying to communicate with my son 8 miles away .. HF NVIS has been problematic). I tried to find some cheap SSB 2 meter rigs to test the

Are there any resources on communicating with external I2C sensors using the U4B? I was looking at the AHT-20 + BMP280 modules. A link to the modules I was looking at https://www.ebay.com/itm/29469114
