Thanks Hans!? Much relieved.? Excited to get this kit put together! Dave AI6VX

Hi Dave It's a mistake ;-) And also a mystery... Q202 source used to go to +12V. Now it goes to Vcc (+5V). That stub is a leftover from the 12V connection. The mystery is, why Eagle CAD didn't

Actually, there is some incompatibility with new AND old rigs. I bought it for a Xeigo G90 which I briefly owned (didn’t like at all). It didn’t work with that. So I tried it on my trusty 1982

Ultra Pico Keyer has an undocumented connection between the PIC chip and the RING of the output jack. Not an issue with radios that have a simple straight key connection, which is generally where it

Hans, I received my QMX V3 kit today and was checking out Q202's replacement.? I think I found it, but I also see this strange stub of a trace next to it.? It comes off a via but goes nowhere. Is

Thanks Hans! ?That was a very fast response! ? It’s almost like you were waiting for me to ask this question! ?Enjoy the day, and thank you for QRP Labs -- I’ve enjoyed many kits Trevor

Alan and Evan, Great info and good advice. I've got a 10 pack of SMDs coming from DigiKey now too.Have looked at a few SMD soldering videos and will give that a try first.Fortunately that cap is in a

Greg, All you need is a 0603 0.1uF from a reputable dealer. Liquid flux, a clean fine iron and suitable vision. I use ordinary x4 reading glasses.Hold it in place, (most difficult part?) A dob with

Hi Greg, Soldering an SMD component like a capacitor is relatively easy.? It would be easier for me to use an SMD than a leaded component.? I put a small dimple of solder on one of the cleaned pads

I like tio ( https://github.com/tio/tio ). Simple, works like screen. Has a neat auto-reconnect feature - if the USB-based serial device goes away because it is unplugged, tio stays running and

A long time ago (pre V3.2 documentation was 3/13/2006) , we had a group build of the PicoKeyer by N0XAS (Documentation said "Super PicoKeyer Low Power Iambic Keyer"). I built 2.? One was normal and

Good morning Group, Hoping for information and validation of a proposed repair for a problem I created while assembling my new QMX kit. I cracked SMD 0603 capacitor C513 (its in the TXBias input

Meanwhile I had the time to dismantle the radio. Again I did some continuity check direct at the terminals at the pcb. ?Although the paddle jack seems to be ok I desoldered it. But the QMX still
