It looks like Hans inadvertently sent you one of the components from his upcoming kit: -- John AE5X https://ae5x.blogspot.com

Good morning. Although my QCX+ 40M is running fine, it only takes one (old man) screw up to cook the finals in almost any radio. Looking ahead here, and hoping I'll never need to proceed.....if I do

Mike, JP17 in the mini is the 4 pin male header at the back edge of the main PCB. It is for the on-board RF Power Meter (pin 2) and the on-board DVM (pin 2). Pin 1 is +12V and pin 4 is GND. If you

A good home build learning experience build would be: https://www.k8iqy.com/qrprigs/2n240+/2n240+page.html There is a lot of info on how everything works. It was a very popular project in the qrp

I got my novice license in 1981. Same first rig! 40 meter dipole made of used house wiring pulled from a friends defunct chicken house! 73s John N4HNO

Someone on here mentioned the use of slightly long pieces of heat shrink tubing to avoid accidentally scraping off enamel while making the binocular transformer for the QDX. The manual says to gently

Allison The user might think of the EFHW transformer as “a tuner”. My experience with a 1:49 transformer fed half wave antenna is that there is some residual SWR that can be easily matched with

You are very welcome. You may want to file it back if you are putting it in the cute QDX case, as it otherwise will exert strain on the ground solder joint, which could fail, and then in turn cause

Many thanks Dave for the photo posted of your powermod to the QDX v1 which inspired me to find a 78M05 and fit it to my QDX for the same reasons. Fitting was a bit tricky mostly to get the tab

Tom, M7MCQ Your using a EFHW and a tuner (antenna matching unit)... So let me get this straight you have a tuner and then another tuner at the antenna? I'm puzzeled by that. If the EFHW was reasonably

kc0gkf, Why isn't the SWR perfect? I presume you means not 1:1 as anything below 1.5:1 is fine. For a given band the SWF should easily be below 1.5:1 unless the wire part of the antenna is too long

I well remember the blind panic as my first HF CQ call on CW was answered, though the logbook is not available to me right now in this qth. It must have been about 1982 or thereabouts, and I was using

Steve, 2N7002 may work well as Q4 but it has a higher turn-on Vgs threshold than BSS123. From Onsemi data sheets: BSS123: VGS(th) = max 2V at VDS = 2V for 1mA drain current

One of my first contacts as a newly licensed amateur was 51 years ago and it was G3UFR/M. It was a CW contact! I did not understand the cw “/“ so I have his call sign logged as G3UFRSTROKEMOBILE.

Hi Lawrence I'm curious as to why they aren't a good fit. I checked your order and it is the QLG2-SE you have. Not the older QLG1. So the QLG2-SE has a 80 x 37mm board and is designed to fit right

And yes, to be absolutely crystal clear, that picture is of JP17 :-) -- Julian, N4JO.

Hi Mike If you watch my YouTube video on the QCX-mini https://www.youtube.com/watch?v=VET_JgxCwxw you will see that I start off with an assembled mini then I take it apart to show you the insides. It

Hi Mike, Yes, that tiny little thing shocked me too when I first saw it! Here's a picture of an installed battery monitor jumper. As you can see, it's on the north side of the main board, right above

QDX R2 arrived yesterday. Put the thru hole components in Monday evening and coils this afternoon. Fired it up tonight with old laptop, but W10. Initially would not play with ancient version of
