Found these on Amazon. Intended to be used in pairs on laptops. Now I have one for my 20 and one for 40 meter Minis. W3PYF

Chronic? That depends, normal if you do not power cycle the QDX. 73 Alan G4ZFQ

Hello Mike Just building a 40m QCX mini.? Fitted T1 this morning along with LPF components out of sequence to ensure I could check out the completed filter before doing anything else,?having

Anyone seen this in Win10?? Chronic failure on USB being plugged in.

Hello all, As the mains ground system is heavily poluted by all kinds of noise, I have always been using a separate radio ground in the garden. Especially using any kind of end-fed antenna, this will

Wonderful, Hans...thank you ! Of course, I want my new assembled 20, 17, 15 ,12, 11, 10m QDX built & tested for 12 volts. I don't mind a few dB less power when I operate the QDX at 9 volts max ! 72 /

My 1300Z session: I started on 30m with a?nice QSO with SOTA station DL20SOTA, operated by Mario DJ2MX. He was using a (tru)SDX with 4W into a linked dipole, and came in with 579. I used my 20m QCX

Yes, many theories and some good some bad (lot's only half explained). Example, ground loops: https://www.para.org.ph/para-Grounding-Systems.html The point them out and mention a 'single point

<hijack> It'd be really cool to make that same jack into a "key" jack for CW, in other words, key the txcvr on it's current frequency. Plug in a keyer/key and go to work. </hijack> -- Mitch, AB4MW

Thanks Donald, Dennis - exactly what I needed! :) 73 Terry

Bryan, Actually, it does cost something: time and convenience. -- 73, Dan? NM3A

I have had two lightening related failures over the years. Both were due to induces currents from nearby but not direct strikes. One was a TNC II (from TAPR) in the 80's. From the failed parts, it

Will do all. I will probably create another group on groups.io so we don't inundate the main QRPLabs list with emails. I'll post here when that is accomplished. -- Mitch, AB4MW Sent with [Proton

The only lightning protection system that works for me actually costs nothing. Disconnect. That includes disconnecting from grounds as well. Don't ask me how I know,... twice. Rf grounds are a

I have a (cheap) USB cable that recognizes my cell phone and my programmer (in Windows), but the data transfer only works with the mouse or keyboard. 73 Reiner

Just to add one other idea to the mix, have you tried a different USB cable? Although they are fairly reliable, I have had at least two where the wires have fractured internally. 73, Alan, M0PUB

Mike, This is ham radio. Build the kit any way you desire and for any reason. Do tell us of your success or failure please. I teach all new hams that we learn more from our failures (and others

Mike, I did that for the LPF's, see my blog https://on7dq.blogspot.com/2020/12/some-notes-on-qcx-mini.html Note that I built an older version, and used manual V 1.05, so things may be different for

Andrew, Have you tried all available USB ports? A hub? Another computer? It is unlikely to be a fault in the QDX but it will help to be sure of that. Note that all you need to do is look at Device
