I did the same thing, but I measured my coils with the nanoVNA before soldering them into the QCX Mini. Then I measured the LPF in situ inside the Mini, by changing the order of the construction. See

Hi All, I prefer posting on my blog, and on the SOTA Reflector, because it's easier to edit if I type a mistake. So here a summary of things I posted lately, on the QCX Mini. Enjoy, and comments invit

Tnx Hans and Al, I'll use your tips when I find some time to investigate further, it is now running at 20 minutes interval. I'm making a new blog page with my measurements on the QCX Mini now ... so Q

I'm also completelty new at this QRSS/FSKCW mode. I used the parameters by Ben PA2ST (TNX!) and it seems to work. Running the QCX Mini on 20m 14.096830 at the moment, with 1 Watt, on a groundplane ant

1900Z report This was my best session ever! I made 5 QSO's and all 5 were QCX'es, WOW. Tnx fer QSO's to G4GIR, M3PMG, G0ILN, G4OJF and G4YTJ. Note; as for calling CQ QCX , I alternate between CQ QCX,

Not much luck at 1300Z Called CQ on 20m for 30 minutes, only worked GM0EUL with a QCX Then called 30 minutes on 40m, only one reply, no QCX. Hope for more luck at 1900Z Luc ON7DQ

I'll be there! 1300Z on 20m (and if not much traffic, also 40m later) 1900Z on 40m only 0300Z zźzzzz HNY Luc ON7DQ

For Richard: see my blog for a simple and cheap solution to avoid plugging a key into the PTT jack. https://on7dq.blogspot.com/2020/12/some-notes-on-qcx-mini.html Also , I have added a few paragraphs

Fred, I added on my blog that putting a fuse in a specially made DC cable for the Mini, is just as good, and it surely is easier to replace if it ever fails, hi. You can use a regular fuse there, and

I know, several other blog posts out there already, but this is my contribution: https://on7dq.blogspot.com/2020/12/some-notes-on-qcx-mini.html I hope some of it may be useful to you. Feel free to com

Mine (a 17m model) is not ready yet, but here already a few notes that I made, use whatever you think is helpful. Before mounting C30, I jumped to the section where you wind and mount L1-L2-L3, to com

Hi Dave, check my report of building one of those ATU-100 tuners (mine came as a kit from Ali Express, I paid 28€ for it). https://on7dq.blogspot.com/2020/09/building-atu-100-n7ddc.html and here some

My 13:00Z session Only 3 QSO's, one was a QCX Will be in the 19:00Z session on 40m Glad to see 4 people on the SKED page, so for the moment I think it's a good solution. Direct link to the "QRP" secti

If you're interested, read my description of building that Chinese tuner https://on7dq.blogspot.com/2020/09/building-atu-100-n7ddc.html and some field testing I did https://on7dq.blogspot.com/2020/10/

Thanks so much Hans! But there is no hurry, so please don't spend too much time on it, and certainly not before those QCX Mini's are out of the door ... hi. Luc ON7DQ
