Dear all, I have finish :-) tested, and the QDX works OK, Regards, Ed G8BQR

For my first QCX I didn't have to change any windings, but for my QCX mini 20m, I had to add 3 turns to T1. Its working great, though.

So, that about wraps it up :-) Glad to hear you got it nailed down! Having some WW wire is a big help repairing traces! I've got a spool of it left over from a project I built for my son, close to 30

Jason, all you may need to do is just watch the video Hans recently put out showing how to tune up the 30 meter LPF https://youtu.be/eN7wER05T-c It doesn't really matter if you can wind those things s

Hi, I already searched the messages, but couldn't find out if this was already discussed. With the QCX+, when installing T1 I noticed the following in the manual: Page 22, step 8: "start of your windi

Wow that makes mine look really bad. Nice work!

To answer my own last question: Now, I know what I need to do.

#qcx #t1 #80m

Consult the schematic... its a good arbiter! Yes the 38 turn (for 40M) coil and the input 5 turn (also for 40m) coil end up with one end grounded the other two are not grounded and show high resistanc

Hi All, T1: Regarding my previous posting on the winding of T1 using a FT37-43 instead of the T50, one may ask what advantages were gained by changing the original winding scheme and the BPF being mad

You can also sharpen a dowel in a pencil sharpener to assist with the winding.

Thanks for working that out. Ryan KE7RW

I finally got it working and aligned. And I've just had my first QSO with it. Conditions seem to be pretty bad but I got a 599 from Belgium. So my problems were: 1. Enamel not fully burned off on one

Al, I do not know about the reading but the trimmer is where you need it. Neither fully meshed or fully open, anywhere in between is good. Probably not although you might want to do it to make it look

OK so just by way of closing this out...I went over the rig with a fine tooth comb today. I really couldn't find any problems. I did retouch most of the solder joints just to be sure everything was ma

Yes, please let us know how PLA works out. I don't remember the material of the old ones, maybe handmade of bakelite or plexiglas, and for larger sizes than T37. 73, Greg WA7IRW

Hello Hans, No, I think he's typing "Dear Santa, please send daddy a set of cable tidies for Christmas, and remind him I am getting old enough to meet the barber soon". Bless him, what a lovely photo!
