Hi All, I got my QDX up and running today but not getting any takers at my 4.2W.? Well, I ordered a 50W Amp to use with the QDX.? It went out a few days after I ordered the QDX back on Oct 16th.?

10M LPF kit for the Ultimate 3S QRSS/WSPR TX
Hi, As this is my first QRP Labs kit I an not sure how to proceed. I started with the 10M LPF kit. After winding the inductors I decided to measure them and was surprised with the results. I am sure

Re: #toroid #20m #40m #toroid #20m #40m
The 37 refers to the diameter in inches ie. 0.37" and the 2 or 6 refers to the "mix" of the powdered iron toroid. Type 2 works best below 10MHz and Type 6 works well from 3-40 MHz. Type 7 is popular

The toroids for L1? - L4 are red and yellow and I think they are T37-2 and T37-6 types: not sure about this. I don't know the technical nomenclature or the color coding standard is for describing

Re: QDX IC7 fouls case #qdx
Alan, I hope people that have this issue don't force it cuz it could peel the IC right off the board and pads with it. All the IC's on this board are packaged in a thermal plastic and file easily with

Re: QDX IC7 fouls case #qdx
Wolfgang, Right! I have just checked the other PCB, it is the same. The design clearance is minimal, the cuts in the master board are not quite aligned so the components are off-centre. It is only

Re: QDX IC7 fouls case #qdx
Same issue with mine... Going to need to file just a bit off of IC7 package to get it to slide into the case or scoot the chip inwards ever so slightly but will likely opt to take a bit of plastic off

Re: Considering a club project kit
Mike, I like your standoff idea. It¡¯ll offer at least a little protection. I don¡¯t understand why QRP Guys doesn¡¯t add a 3D printer guy to their group and sell cases alongside their handy

Re: QDX IC7 fouls case #qdx
Yep. Same problem with mine but it will fit into one half ok and then other bit becomes the lid as it were. Not built yet but after seeing posts I chec ked. 73 Roger G4IUP.

Re: QDX IC7 fouls case #qdx
I think a photo will be necessary. I had zero issues on my QDX, which you can see in part 15 of the series linked below. Does yours not look the same as mine? https://youtu.be/GK37eBYvlp4?t=72 -- Ryan

QDX IC7 fouls case #qdx
When trying the PCB in the supplied case I find I cannot fit it. There is insufficient clearance for IC7 whatever way or case segment I try. This is the same for the two kits I have. IC6 opposite does

Re: qdx l12 inductance
Hi All Using the calculator you can also input value of series capacitor (assuming 80M=220pf,20M=22pf ) to show resonant frequency ,80m =3.73Mhz 20M=25.5 Mhz ? requires 72pf to resonate at 14.074 Mhz.

Re: Considering a club project kit
I put it on standoffs for now until I find a suitable case. One slightly annoying and inexplicable (so far) feature is that when switched to dummy load, the circuit still includes the antenna in

Re: QDX: Sometimes only getting RX after PTT
Thank you Ryan for the response.? Based on that information, the command to drop the PTT line is being missed by the QDX.? This could be a software issue on the QDX side that it cannot decode the
