Contact QRP labs. Not an issue for this forum.

My money says it shows up in a day or two. I’ve seen that trick too often to be fooled. Aside from that, email Hans directly. Mike WM4B

Sorry, I finally looked at the schematic a bit closer .... 5 volts is coming from pin 8 of IC3. This is a NAND gate so it is high unless both inputs are high. It will have 5 volts DC on it except when

Vance, you are correct, the BPF adjustment is independent of the volume control setting. The IQ Bal and Hi and Lo Phase null adjustments are the ones that are dependent on the setting of the volume

Sounds to me like you did a great job. 20 has been dead lately. Try late afternoon and early evening. GL, Gary W0CKI

Curt and Vance Re. +5VDC on the coax connector, If your DVM has fairly wide bandwidth it is possible that it is reading the average of the RF above ground. This happens when the RF is floating

Curtis: I was under the impression that the peak level on the bpf isn't affected by the volume. I guess I could check it again and make sure. I was able to get a peak that is between fully open and

I assumed he meant the spoon you use for spoon feeding all those who keep pestering about the QSX. ;)

Gents, Don’t worry about the 5V on the coax centre pin. It comes from the output of IC3C (pin 8) - at least on the QCX+. It’s possible that Hans has used different pins on the mini, I haven’t

Vance nice work, just built a 20m mini here. the 7 level on BPF peaking means little - it changes as you adjust volume control. as long as you get a pronounced peak, all is well. the other

Vance, that high 7 range reading is probably fine, as long as you are not at fully open or full meshed on the C1 trimmer. I checked my QCX just now with DC reading DVM on the BNC connector and find 5

Hi everyone, I finished up my QCX Mini (what a fantastic kit!) and noticed a few things while doing the alignment. Firstly, I was only able to set the BPF Peak to high 7, almost 8. Is this too low? Is

Ikea recently had a clearance on their AA 2450 mAh NIMH batteries in W & VE. Made in the Panasonic factory in Japan, AFAIK. A great choice for all the reasons Richard outlined... If I were a SOTA

These days it seems everybody wants the convenience of a tuner built into the radio but I would rather the tuner is at the far end of the line. That approach has some great advantages. In the picture

NiMH AA cells. Widely available, cheap, safe, you probably have some already, interchangeable with other devices etc. For QRP they are perfect. -- 73 Richard G4TGJ

OK , here is wet afternoon with Hans LEFT THE BUILDING (as per Elvis ) idea Nbr one. basically all analogue transmitter design - AM. It is a 6W PEP AM transmitter design for forty but can

I did something similar like VE3VXO for a simple antenna / tuner a while ago. Mine is a bit more bulky and made from some plastic plumbing supplies. It contains - A simple L match. An LED indicator to
