Hi Fred Of course you are right on all... but seriously, if you think that's bad, you should hear what I have to say about the physicists! In my internal ranking system they are ordered in decreasing

Yes, I can hear signals out of earphones with antenna. With dummy load, I can hear the loud tone with BPF peak setting, but trimmer capacitor has no influence on amplitude. With the other

Just so you know, Hans, ....I resisted sending one of those emails when I decided not to build my QCX-mini for 160m as I had initially planned and asked you to swap the filter parts in the order. I

Roelof, thank you. I've just tried that and it gives a much better result. Pin 11 with a straight key/constant send was 4.98V and the voltage at the dummy load was a constant 13.8V. I've also

Hi Hans and fellow QCX-ERS, My post wasn't intended as a question! or a moan, but merely a statement of where my tracking was at that moment in time.in keeping with the topic. Having read

Well you certainly tested your fix thoroughly Hans. Perhaps both the input and output caps should be low ESR for additional risk reduction? The App note 88 from Linear Technology that Simon VK3ELH

Hi Tim Thanks for the suggestions which are all very good... No no nothing is in jeopardy. The youngest lab tech here is 5.5 months. That means another 17.5-something years of mouths to feed. I

I would check the RX/TX mute switch, Q5 and C33 as that is how the receive signal gets to the receiver from the low pass filter. And although you say T1 is 100%, I wonder what would be the result
