The space between the small transistor Q104 and the larger Q103 does not allow for a form-fit wire of almost any reasonable gauge to fit between the two—much less moving a sharp-tipped iron into

This is very similar to my release of smoke : Please refer to /g/QRPLabs/message/108631 This looks like a?systematic problem!

Hello Daimon Yes, I confirm - I have heard of this issue and I will investigate it further as soon as I have a chance; I have it on my list. 73 Hans

Practice (on other disposable boards) makes perfect

I agree on cutting back the leads where possible (also re solderable after testing) but the ChipQuik for Hi Reliability systems is surprising as their low temperature solder alloy is not fully

Here we found it easier to achieve precise alignment of the SMPS boards if the spacer nuts are NOT drilled out. The reason is that drilling them out, or shoving a soldering iron through them, either

Hans, Just completed my order for 1 QMX Kit + enclosure and received confirmation. Thanks for your help and honesty helping me make my decision. Glad to be aboard,

Hans, in my mind your a great engineer. Scientists (physicists) determine how and why, engineers use that knowledge to create. Member of the Hans Fan Club!

1V/division on the vertical scale, with a -3V offset 50ms/division on the horizontal scale Not quite the full second you requested but there didn't seem to be anything going on further

What are the horizontal and vertical scales ? 73 Kees K5BCQ

Hello Rod I don't know what revision of the firmware you have. It's worth upgrading it to the latest, which has a band configuration screen for specifying the band limits (frequency limits) and which

Hello Billy My apologies, I think I was trying to be clever responding to several people in the topic in one post, but I confused you with the second poster who really was (is) Willie N1JBJ Great

Jonathan, Thank you very much, let me look at it. 73 Kees K5BCQ

Hi Ted. I am not nearby, but will replace it for you if you can send it to me. I have build many many radios, even the QMX that is complete and working. I love smd and associated things like this
