Re: V4 TX problems and new finals #ubitx-help


 

Evan, Mark, Raj, Anthony, & Co.

What is marveling about this lovely radio is its resilienance to stupidity.

What is marveling about this community is how unbelievably kind, helpful, generous and talented you people are.

How many times did I turn the bias pots the wrong way? Counter what? And the driver adjustment does what which way?? Why does the uBITX go dark and reset when my DVM probe slips and shorts the? IRF510 pins?? Which pin is the gate (again?)?? Why does my uBITX go all Chernobyl when I put 2Ov on the PA brown wire and fail to notice that I'm stuck in TX? WSPR digital mode 100% duty cycle for 10 minutes with way too much drive?

Why didn't I study electronics in school? Okay there were way more girls in English class, but still...it would be sort of useful around now...

I have to draw little cute diagrams of transistors and label them because I can never remember what lead is what. I feel like a first grader learning how to tie their shoes.?

If I set the bias current drain, then the voltage on the gate can't be zero.? Ah....so there is an error here...wait...is this that well meaning dope Don?? Good grief, he? can't get him out the door if you pushed him -- electrically. Hahah.

And I always feared that my problem (s?) are due to "operator error". I seem to have lots of that. Hahaha.?
?
uBITX? is just humility spelled backwards.? It is sooooo much better and smarter than I am.? But, that makes it really fruitful to study and poke and add to.?

I'll get back to Lab Class and report out on the "Rs" and the "TPs" and the counter clock wise what? Hahah.

Thanks a hundred million.

Don
