Stretchyman 40 W TX Reliability Modifications
« on: September 10, 2020, 0634 UTC »
It's been a few months since I visited this forum or posted here. I've had other things going on (e.g., keeping my employment). You might remember I wrote up the issues on Stretchy's 40 Watt TX here:https://www.hfunderground.com/board/index.php/topic,67747.msg230885.html#msg230885

Some of you wrote me to tell me that you had exactly same problem. Some of you asked for more detail. I finally got back to looking at what needed to be done to modify for reliability in August and this is the result. For the two of you that wanted to see this, here it is.  :D

EDIT: Fixed the title. It will be great once I learn to spell correctly.

Thanks for sharing. As an engineer I find design reviews/improvements very interesting to read. You often learn something you can later use yourself.

I have developed a drop in PCB and most have already received one, for any that haven't please PM me.

It delays the 24V until the 12V and oscillator is fully up.

Str.
'It's better to give than receive' so why RX when you can TX!

                            Buy one from me, NOW!

Great discounts on ALL my transmitters if purchased via HFUnderground
