Its still not doing anything. Its making a good conversion piece as a door stop.

General Radio Discussion / HF Global Weekend in October?
« on: October 18, 2019, 1550 UTC »
Hello, can anybody verify when the Global HF Weekend is going to be?
When the weekend goes on, what are some good places to listen?

I have a cheap-o PS I got from amazon. Its really stable and has its own variable fan. Says it can do up to 15A.

I've got an inverted L that is about a 1/4 wave on upper 80m where the AM guys are. There's a ground rod at the feedpoint and thats where I put the tuner.

Its not over 'cause the OP's in da house, woot woot!
To prevent AC with my 24V AC to DC power supply, if I were to have a second go at it, I would wire in 2 x 12v lightbulbs so they make a 24v load to the power supply.
So my sequence would go like this:
Turn on PS and make sure my 24 volts worth of lights are powered on
Make sure xmtr is off
Then plug PS into transmitter
Then turn on xmtr and start calling CQ
That way I figure the PS would be producing DC before it goes into the transmitter.

Well, for posterity's sake, my old one didn't pass the test and my new replacement did pass the test. And you mentioned there are 2 devices in the FET, that would make sense because I heard multiple pops...before it stopped. R.I.P.

Dude, I ain't lyin' or tryin' to slander you, Stretchypants. 
I'm a member of a shortwave pirate forum and I've got my own conspiracy theories about you and your extraordinary repair policy, so there.
Here's a nice video of the method I used to test the mosfet with my multimeter:

I see. Thats why Stretchy had me check it with an oscilloscope. It has a sinusoidal wave where there should be a square wave.
Thanks for your input, I'm done with it for now. I'll use it as a decoration, kind of like a star wars model with battle damage.

Its not all "unicorns and fairy-free," it costs money to ship it there and time/work to pack it up to send it on an international journey as well as the time without a transmitter.
Messing about was fun.
I think one of the integrated circuits broke and that blew out my transistor.
Does anybody else have problems with their stretchyman transmitters?

FWIW, I removed the old MOSFET and it failed the test with a multimeter. So I ordered a new one and installed that today. It worked but it made a big pop noise. I turned it on and off and it stopped working again after the 3rd time.

I've got a venerable Stretchyman 40w GaN transmitter for sale. It worked great on the upper 80m ham band to make contacts where I never used it for pirate purposes.
Its broken, it doesn't transmit. It made popping noises when I plugged in my AC to DC 24v power supply while the unit was on. I should have plugged it in with the the power supply and the transmitter off,
then turned on the power supply,
and then turned on the transmitter.
Stretchy offered for me to send it back for repairs but if somebody will buy it as is, its more convenient for me.
Comes with the frequency programmer and some files for a few frequencies.
PM me if you want to do paypal. Cost around $300 new.
Sell for $75 with shipping in the continental US.

Hey Pigparts, they both kind of smell electronicsy. The supply as a problem is a good point. But I tested with a battery and still no avail.
