I bet it has a self destruction device....
Sounds like a job for our newly created Space Force to have fun with a goal of bringing it down safely? over US territory and give it a good examination.

If you can¡¯t enjoy the absurdity of it all, please just mute this topic..... these interruptions to windings and blown components are relaxing. ?And to boot many folks here actually fly balloons and it is interesting if not hilarious, hey, some want to send an F-22 after a balloon.... that¡¯s not a fair fight !

Re: QDX not receiving after replacing blown transistors
These DC-DC converters look interesting - is there any rule for figuring out which ones are going to generate RFI and which ones would be clean? Or is it just a case of pot luck then cover the wires with ferrite chokes?

RESOLVED: Turns out IC4, the FST3253, was the culprit.
Thanks to everyone how responded and helped out.
Its a testament to how awesome this group is.

Nothing new. When Sputnik 1 was laughed [ LAUNCHED - thank you dictation software], the Daily Express asked why the RAF didn¡¯t go up to shoot it down.

There is an outcry to shoot it down, I hope they capture it.? Maybe a nano-sized hole made by a laser would do it.? In all honesty, it's not any worse than an orbiting?spy satellite.

Re: Corrosion on IC pins (QCX+ build)
Thanks, Cliff, for the heads up! This is the plus version but I¡¯ll try to be conservative with the voltage.?
I tweaked the BPF a bit more: took a winding off from both L3 and L2 and this gave me more range for adjustment. Now I get about 4.5 W @ 12 V and closer to 6 W @ 13.8 V. These readings are not from a calibrated meter so take them with a grain of salt.
Ted, I¡¯m also planning to use the radio with a 4S LiPo battery back and a buck converter. About 12v should be enough for a signal in QRP range. Lower voltage also gives the buck converter something to work with.?

Maybe after the combined armed forces is able to create a leak in the balloon envelope .... they can tow the descending balloon to Roswell NM which could use a boost after Covid.

As soon as I bring up the card on WSJTX 2.6.0 LED2 is OFF?
John

I received a new 20-80 Rev 4 QDX some weeks ago and now have time to place it in a case.
It is a built and tested unit direct from QRP-labs. It is a 12v unit that I am running at 9V. Power on -- I see .13 A.
LED1 fast blinks while loading code then constant LED1 and LED2. I am guessing I should not have an LED2.
I am able to use PUTTY to access the settings options.
What should I lookfor before I slide this card into the case?
