diagnostic guide for uBitx v5? #ubitx #ubitx-help


 

I found the following diagnostic guide for the uBitx V3:

/g/GCBG/attachment/105/0/uBitxTroubleshooting%20manuala.pdf

Unfortunately I have not been able to find such a document for the uBitx V5.

If such a document does not yet exist - it would be great if somebody with a
working uBitx V5 could take the measurements and update the uBitx V3
document.

Thank you,

-jens

PS: My uBitx V5 is correctly broken (both for RX and TX) due to overheating and
I need to know the expected voltage levels for the uBitx V5 'measure points'
in order to isolate the problem. More on this investigation can be found in the
following thread:

sorry about your malady.? since there are only a few changes from v3 to v4 to v5, I would start with that data.? the largest change in biased parts between them is the audio amplifier.? all the other major parts - PA, driver, bidirectional amplifiers are the same or very similar.? as you find anything suspicious in your measurements, list members can help if you post the data to your other thread.?

overheating - do check the regulators first to see what they are doing.? I will go check out that thread.?
