GM328 Put into case and initial tests

Posted: 09 Jan 2021 09:02 AM PST http://m1kta-qrp.blogspot.com/2021/01/gm328-put-into-case-and-initial-tests.html


Ran it off a desktop power supply measured at 9.1V DC.



Screen reports 9.1V DC.
Ran through the self test using 100nF capacitor and a set of joined wires
to short probes 1-2-3
A 33nf capacitor with this reported as 33.29nF which tallied with another tester.
Bit cold in workshop right now so will post a few more images of random
junk box/salvaged components then pick this up another day but on face of
it seems to be working fine.

GM328 Build board stuffing.

Just followed the silkscreen placing components.


















Not terribly difficult. The Pins on the uPC were a bit bent but
straightened fine.
Noticed a few things missing.
One 27K resistor and couple terminal blocks.
