Congrats, and welcome! > I did my voltage measurements with my own (cheap) DMM, not the > internal voltmeter. Maybe a silly question, but is the DMM's batteries fresh? If it has the half-dead cheap old batteries that it came with, the reading may be off a bit too much. A sanity check of comparing the measurement to ones done using the internal voltmeter could help detect if that is the problem if you don't have a fresh battery on hand. > I measured the voltage on the LM29307-8, and it has 12.23V at the > input, but only 7.53V at the output.

I would expect closer to 8V out of the LM2930T-8 but it is with spec (7.5-8.5V from the LM2930 datasheet), and the input voltage is fine (should only need 8.6 or 9V input to work correctly. -Michael, VE3TIX _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
