Re: Bayou Jumper troubleshooting audio chip

Jim, N5IB

Get in touch with Steve the Kitter ... his email contact info is at the bottom of the kit web page.
He'll be able to set you up with a replacement chip.

In the meantime, do you have a way to measure the supply current being drawn by the radio?

If so, unplug your earbuds, turn the radio to receive mode and look at the supply current . It should show a brief high current spike for a second or two as capacitors are charging up, then drop back to a steady 25 mA or so.
If it stays above say, 30 mA after 3 or 4 seconds, then turn the radio off. Pop U1 out of its socket and repeat the current test.

Report back what you discover.
