I purchased a Yaesu FTDX-400 from an online auction. I have not

a circuit breaker in a power board popped out. I reset the CB
and there was a loud bang and a puff of smoke from the area
of the power supply. A quick look under the chassis did not show
anything obvious.

Well, get out the meter and start looking. Apt to be a bad capacitor
or a bad diode (or something else failed due to a shorted capacitor).
The meter will tell you for sure.

Your main worry is collateral damage from bad caps.

He has a lot more problems than that. It was the CME last month that
caused his problems.

He got that radio right after he finished converting a rig from 1 meter
to 2 meters :)

The next thing he'll ask is how to get the rig working on 11 meters.

The FTDX-400 will remain with one meter although meters have been
replaced by LCDs.

The next thing he'll ask is how to get the rig working on 11 meters.

Its certainly possible given it has the ability to add three 500Khz
bands.

Biologists agree that descent with modification is one of the most reliably
established facts in science. Discoveries in evolutionary biology have made
a significant impact not just within the traditional branches of biology,
but also in other academic disciplines (e.g., anthropology and psychology)
and on society at large.
