I use a XV-222 also and will confirm the faults Duffey listed. I tried
running 20w on FM and blew out the final stage amplifier module. If you
look hard enough, you can find a warning/limitation about high duty
cycle usage in the manual.
Yes, it drifts from cold start. As James says, likely not a problem for
a fixed station. Another, minor problem, it doesn't have a way to make
a small freq adjustment to the crystal. My unit is about 2khz high,
once it settles down.
