Icom R71: How well does it stack up today?

On a different note, how common is the key bounce? Do most units end
up suffering in the long term?

You may want to ask that on the R5000 Yahoo group. IMHO far more worrisome
is the dreaded dots......

This is where the display only shows a row of dots due to the main PLL
(phased locked loop) becoming unlocked (going off frequency) because it
was potted in a rubber compound, which over the years absorbed moisture
from the air.

The repair entails unsoldering all of the parts in the PLL circuit,
removing the remains of the compound from them and putting them back. In
many cases, some of them have been corroded beyond use and must be
replaced.
