In practical terms, today, there are some significant differences.
R-71 is still relatively well supported by ICOM. R-5000...not so much.
Displays are no longer avaiable for R-5000. And both require attention
at this age. R-71 will need ......


Two points missed:

1. The R-71 has it's microprocessor's programing on a battery backed up
RAM chip. When the battery fails, the radio is dead until it is
reprogramed. Someone sold an update kit, I have no idea if they
are still available.

The other question is how much longer will ICOM be able to reprogram
the current chips? One would hope they keep that equipment around
but old computers fail, programs no longer run after operating
system updates etc.

2. The R-5000's had a problem with the rubber potting compound on the PLL
board. A nasty job, the easy way is to unsolder ALL of the components,
scrape out the left over compound and install new components.

As the components become hard to replace, a repair will be to use a
tweezer and dental pick to remove all the compound by hand, hoping that
you do not damage anything and nothing was corroded to the point of
being unuseable.

I did it that way, and if it was not for the fact that the cost of
shipping each way to a competent repair person was more than the
cost of them repairing it, I would not have.
