IC-91AD, TH-28A, TH-F6a

[NN5I]

I received today (from the wife of a good friend, N5SEW, who passed away about a year ago) a box containing five handhelds:

2 Icom IC-91AD with batteries, no charger

1 Kenwood TH-F6a with batteries, one wall-wart charger (which also works with IC-91AD)

1 Kenwood TH-28A with four batteries and no charger, but I already had a Kenwood BC-15A charger that works with these batteries.

These likely are all in working condition.

No instruction manual with any of these, but I've downloaded PDFs from the Internet.

Either these are darned complicated radios, or I'm even more senile than I knew. Probably both.

Any general advice from folks who know and use these? Trying to decide which to tackle first (after I get some batteries charged, good grief, they're all totally dead).

Interested in all comments about features, ease of use, etc.
