Yeah, but that was a Japanese radio that had been
booby-trapped to get us Americans back for "the big
one" in 1945 !
If you get 105C rated tantalums they shouldn't get

co-incidence.
Go to the Motorola section, then the Spectra Mobile
area. Check out all the nifty articles near the
bottom. One of them addresses the capacitors issue.

I noticed the same thing in a Spectra I purchased used late last year. This

At work, we have a fleet with several hundred 800 MHz Spectra C5 and
