so my FT-2900 started to not here things very well, and did it at about the 8 month old mark,
it finally got the the point where it could not here strong repeaters,
and I have been working to solve the issue for years now,
turns out a ceramic filter died,
it is a LTM450FW
looking on the web, quite a few people have had this issue with this ceramic filter.
they are pretty cheep to get a new filter, and possible to change
having just figured this out, I still have yet to order one, but will soon,
the easy way to tell what is going on is to turn the radio to narrow band,
it works just fine on narrow band.
so the real reason I post this is because if you have a radio start to die on receive from filters going bad,
and you really can't get new filters,
try narrow band,
you might just be able to still use your radio,
and others can here you with lower audio if they are still set to wideband (like a repeater)
