hi guys,

I've got a bunch of Icom IC-F4s radios here, two of them, the channel display
flashes constantly, and it doesn't seem to transmit or receive.

Another one, when i key up, the red light comes on for a brief second and
goes off, and the display starts flashing. When I release tx, it stops
flashing.

Are the radios simply locked out, or are they faulty?

When the display flashes, only the name flashes. Any indicators like "LOW"
do not flash.


thanks!
