Hi!
I have a FT990 that is refusing to communicate to my PC. I tried two PC, =
two logging programs that use to work, replaced cables, etc, without =
luck.
The problem began to show up slowly but now it is steady.
I have checked the sig with my Tek scope and this is what I have seen:
When an update command is sent to the radio, the CAT indicator comes on =
and there is a signal coming out on SO. Traced the sig all the way to =
the comm. port of my PC and the sig is there with the correct levels but =
nothing happens.
If I do a Set OP Freq command, the radio will respond to it without any =
problem.
I did a update command asking for 1508 bytes (U=3D0) to have time to =
sync on something. The only thing I think is kind of strange is that the =
shortest info element is less that 2.2ms which is the shortest time for =
a baud of 4800.
Ran out of bullets...
Could it be a problem with Q5004 MCU oscillator?
