I have a bucket load of clamp on ferrites from work, and have them all over all
the cables on the flex and the computer.
The computer seems to be doing fine, but no matter what I do I can not get more
then 1/2 power out of the 3000.
I had forgotten to ground the computer, but put one on after the glitch.
I reset the database, and changed the option to show the flex icon in the
system tray, and that pops up when the radio is turned on.
Into a dummy load, on ssb, am, fm, max power out is 50 watts.
Current draw is 10 amps max, so it looks like I lost one of the output
transistors.
This is the same amp I drove with the flex 5000, the icom 756 pro3, etc.
At first I thought the computer reset because the power kind of sags when the
amp kicks on, but I am not sure.
Everything still works (even into the amp) but the 3000 output is half what it
should be.
It looks like I will be contacting flex to send the 3000 back.
I so wanted this to work, as I love the flex receivers, and now I may be stuck
with something yucky like a pro3
(for the band scope).
Or, I could order output transistors and fix it, but it might just happen again.
The amp only takes about 8 watts to drive it, and if the devices blow out at
that power, its too fragile to use...
What I do not know is exactly what happened, did the computer have issues that
did something to the output devices, did the brown out cause it, rf?, or what...

If the OS is Win7, make sure you are using the legacy 1394 driver instead of
the TI one.
If you are reliably seeing 50% utilization, you are really on the edge of
"too little processing power". Make sure you are not running anything else when
you are playing radio!

Well, I got my new 3000 today.
Installation took about 10 minutes, another 1/2 hour to experiment and set
up all the settings to where I liked.
Then it was hooking up the microphone and setting the EQ and levels up.
I tested the atu, and the power output, and everything was fine.
Cpu is running around 50%, dpc was 250 us.
Then, in the process of transmitting into an amplifier, the computer did a
temporary hiccup, but sort of restarted psdr.
After that happened, my maximum power output dropped to 50 watts.
In AM, setting the drive control to about 10 gives 40 watts out, modulation
makes the power go down, and the alc is sitting at 0 all the time, with no
audio.
Shutting everything off and restarting it makes no difference.
How do I do a database reset?
That was what they always said to do, no?
The radio was working well up to when it was not, some delay through it as
the computer is on the slow side.
Another thing I noticed is the computer did not see the radio when I
powered it up a few times after I had turned everything off.
The speaker icon in the system tray would do something when the radio was
powered up, then I went into device manager and checked the fire wire card, and
its there and ok, then the computer sees the radio when its powered on.
The card is a Roswell with the TI chipset.
Crazy stuff...
