I am trying to drive an amp with 20 watts with my VU5K. I can not get a
steady ouput from it. It will start out at 20 watts for a few seconds and
then it will slowly drop to 14-15 watts after 30 seconds. At full output I
am getting 52 watts and it will remain steady within 2 watts. But at the
lower wattages it will not.
The case gets very hot also after about 10 minutes of running. If I run a
fan on the Flex 5K case, that l helps the output drifting. I took the bottom
cover off and the fan is working. It doesn't seem like it does much.
I sure would like a solution to this problem

I have the same problem. As I understand the low RF power output of the Flex
5000A VU module is a known defect associated with trouble ticket DE725 / SW
Defect #703.

I just purchased a 5000a with VU module, on 144 mhz FM output is 42watts
this
is into a dummy load with Bird Meter, on SSB output only 15-20 watts. Anyone
else had this problem? Thanks Todd

Given the power output of the Flex 5000A with the VU5K option the only thing
it is capable of doing is driving a linear amp. Even at that, it is not all
that stable at very low power output levels, so be careful just what kind of
linear you might choose to drive with the Flex.
Don't make the mistake that I did and try to operate the Flex 5000A with
VU5K installed to drive a 2m or a 70cm transverter. Having been quite
unhappy with the 2m performance of my Flex with the VU5K installed, I
purchased a German Kuhne 2m transverter to connect to my Flex 5000.
With the way the VU5K is configured into the Flex 5000, it cannot be done,
as the VU5K implementation does not allow either an additional 2m or 70cm
transverter to be operational with the Flex. If you do not have the VU5K
option then you could use the Flex with any number of 2m or 70cm
transverters. This to me is a very serious design flaw and along with the
low power output and noisy fan are some of the many reasons they are no
longer offering the VU5K option.

Todd, Assuming you have the bird connected via a good short cable close to
the back of the Flex, 42w is a bit low on 2m. Flex rates the output at 60w
but admits few make that power. Apparently the power modules on both v/u
bands are consistently low with output power. I get a little over 50w out on
2m and around 45w on 70cm also into a bird wattmeter. As far a your SSB
reading goes, you should be using a peak reading meter which bird has an
add-on board for the model 43 you can purchase to read peak power. If you
are using that, then I suspect your audio levels are not setup up correctly.
Another test you can perform should you have the equipment to do so is to go
into the "transverter" menu and check the box to disable the amp on 2m. At
the 2m antenna port you will now read the "drive power" that is used to
drive the internal amplifier. Using an HP435 power meter I am getting 96mw
of drive power. If you noticed that the drive slider on PwrSdr menu reads
0-100 (watts) which is accurate on HF but on v/u is only relative power out.
I discovered on v/u the 0-100 accurately reads in millwatts which I believe
is the drive power to the internal amplifier modules. This low level can but
used to drive transverters that require 2m as an IF. Unfortunately, you have
to go in and out of the transverter to enable the amplifier check box to go
back to high power on 2m but first switch out the transverter. I have
requested Flex to rewrite the code to allow users to access that via a UCB
function. I do not expect this will happen with the 5000 now discontinued
along with the v/u add on.

I got the following from ?tekboy? at DEMI.
?No problem with the transverter operating in the satellite range. You just
need to decide how you want to do it. The RF range of the transverter is
about 430-440 MHz. The problem, since it is a converter, is the IF frequency
range. So simply, if you have a transceiver or receiver that will operate
above 30 MHz, just dial it up! Many are doing this with the Flex Radios. 436
Mhz would equal 32 Mhz in the IF range.?
Can the FLEX-3000/PSDR be ?adjusted? to function as a transceiver (receive
and transmit) in the 28-38 MHz range to drive a transverter in the 430-440
MHz range with the IF in the 28-38 MHz range?

The 5000a is not discontinued. If you aren't sure, go to the Flex website
store and you will see that you can still buy a Flex 5000a. It is right
there on the front of the web site with a "Buy Now" button still prominently
displayed.

HI BOB,
I assumed the v/u was discontinued because they told us they were having
problems getting filters and maybe other parts. I should have been more

I actually asked the question and was clearly told that they are no
immediate plans to discontinue the 5000a.
But think about it, why should they? They have no product to replace the
5000a.
