The VU is designed for weak signal work (high sensitivity), so there is
more of an opportunity to overload down link. Try using a narrow
bandpass filter on the down link to reduce the IMD mixing.

I have one of those and I've used it numerous times, including several
times at Field Day, with my FT-847. The first time I used it in fixed
elevation with the "15*" bracket it comes with, and I was very
disappointed. I then mounted it with my G-5400 Az-El rotor, and it made
a tremendous improv
Alan, thanks for this tip. I wasn't the original writer of this issue but will
try it. When I do reduce power it gets rid of birdies and intermodal on the
downlink but makes it very marginal to make contacts near the horizon. This
should help.
As a chance question, would simply hooking up th
Paul,
I use separate antennas, but have found that setting the AGC-T properly is
essential. If set too high, it will amplify the noise, and it wipes out the
downlink. By backing off, per the instructions in the manual, RX works very
well.
If I found the correct antenna on the Gulf Alpha site,
I use an Arrow Antenna for 144/433 work and it plays very well with TS-790A.
At max 144 power (35 watts) it generates a few birdies on 432 downlink but I
reduce power to about 15 watts and they are gone.
The antenna is up about 15' with 25' runs of RG-213 to the rig. Bon, NZ5A

Is anyone using a 5000/VU5K with a dualband yagi for satellite work with any
positive results?
I recently put up a Gulf Alpha EZ Sat Dualband Satellite Yagi and it the
performance has been very disappointing. The Flex RX downlink is completely
'overwhelmed' during TX on the uplink. The RX panadap
