RE: Found the FILTER MAN



Doug,
I don't have the full picture..
You have a dish with a helix feed on S band into a UEK-3000, out at 2m into
your rig. I would assume you copy AO-40 MB ok.
Now, here is where I get foggy... What are you using as an uplink?

Rig: ?
Band: 70cm or L Band ?
Antenna: ?

My assumption is that you presently do not have any uplink. If that is the
case, the simplest way to up-link is an M2 70cm crossed yagi driven with the
rig at 70cm.
If you wish to up-link on L Band, you need a 1.2Ghz TX and either a dual
band Patch or Dual Helix on your dish, or a yagi or loop antenna on L Band.
Dual Helix or dual patch is much easier. If you use a common dish you will
likely need a 1.2Ghz filter on the front end of the UEK-3000 to not desense
the UEK.

Give me more details on what you have and what you wish to do.

Gunther,
Ok, let me see if we can make some sense of this,  I also have a uek-3000 at
145mhz for down link. the dish is a n3iyr with helix feed.  What do I have
to do to get the 435 out of the rx so I can hear myself?
