RV Setup using d12 500 and older 18 inch round dish and lnb

azmith at 230, elevation 37  all connections are tight. used compas for azmith, used handheld signal meter and signal meter on screen getting all zeros to all transponders tried with a line amplifier and without. not getting a cabling error onscreen.

azmith at 230 elevation at 37 good line of sight, all connectors are tight, installed line amp, used compas and handheld signal meter and onscreen signal meter. getting all 0 to transponders

As peds says, the azimuth number is just a starting point, you can't expect to be exactly on the satellite just by setting the dish to what you think is the correct azimuth.  Move the dish gently to the left of the azimuth and then if you don't find the satellite move it back to the right.  You should pick up the 101 satellite if you have the elevation set correctly. Note also if it's a simple hand held signal meter it won't tell you which satellite you are receiving, so even if you see signals it might be the wrong satellite.

ok found signal, now have installation status error red x in box for odd 13volt at 101degree

that means that your signals are below the DTV standards.  your signals should be 90 or above on the 101 with some being low or zero.  but for a temp set up, low signals might be ok.  if you want to improve those signals you might have to adjust the elevation 

Thank you all for the help, its up and running. Touchy SOB. Young Skywalker has much to learn.

yes, indeed.

Remove the line amp. You only need to run the cable between the dish and the reciever.  This could be part of your problem.  Use the recievers built in meter to read your signal levels.  18" round setup should take you less then 10 minutes.

All new endeavors (including aligning a dish) have a learning curve.  The size and shape of the curve can vary considerably.
