"I will not work on that dish!"

[RT-Cat]

This is the most unheard of thing I have ever heard of. You need to read carefully.
You have three receivers: A, B, and C. You have two C-Band dishes: 1 and 2. Both have the same LNB on them. Both dishes are set to 103.
Hook up receiver A on dish 2, works great. Remove it and hook up receiver B on dish 2, works great. Remove it and hook up receiver C on dish 2, will not show more than 15 for signal. But move it over to dish 1 and it works great! How can a receiver decide it will not work on a dish but it will work on a different one. Again, same LNB. This just does not add up.
Yes, the setting have been triple checked.

Could that receiver be sensitive to the length of the center conductor on your F connector? Just a quick thought I had, probably not worth much.

Good thought bpalong, but I think I have the answer. The unit worked on the other dish a second time and then it stopped. Now it will not work anywhere. Bad unit, dead. Needs to go back to Amazon.

Do you get the same result on all transponders on 103?

Sounds like a defective tuner

All transponders and all satellites. Signal bounces from 5 to about 30. Quality never shows. It must be very sick, ill, dead.
