I did see the power and that is a good point, However the power consumed by the Primestar LNBFs can far exceed those and are not at all consistant. I have weeded out 2 that were 800 ma or more. So, 160 ma did not bother me. Actually, I notice a difference in frequency deviation, but no units, and that was the question I started the reply to ask. In my ham VFOs 2 Hz would not be a problem. 2 Kz would be a minor problem but 2 Mhz would be a serious problem... And 1% -- you had better know about it.
