The P* dish is a Channelmaster 75E or 84E.. which, the 75E is the same as the *C 75E dish.. (just a different brand on it) The 60E dish, which the OP has is smaller, but works fine for the purpose. However, the LNB will not work, to get both sats.. fine for one, but not both.
Then again, if you pick up an old 75E P* dish for basically nothing, then you just need the *C 75E LNB, which would be much cheaper than the entire dish.
However, the OP did mention that the 60E was the largest he could realisticly fit on his balcony, so he should be all set. besides, the signals he is getting is more than sufficient.
Ice: My current setup has an odd delta on EBNO readings.. they are as follows: (3 digit numbers are the channels)
326: 8.5 361: 9.3 465: 8.6 534: 6.8 542: 8.1 544: 6.3
Now, I know the 8s are good, but the only explination I have for the 6s is that perhaps my skew is off by a degree or two? Are those channels on the other bird? Or are they slightly lower powered, and I shouldnt worry?
